The South Node is one of the two lunar nodes in astrology, marking the point where the Moon's path crosses the ecliptic. While the North Node points toward growth and direction, the South Node describes what you already carry: familiar instincts, ingrained habits and comfort zones that feel deeply known. It is often read as the karmic residue of past patterns, the skills you arrive with and the tendencies you may need to loosen rather than reinforce. The Free South Node Calculator from YesAstrology works out your South Node placement from your birth date, time and place. Enter your details and you will see the exact zodiac sign and house your South Node occupies, along with the North Node opposite it. The result is free, instant and ready to use alongside your full birth chart. Your interpretation follows a clear framework. The South Node sign shows the qualities and survival strategies you lean on by default, while the South Node house reveals the life area where those patterns play out most strongly. Read together with the North Node, the pair maps what you are moving away from and what you are being asked to develop next, giving you practical guidance for relationships, career and inner life. ## What Is the South Node? The South Node (also called the Descending Node or Ketu) is the point on the Moon's orbit where it crosses the ecliptic moving southward, always positioned exactly 180° opposite the North Node. It marks the zodiac sign and house of patterns, talents and comfort zones carried over from prior experience — the familiar territory you default to under pressure. Because the two nodes are always in opposition, the South Node's sign is the exact opposite of the North Node's sign: a South Node in Capricorn places the North Node in Cancer, and a South Node in the 10th house of career and public standing pairs with a North Node in the 4th house of home and roots. Whichever sign holds your South Node describes abilities you can draw on instinctively, but also the habits that keep you looping — for example, a South Node in Virgo may over-analyze details in the 6th house of daily work while neglecting the Piscean 12th house need for rest and surrender. Unlike the Sun, Moon or Mercury, the nodes do not rule a sign or hold a house cusp on their own; they are sensitive points whose meaning is read through the sign they occupy, the house they fall in, and any conjunction or square aspect they form with planets such as Saturn, Venus or Chiron. A South Node conjunct natal Pluto, for instance, intensifies the pull toward control patterns, while a South Node square Mars can manifest as reflexive conflict habits. ## How Does a South Node Calculator Work? A South Node calculator computes the Moon's ascending and descending orbital intersection points for the exact date, time and place of birth, then reports the sign and house where the South Node falls. The node positions themselves are derived from astronomical lunar ephemeris data, so they remain accurate to a fraction of a degree even when the birth time is unknown — unlike the Ascendant or the Placidus house cusps, which shift roughly one degree every four minutes. Under the hood, the engine first converts your birth data to UTC, then solves for the Moon's ecliptic longitude at that moment and offsets 180° to isolate the South Node. House placement is then assigned using the selected house system — Placidus, Whole Sign or Equal House. With an exact birth time, the Ascendant degree fixes each cusp precisely, so a South Node at 3° Leo can be correctly placed in, say, the 9th house of higher learning rather than the 10th. If the birth time is missing, the calculator defaults to a solar-noon chart: planetary signs and the South Node sign stay accurate, but house cusps are treated as approximate and Whole Sign is often the safer reading. Once the natal position is fixed, timing layers can be applied: transiting planets crossing the South Node (a Saturn transit, for example, can trigger a two-year review of old commitments), solar arc directions, and secondary progressions that slowly advance the node by roughly 1.5° per 12 years of life. Comparing the result against the North Node axis and any conjunctions to natal planets shows which inherited patterns are being activated now — for example, a progressed Moon conjunct the South Node often coincides with a pull back toward familiar emotional habits.

Enter your data and the tool computes the mean node position, then reports both the sign (the archetypal pattern you default to) and the house (the life area where that pattern plays out most automatically). Under the hood, the engine uses the engine_key node-placement logic: it converts your birth time to UT, computes the ecliptic longitude of the mean lunar node, and then maps that degree onto your house cusps. House cusps are derived from your Ascendant using the Placidus system by default; Whole Sign and Equal House are available as alternatives when latitude makes Placidus unstable (above roughly 66° north or south). Because the South Node moves only about 1.5° per month, the sign is almost always correct even without a birth time — but the house placement depends on the Ascendant, which shifts roughly one degree every four minutes of birth time. If your exact birth time is unknown, the calculator defaults to a solar-noon chart for that date and location. This keeps planetary signs and aspects accurate (the Sun, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto and Chiron all hold their sign placements across a full day), while the house assignment for the South Node is flagged as approximate. Once you supply a birth time — from a birth certificate or family record — the Ascendant and therefore the house cusp degrees resolve exactly, and the South Node's house placement locks in. For example, a South Node at 14° Taurus in the 2nd house points to ingrained habits around possession, income, and self-worth, while the same 14° Taurus in the 8th house redirects those familiar patterns into shared resources, intimacy, and other people's values. The sign never changes for a given date; only the house shifts with birth time and location. ## How to Find and Interpret Your South Node Your South Node is found by locating the point exactly opposite the North Node on the ecliptic — 180° away in zodiacal longitude — so the two nodes always share an axis: Aries–Libra, Taurus–Scorpio, Gemini–Sagittarius, and so on. Interpretation begins with the South Node's sign, which describes the inherited skill set and comfort zone you already carry, and its house, which shows where that ease shows up without effort. The sign reveals the pattern; the house reveals the arena. A South Node in Capricorn in the 10th house reads as career authority and public competence already banked from prior effort, whereas Capricorn in the 4th house carries that same disciplined, self-reliant energy into family structures and private life. Read the axis against its North Node counterpart: the South Node in Scorpio (deep entanglement, control, crisis fluency) opposes a North Node in Taurus (steady value-building, simplicity, embodied calm) — the growth direction is literally the opposite sign on the same degree. Aspect dynamics sharpen the reading. A Saturn conjunction to the South Node tightens the grip of the old pattern through duty and fear; a trine from Jupiter makes the inherited talent flow easily but risks over-reliance on it; a square from Pluto marks the comfort zone as a site of compulsion that must be consciously released. Compare this with the 6th house of daily work versus the 10th house of vocation: a South Node in Virgo sitting in the 10th brings public reputation built on precision, while the same placement in the 6th keeps that precision confined to routine service. Timing is read through transits, solar arcs, and progressions. When transit Saturn or transit Chiron makes a conjunction or opposition to your natal South Node, the outdated pattern is pressured or wounded into release; a progressed North Node crossing a house cusp often coincides with a felt shift toward the unfamiliar growth edge. The South Node itself does not move much — it is the sky around it that activates the axis over time. ## What Does Your South Node Reveal? Your South Node reveals the zodiac sign and house where you carry deeply familiar, often unconscious patterns — the karmic comfort zone you default to under stress. Calculated as the point exactly opposite the North Node on the lunar axis, it shows what feels instinctively natural but may keep you repeating old lessons rather than growing into your North Node's direction. The Free South Node Calculator computes this placement from your birth date, time, and location. It uses standard lunar node ephemeris tables to determine the precise degree of the mean or true node, then maps that degree onto your chart's house cusps. If you provide an exact birth time, the tool applies Placidus house cusps by default to assign the correct house; Whole Sign and Equal House systems are also supported. Without an exact birth time, the calculator defaults to a solar-noon chart, which preserves sign accuracy and aspect relationships even when house placement becomes approximate. For example, a South Node in Capricorn in the 10th house points to ingrained habits around career status, public reputation, and control — patterns often built over many years. The opposite North Node falls in Cancer in the 4th house, indicating growth comes through emotional nourishment, home, and family. A South Node in Libra in the 7th house, by contrast, suggests over-reliance on partners and people-pleasing, with the Aries North Node in the 1st house calling for independent self-assertion. Timing activations are read through transits, solar arcs, and progressions. When Saturn or Pluto forms a conjunction or square to your South Node degree, those inherited patterns tend to surface for conscious review. Secondary progressions moving the Moon across the South Node often coincide with periods of releasing outdated obligations or inherited roles. ## South Node Meanings and Core Insights The South Node in each zodiac sign describes a specific set of inherited talents and repetitive habits you already know how to run on autopilot. Read together with its house placement, it shows where in life those patterns play out most strongly — and where the pull of the familiar is hardest to release. Each sign carries a distinct signature. South Node in Aries brings self-reliance and quick action but can default to impulsive conflict; South Node in Taurus offers steadiness and material skill yet clings to security; South Node in Gemini is verbally agile but scatters attention across too many threads. Water-sign South Nodes — Cancer, Scorpio, Pisces — carry emotional memory, protective instinct, or spiritual bypass tendencies respectively. Earth and air placements mirror this contrast: Virgo's analytical precision versus Pisces' surrender, Aquarius' detachment versus Leo's need for recognition. The house placement localizes the theme. A South Node in the 2nd house ties old patterns to income, possessions, and self-worth; the North Node in the 8th house then points toward shared resources and deeper exchange. A South Node in the 6th house shows habitual overwork in daily routines, with the 12th house North Node inviting rest and inner life. A South Node in the 9th house can indicate dogma or over-reliance on belief systems, while the 3th house North Node calls for direct, curious learning in the immediate environment. Aspects to the South Node sharpen the picture. A conjunction with Saturn adds duty and heaviness to the release work; a square from Pluto intensifies power struggles around letting go; a trine from Venus can make the old patterns feel pleasant and therefore harder to notice. The calculator reports these aspect relationships alongside the sign and house so you can read the full configuration at once. ## South Node and Love and Relationships The South Node in your natal chart shows the relationship habits you already know too well — the comfort-zone patterns you bring into love before you have consciously chosen them. Its sign describes the tone of those patterns, and its house shows the area of life where they play out most visibly with partners, so reading both together tells you what feels familiar in romance and what you are being asked to outgrow. For example, a South Node in Libra in the 7th house often points to someone who defaults to people-pleasing, avoids conflict, and lets the other person set the terms of the relationship — a pattern that feels harmonious on the surface but quietly erodes self-definition. By contrast, a South Node in Aries in the 1st house tends toward self-reliance that keeps partners at arm's length, where independence becomes a wall rather than a strength. Neither placement is a flaw; it is a well-worn route your Venus and Moon energy takes when relating feels uncertain. The house placement sharpens the reading considerably. A South Node in the 5th house can repeat romantic highs and dramatic courtships without staying power, while a South Node in the 11th house may lean on friendship-based partnerships that avoid the vulnerability of true intimacy. When the South Node forms a tight conjunction or square to Venus, the pattern shows up directly in how you give and receive affection; an opposition to Venus often plays out as projecting the missing quality onto a partner. Practically, the Free South Node Calculator gives you the exact sign and house so you can name the pattern instead of repeating it blindly. Pair it with your North Node placement — always directly opposite — to see the direction of growth: if the South Node is Libra in the 7th, the North Node is Aries in the 1st, and the work is learning to want, choose, and assert yourself inside partnership rather than dissolving into it. ## South Node and Career and Purpose The South Node in the natal chart marks the professional skills and status patterns you arrive with — the talents that come easily because you have used them before — while its house placement shows where in your working life those defaults concentrate. Read together, they describe the career comfort zone you can lean on and the specific professional habit you are meant to evolve beyond. A South Node in Capricorn, for instance, brings natural authority, strategic patience, and a talent for structure, but it can also harden into workaholism and a belief that worth must be earned through achievement. A South Node in Cancer points to caregiving, institutional memory, and emotional intelligence in the workplace, with the shadow side being over-identification with a family business, a single employer, or a role defined by who you look after. The sign gives the flavour; the house gives the venue. House placement matters most for career questions. A South Node in the 10th house repeats an established public reputation or inherited professional identity — you may default to the family trade or the title you earned years ago — while the North Node in the 4th house asks you to build something rooted in private meaning instead. A South Node in the 6th house shows mastery of daily systems, service roles, and technical craft, with the growth edge toward the 12th house themes of intuition, retreat, and work done behind the scenes. A South Node in the 2th house (paired with a North Node in the 8th) suggests income patterns you already understand, with the developmental pull toward shared resources, investment, and value systems you do not control alone. Aspects refine the picture: a South Node conjunct Saturn in the 10th intensifies the pull toward established structures and long-earned authority, while a South Node square Jupiter may repeat cycles of overextension and scattered professional ambition. Timing arrives through transits and progressions — when Saturn, Jupiter, or the progressed Sun crosses your South Node, an old career pattern resurfaces for review rather than by accident. The Free South Node Calculator returns your exact sign and house so you can locate that pattern precisely, and reading it alongside your North Node shows the professional direction the chart is pulling you toward. ## South Node and Subconscious Inner Life and Expression The South Node marks the zodiac sign and house where your subconscious already feels fluent — the inherited skills, reflexive habits, and comfort-zone behaviors you arrived with. Because the Moon's South Node sits exactly 180° opposite the North Node, every South Node placement describes what you are releasing while the North Node describes what you are growing toward; the two always share an axis, so a South Node in the 4th house (home, roots, family) automatically places the North Node in the 10th house (career, public standing). Under the hood, the Free South Node Calculator computes the lunar node by mean or true node formula from your birth date, time, and place. The exact birth time refines the house cusp degrees — under Placidus, unequal house sizes shift with latitude, while Whole Sign and Equal House assign cusps differently — and determines whether the South Node falls at the end of one house or the start of the next. If no birth time is supplied, the engine defaults to a solar-noon chart, which keeps the node's sign and its aspect pattern to the Sun, Moon, Mercury, Venus, Mars, Jupiter, Saturn, Uranus, Neptune, Pluto and Chiron accurate even though house placement becomes approximate. Interpretively, the South Node describes the subconscious template: what you do automatically, what feels like talent rather than effort, and what can quietly become a trap when overused. A South Node in Scorpio in the 8th house, for example, brings a natural command of shared resources, crisis, and psychological depth, but can default to control or secrecy; the opposing Taurus 2nd-house North Node asks for simple self-worth and steady material independence instead. Reading the South Node alongside the North Node, then watching how transits, solar arcs, and secondary progressions activate the axis over time, shows when an old pattern is being triggered and when the growth side of the axis is finally within reach. ## South Node in the Twelve Zodiac Signs Your South Node sign shows the specific zodiac flavor of the habits and talents you are releasing, always paired with the North Node sign exactly six signs away. The Free South Node Calculator returns that sign directly from your birth data, then places it in a house so you can see which life area carries the familiar pattern. Each sign gives the comfort zone a distinct texture: - Aries South Node (Libra North Node): instinctive self-assertion and quick action, released to develop compromise, partnership, and the 7th-house art of one-to-one relating. - Taurus South Node (Scorpio North Node): comfort in stability, possessions, and steady pace, released to embrace shared resources, intimacy, and emotional depth in the 8th house. - Gemini South Node (Sagittarius North Node): facility with information, chatter, and multiple small tasks, released to pursue conviction, higher study, and 9th-house meaning. - Cancer South Node (Capricorn North Node): nurturing instinct and family loyalty, released to build public responsibility and 10th-house achievement. - Leo South Node (Aquarius North Node): personal charisma and creative pride, released to join groups, causes, and 11th-house community. - Virgo South Node (Pisces North Node): precision, analysis, and service through improvement, released to allow faith, compassion, and 12th-house surrender. - Libra South Node (Aries North Node): diplomacy and aesthetic harmony, released to claim independent will and 1st-house self-definition. - Scorpio South Node (Taurus North Node): intensity, investigative skill, and control of shared matters, released to build simple worth and 2nd-house self-sufficiency. - Sagittarius South Node (Gemini North Node): broad vision and philosophical certainty, released to value local detail, dialogue, and 3rd-house learning. - Capricorn South Node (Cancer North Node): discipline and institutional mastery, released to soften into home, belonging, and 4th-house roots. - Aquarius South Node (Leo North Node): detachment, systems thinking, and group identity, released to own personal creativity and 5th-house expression. - Pisces South Node (Virgo North Node): empathy, imagination, and boundaryless sensitivity, released to develop craft, routine, and 6th-house daily work. The calculator applies the same node formula regardless of which house system you choose — Placidus, Whole Sign, or Equal House — but the sign itself never changes with house system, only the house number does. Timing arrives through transiting Saturn or the outer planets crossing the South Node degree, solar arcs carrying the progressed Sun to the node axis, or secondary progressions activating the sign's ruler; each of these moments tends to surface the old pattern for conscious review.

Because the lunar nodes always sit exactly 180° apart, the South Node's house is always directly opposite the North Node's house — a South Node in the 4th house of home and roots always pairs with a North Node in the 10th house of career and public standing. The Free South Node Calculator determines this house using your birth time and location: with an exact birth time, house cusps are computed via the Placidus system (or Whole Sign / Equal House if you select them), placing the node precisely within one of the twelve sectors. Without an exact birth time, the tool defaults to a solar-noon chart, which still guarantees accurate sign and aspect readings for the node itself, though house placement may shift by one sector. Here is how each house manifests: - 1st house: Past-life identity and self-image feel familiar; growth comes through partnership (7th house North Node). - 2nd house: Established possessions and self-worth patterns; releasing grip on material security to embrace 8th-house shared resources. - 3rd house: Habitual thinking, siblings, and local routines; moving toward 9th-house philosophy and long-distance travel. - 4th house: Family karma and emotional roots; the soul grows through 10th-house public contribution. - 5th house: Creative ego and romance patterns; evolving through 11th-house community and ideals. - 6th house: Perfectionism in daily work and health; expanding into 12th-house spiritual surrender. - 7th house: Codependency or defined relationship roles; individuating through the 1st-house self. - 8th house: Control over shared assets and intimacy; learning 2nd-house personal values and earned income. - 9th house: Dogmatic beliefs and over-reliance on doctrine; grounding into 3rd-house everyday learning. - 10th house: Status-driven ambition; softening into 4th-house private life and emotional foundation. - 11th house: Group identity and fixed ideals; engaging 5th-house personal creativity. - 12th house: Escapism or unconscious patterns; stepping into 6th-house structured service and routine. Timing activates this potential: transit Saturn squaring your natal South Node, solar arcs moving the Sun toward the node's degree, or secondary progressions igniting the South Node house cusp all mark periods when old patterns surface for release. A conjunction from transit Pluto to the South Node, for example, tends to force a deep purge of the habits tied to that house, while a trine from transit Jupiter can ease the transition by expanding opportunity in the opposite (North Node) house. ## South Node vs North Node The South Node marks what you already know and can release; the North Node marks the unfamiliar growth edge you are moving toward. They are always in opposite signs and opposite houses — a South Node in Scorpio in the 8th house pairs with a North Node in Taurus in the 2nd house — forming a single axis of karmic tension rather than two independent points. The Free South Node Calculator computes both simultaneously from your birth data, since the engine derives one from the other by adding exactly 180° to the ecliptic longitude. The distinction plays out concretely in interpretation. If your South Node is in Capricorn in the 10th house, you carry seasoned competence in career structure, authority, and public responsibility — Saturn-ruled mastery built over time — while your North Node in Cancer in the 4th house asks you to develop emotional nurturing, private life, and family care, areas that feel unpracticed. Conversely, a South Node in Leo in the 5th house shows natural creative flair and romantic magnetism, whereas the North Node in Aquarius in the 11th house pushes toward collective contribution and detachment from personal spotlight. Neither node is "good" or "bad": the South Node is a resource you can draw on, not a flaw to eliminate, and the North Node is a direction, not a guarantee of ease. Aspects color the axis differently. A square from Saturn to either node tends to intensify the tension between the two poles, requiring disciplined effort to move toward the North Node. A trine from Venus to the North Node can make the growth path feel pleasurable and socially supported, while a conjunction of Mars to the South Node may amplify impulsive old habits that need conscious redirection. Transits and progressions activate the axis over time — a solar arc Sun approaching conjunction with your North Node often coincides with a period of heightened visibility in the life area of its house, whereas the same arc hitting the South Node can signal a closing chapter in the familiar territory. For a deeper reading of both nodes together, explore the full tool at [YesAstrology Tools](https://www.yesastrology.com/en/tools). ## How Accurate Is a South Node Calculator? A South Node calculator is astronomically precise: the lunar nodes are mathematical points where the Moon's orbit crosses the ecliptic, so their sign and degree can be computed to within minutes of arc from your birth date, time, and place. The South Node's sign is always exactly opposite the North Node — if the North Node sits at 14° Taurus, the South Node is at 14° Scorpio — and this opposition is fixed by geometry, not interpretation. What varies between calculation methods is house placement, not sign accuracy. The engine behind this tool computes node placement from ephemeris data tied to your birth moment. Because the nodes move through a sign in roughly 18 months, a birth date alone usually fixes the sign correctly; the exact birth time refines the degree and determines which house cusp the South Node falls in. Without an exact time, the tool defaults to a solar-noon chart, which preserves sign accuracy and planetary aspects but leaves house placement approximate — the South Node could shift one house either way depending on the true birth hour. House systems also differ. Placidus produces unequal houses that vary with latitude and can leave a house intercepted, while Whole Sign assigns each house exactly one zodiac sign starting from the Ascendant, and Equal House measures every cusp at the same degree as the Ascendant. If your South Node sits near a cusp at 0° or 29° of a sign, Placidus and Whole Sign may disagree about the house. For example, a South Node at 28° Virgo could fall in the 11th house under Placidus but the 12th under Whole Sign at certain latitudes. When this happens, read both houses — the sign itself never changes. Timing techniques layer on top of this static position. Transits of Saturn, Uranus, or Pluto across your natal South Node activate its themes during specific periods, while secondary progressions and solar arcs move the progressed South Node about one degree per year, slowly reshaping which life area the node emphasizes. The natal calculation is exact; the timing of when its patterns surface depends on which of these cycles you are tracking. ## Practical Advice and Next Steps for Your South Node Start by noting your South Node's sign and house, then read them together: the sign describes the ingrained habit you default to, and the house shows the life area where that habit plays out most automatically. A South Node in Capricorn in the 10th house, for instance, points to over-reliance on achievement and public status as a coping mechanism, while the same Capricorn South Node in the 4th house would manifest as clinging to family roles or familiar domestic structures instead. Next, locate the North Node — always the exact opposite point — to see the direction of growth. If your South Node is in Scorpio in the 8th house (shared resources, intimacy, control), your North Node sits in Taurus in the 2nd house (personal income, self-worth, tangible assets). The practical move is to notice moments when you grab for control in partnerships and consciously redirect toward building your own stability. Journaling these episodes for a lunar cycle makes the pattern visible. Then check which natal planets aspect the South Node. A conjunction with Saturn adds a layer of duty or fear around releasing the old pattern; a square from Mars suggests the comfort zone is defended aggressively; a trine from Neptune makes the familiar territory feel pleasantly blurred and harder to leave. These aspect dynamics tell you how much friction to expect when you step away from the habit. Finally, watch the timing. When transiting Saturn or Pluto makes a conjunction, opposition, or square to your natal South Node, the old pattern tends to be tested or stripped away — often through circumstance rather than choice. Progressed lunar cycles (roughly every 27 days) and solar arc activations of the node offer softer, more reflective windows. Record these dates alongside your natal placement so you can anticipate rather than react.

The South Node is the point where the Moon's orbit crosses the ecliptic, sitting exactly opposite the North Node. In a birth chart it describes familiar patterns, inherited habits and natural talents you already carry, often described as a karmic comfort zone. ### How does a South Node calculator work? A South Node calculator uses your birth date, time and location to compute the Moon's nodes from astronomical positions, then reports the zodiac sign and house the South Node occupies in your chart. ### What do I need to calculate my South Node? You need your date of birth, your exact birth time and your birthplace. The birth time matters because it determines which house the South Node falls in, while the date and place fix the zodiac sign. ### Is the South Node calculator free to use? Yes. The Free South Node Calculator on YesAstrology gives you your South Node sign and house placement at no cost, with results available as soon as you enter your birth details. ### What does my South Node sign mean? Your South Node sign shows the qualities and coping strategies that come naturally to you, often so familiar that you rely on them without thinking. The sign describes what you may need to soften or release in order to grow toward your North Node. ### What does my South Node house mean? The house placement points to the area of life where your oldest patterns show up most clearly, such as relationships, work or inner life. It tells you where the comfort zone is strongest and where releasing old habits matters most. ### What is the difference between the South Node and the North Node? The two nodes always sit opposite each other in the chart. The South Node describes what is already known and well practised, while the North Node points toward the unfamiliar qualities and direction of growth you are moving into. ### How accurate is a South Node calculator? Accuracy depends on the precision of your birth data. With an exact birth time and place, the calculator can determine the South Node sign and house reliably; without a birth time, the sign remains accurate but the house placement cannot be fixed. ### Can the South Node tell me about past lives? Many astrologers read the South Node as a signature of past-life or inherited patterns, describing instincts and habits carried into this life. It is best used as a practical map of familiar tendencies rather than a literal historical record. ### How do I interpret my South Node in love and career? In love, the South Node shows the roles and dynamics you slip into easily with partners, while in career it highlights skills you already master and may over-rely on. Reading both against the North Node shows where new behaviour would serve you better. ## Explore more - [Age Calculator](https://www.yesastrology.com/en/tools/analysis-calculators/age-calculator): Calculate your exact age in years, months and days, plus astrological milestones and upcoming Saturn and Jupiter return dates.
