Capricorn: zodiac sign, dates, traits, compatibility

Capricorn in astrology: dates, typical traits, ruler Saturn, compatibility, Capricorn Sun, Moon and Rising. The full guide to the cardinal Earth sign.

16 min read · Updated 2026-06-11

Capricorn is the tenth sign of the tropical zodiac. It lines up with the winter solstice, the longest night of the year, the exact moment when the light begins its slow climb back. Tradition ties it to patient construction, to disciplined ambition, to the capacity to climb for a long time without complaining. This page covers Capricorn in detail: its dates, its astronomical placement, its element, its planetary ruler Saturn, the symbolism of the goat-fish, its archetypal traits, and how to read it depending on whether Capricorn is your Sun, your Moon or your Rising sign. You will also find a section on Capricorn compatibility, the tropical versus sidereal question, and a FAQ.

Capricorn dates: 22 December to 19 January (tropical)

In tropical astrology, the Sun enters Capricorn at the winter solstice, around 22 December, and leaves it around 19 January. The exact dates vary a little from one year to the next, depending on leap years and orbital mechanics. For 2026, the Sun enters Capricorn on 22 December 2025 at 03:03 UTC and leaves it on 20 January 2026 at 13:44 UTC (approximate times).

Being born inside that window means you have a Capricorn Sun sign. But as with every sign, the Sun sign is only one piece of the puzzle: a Capricorn Moon, a Capricorn Rising, or several planets in Capricorn in the chart matter just as much, if not more.

The overlap with the winter solstice is no small thing symbolically. Capricorn begins when the Sun is at its lowest in the sky, and right then it starts to climb again. Tradition links this archetype to the idea of a patient climb back up from the bottom: nothing is given, yet each day lengthens a little, imperceptibly.

⚠️ Note: if you use a sidereal system (Indian astrology, or some Western astrologers), the dates differ. The Sun enters sidereal Capricorn about 24 days later, around 14 January. That gap is explained in Tropical vs sidereal.

Capricorn in the sky: astronomical placement

The constellation Capricornus is a faint figure of the southern sky, wedged between Aquarius to the east and Sagittarius to the west, in a region the Babylonians called "the sea" (an area full of watery constellations). Its main star, Deneb Algedi (delta Capricorni), is magnitude 2.8: visible to the naked eye under a clear sky, with no special brightness.

Its shape is often described as a flattened triangle, sometimes a "bicorne hat". Hard to spot unless you know exactly where to look. That lack of obviousness in the sky fits the archetype rather well: discreet, functional, not there to be seen first.

The glyph ♑ is a complex loop whose reading varies by source. People see the horns of the goat above the tail of a fish, the hybrid animal Capricornus. Some read it as the knot of a rope or a fishhook.

In tropical astrology, Capricorn occupies the sector from 270° to 300° of the zodiac, measured from the vernal point. The full geometry is in The astrological sky: the astronomical basics.

Element, mode, polarity: the signature of Capricorn

Every sign carries a combination of three attributes that form its signature.

Earth: the element

Capricorn is an Earth sign, like Taurus and Virgo. The Earth signs are tied to matter, to the concrete, the tangible, the lasting. Where Fire flares up and Air circulates, Earth builds and stabilizes. A chart dense in Earth leans toward measurable results, solid structures, foundations that hold over time.

Each Earth sign has its own tone. Taurus embodies sensual, pleasure-loving Earth, the delight of materials, of the body, of what nourishes. Virgo embodies analytical, functional Earth, the sorting, the efficiency, the service. Capricorn embodies ambitious, time-bound Earth: building over the long term, the methodical ascent, raising up a body of work that outlasts the individual.

Cardinal: the mode

Capricorn is a cardinal sign, like Aries, Cancer and Libra. Cardinal signs mark the start of a season and are linked to initiative, to the opening of new cycles.

Where Aries initiates through momentum and impulse, Capricorn initiates through structured decision: heading set, plan laid out, the climb begun. Fixed signs consolidate, mutable signs transform. Capricorn, for its part, lays the first stones of a construction whose finished form it has already imagined.

Negative / yin: the polarity

Capricorn is a sign of negative polarity (or yin, nocturnal in classical terms: these labels are symbolic, neither belittling nor gendered). Its energy is receptive and inward rather than emitting and extroverted. Capricorn acts, but inward: toward building its own structure, toward patient accumulation, toward consolidation more than projection.

That is consistent with its link to Saturn and to the 10th house: an energy pulled upward (ambition, ascent), but by the longest, most solid road.

Saturn: the planetary ruler of Capricorn

The planetary ruler of Capricorn is Saturn. That is, Saturn is "at home" in this sign: its principles of structure, limit, responsibility and the long view express themselves here most directly.

Saturn is the planet of passing time, of the deadlines that shape things, of the constraints that reveal how solid what you build really is. Its cycle of ~29.5 years around the Sun gives it a particular place in life's great cycles (the famous "Saturn return" around 29 to 30, then again around 58 to 60). Where other planets give fast and take back, Saturn gives slowly. What it gives holds.

The full page: Saturn in astrology.

In classical astrology, before Uranus, Saturn also ruled Aquarius. Capricorn and Aquarius therefore share a Saturnian kinship, but with two very different expressions. Capricorn embodies Saturn in its institutional, vertical dimension (hierarchy, career, authority); Aquarius in its systemic, horizontal dimension (social structure, law, the collective).

The natural house of Capricorn is the 10th house: the house of vocation, public status, career, the Midheaven (MC). It is the highest house of the chart, symbolically what you build toward the eyes of the world.

Mythological symbolism of Capricorn

The figure of Capricornus (the goat with a fish's tail) is one of the oldest and strangest in the zodiac. Several mythologies overlap here.

Pan and the Nile. The best-known Greek version: the god Pan, to escape the monster Typhon, throws himself into the Nile and tries to turn into a fish. The transformation is only partial. The upper half stays goat, the lower half becomes fish. Zeus, amused or moved, fixes this hybrid image among the stars. The story reads as the idea of an urgent, imperfect transformation, a sign that lives between two worlds.

Amalthea. In another tradition, Capricornus is Amalthea, the divine goat who fed the infant Zeus hidden away in Crete. Her horn, broken by accident, becomes the cornucopia (the horn of plenty). Tradition links this figure to the idea that Capricorn, by giving without counting the cost (by feeding, building, serving), becomes a source of abundance itself.

The mountain goat. Beyond the myths, the figure most directly legible in the archetype is the mountain goat, the animal that climbs near-vertical rock faces, not fast, with no particular grace, but with a precision and endurance no other animal can match. It does not go down. It goes up.

This composite symbolism gives Capricorn its particular tone: an ambition rooted in discipline, the ability to advance in hard conditions, a hybrid nature stretched between the depths (the fish's tail, the discreet emotional world) and the height it aims for.

Archetypal traits of Capricorn

These characteristics describe the archetype, not a real person. A real Capricorn chart is modulated by the Moon, the Rising, the aspects. These traits are a reading lens.

Archetypal strengths

• Structured ambition: sets long-term goals and builds the path step by step, without scattering.
• Discipline: able to work with no visible immediate result, to last the distance without burning out.
• Sense of responsibility: takes seriously what it undertakes, owns the consequences of its decisions.
• Realism: sees things as they are, not as it would like them to be. Useful in a crisis.
• Reliability: says what it does, does what it says, even when it is hard.
• Natural authority: inspires trust through demonstrated competence, not through talk.
• Long-term planning: thinks in years and decades where others think in weeks.
• Endurance: keeps going where others give up. Fatigue alone is not enough to stop it.
• Integrity: uneasy with the easy shortcut, with compromise of principle.

Friction points

• Rigidity: can cling to structures or methods that no longer work, out of fear of chaos.
• Baseline pessimism: a tendency to see the obstacles first, the risks, what could go wrong.
• Apparent coldness: the economy of warmth reads as a lack of empathy to those who need it shown.
• Workaholism: can define itself entirely by work, sacrificing the rest without noticing.
• Excessive control: trouble delegating, letting go, admitting it did not foresee everything.
• Harshness toward the self: the standards apply to the self first. A personal mistake goes down badly, and a sense of never doing enough can set in.
• Relationship to status: a risk of confusing "succeeding" with "being recognized as having succeeded", which opens the door to a hollow social ambition.

These friction points are not fated. A worked-on Capricorn archetype can turn rigidity into steadiness, pessimism into realistic vision, coldness into respectful discretion, workaholism into an exceptional capacity to build.

Capricorn as Sun, Moon, Rising

Capricorn does not mean the same thing depending on which planet sits in it in the chart.

Sun in Capricorn (~22 December to 19 January)

This is the classic "Sun sign" reading: your conscious identity, what you are trying to become, what gives you the sense of being fully alive.

Sun in Capricorn builds its sense of self through what it accomplishes. The identity lives not in raw being but in the structure: what you have built, the proofs of competence, the status earned. A Sun-Capricorn person who is not moving forward can feel a diffuse discomfort, a sense of wasting time. Maturity is not an obstacle here: many Capricorns "age backward", more relaxed and more luminous past forty than they were at twenty.

In traditional terms, Sun in Capricorn is an effective placement: Saturn, ruler of the sign, is linked to the long view and to durable construction. The solar expression asks for patience to unfold, but what gets built holds.

Moon in Capricorn (~2.5 days a month)

The Moon describes your emotional world, what feeds you inwardly, what makes you feel safe.

The Moon in Capricorn is considered to be in fall in the tradition (Cancer, the opposite sign, is its domicile). In practice, emotional needs and the lunar register (affective spontaneity, the need to be fed and carried) express themselves with difficulty in a sign oriented toward mastery and restraint.

The Moon in Capricorn holds emotions in, structures them, controls them. Security is not in tenderness received but in mastery of its situation: projects moving forward, a clear plan, chaos kept at arm's length. Comfort comes through competence, through doing the job well rather than being consoled. A real risk: unintegrated emotions that surface late and hard, trouble asking for help.

This is not a "bad placement". It is a placement that calls for conscious work on giving emotion permission.

Capricorn Rising (varies with the time of birth)

The Rising sign is the sign that was coming up on the eastern horizon at the moment of your birth. It describes your physical presence, the first impression you give, your style of walking into a room.

Capricorn Rising gives a serious bearing, a structured look, an "older than their years" air in youth. Others first pick up the restraint, the competence, sometimes a certain distance. Then something loosens with time. Tradition says the Capricorn Rising "grows younger" with age, as if the gravity of the first decades eventually turned into a lightness earned (and this is one of the more convincing formulas of Capricorn symbolism).

With a Capricorn Rising, your chart ruler is Saturn: where Saturn sits in your chart (in which sign, which house, with which aspects) becomes decisive for reading how you present to the world and your life path.

For the mechanics of the Rising sign, see The angles: Rising, MC, Descendant, IC.

Capricorn compatibility: who clicks, who grates?

Astrological compatibility is a big subject. Every chart is unique, and "sign-to-sign compatibility" is a simplification. At the scale of the archetype, some combinations really do run smoother or more stimulating.

Signs in trine (~120°: smooth)

Trine means the same element. Capricorn (Earth) is in trine with:

• Taurus: shares the feel for the concrete, the taste for durability, the sensory relationship to matter. A stable, reliable duo, sometimes too settled into routine.
• Virgo: shares the high standards, the analysis, the care for detail. A functional couple, very able to build together, as long as they don't get lost in perfectionism.

Opposite sign (180°: attraction and complementarity)

• Cancer: the opposite on the career/home axis. Capricorn builds upward (vocation, status, the public world); Cancer builds inward (family, intimacy, roots). A deep complementary axis: Capricorn learns tenderness and emotional rootedness from Cancer; Cancer learns structure and the capacity to deliver from Capricorn. Frequent tension around time (Capricorn working too much, Cancer waiting).

Signs in square (~90°: productive tension)

• Aries: another cardinal sign, Fire. Aries improvises, Capricorn plans. One wants immediate results, the other thinks in decades. A tense collaboration, but often productive.
• Libra: another cardinal sign, Air. Libra seeks harmony, the beautiful; Capricorn seeks efficiency, the solid result. Friction over values and pace, real complementarity on the social axis.

Signs in sextile (~60°: gentle support)

• Scorpio (Water): a shared depth, the ability to get through hardship together, a serious relationship to transformation.
• Pisces (Water): Capricorn structures what Pisces imagines; Pisces brings Capricorn the inner dimension it tends to neglect.

Other pairings

• Capricorn/Capricorn: a duo of formidable efficiency. Risk: emotions left out entirely.
• Sagittarius/Capricorn: different paces (freedom vs structure), but a possible complementarity between vision and execution.
• Capricorn/Aquarius: co-Saturnian, a deep kinship, opposite expressions. One builds the hierarchy, the other questions it.
• Capricorn/Leo: shared ambition, but Leo wants to be seen and admired where Capricorn wants to be recognized for what it does.

Capricorn season in transit

When the Sun enters Capricorn (around 22 December), it is Capricorn season for everyone. Tradition links it to a phase of taking stock, of reassessing structures, of taking on responsibility before the new civil year begins.

Symbolically it is the time of year when the light is at its lowest but starting to come back: an invitation to assess honestly what you have built, to decide what you want to build from there. Transits of Saturn through Capricorn reinforce these questions of long-term structure. See Saturn in astrology.

Tropical vs sidereal: your sign can change

If you use a sidereal system (Indian astrology, for instance), your sign may be different. Someone born on 1 January is:

• Sun in Capricorn in tropical (around 11° Capricorn).
• Sun in Sagittarius in sidereal (with a roughly 24° shift, depending on the ayanamsha used).

Neither one is "the real one". They are two different symbolic systems, starting from different premises: a moving equinox vs fixed constellations. The technical detail is in Tropical vs sidereal.

Astrolabica lets you switch between the two in its interactive chart so you can see that shift in concrete terms.
