What Star Sign Am I? Find Your Star Sign by Date

Your star sign is whichever of the twelve zodiac signs the Sun occupied on the day you were born. The term "star sign" and "sun sign" mean the same thing — most people use them interchangeably. Below are the dates for all twelve signs, followed by specific lookups for the dates people ask about most often.

Star Sign Dates: All 12 Signs

• Aries ♈︎ March 21 – April 19 · cardinal fire · ruled by Mars
• Taurus ♉︎ April 20 – May 20 · fixed earth · ruled by Venus
• Gemini ♊︎ May 21 – June 20 · mutable air · ruled by Mercury
• Cancer ♋︎ June 21 – July 22 · cardinal water · ruled by Moon
• Leo ♌︎ July 23 – August 22 · fixed fire · ruled by Sun
• Virgo ♍︎ August 23 – September 22 · mutable earth · ruled by Mercury
• Libra ♎︎ September 23 – October 22 · cardinal air · ruled by Venus
• Scorpio ♏︎ October 23 – November 21 · fixed water · ruled by Pluto (classical: Mars)
• Sagittarius ♐︎ November 22 – December 21 · mutable fire · ruled by Jupiter
• Capricorn ♑︎ December 22 – January 19 · cardinal earth · ruled by Saturn
• Aquarius ♒︎ January 20 – February 18 · fixed air · ruled by Uranus (classical: Saturn)

Find your birthday in the list. That is your star sign. What follows covers how the system works and provides detailed lookups for specific dates.

How Star Signs Are Determined

The Western tropical zodiac divides the ecliptic — the Sun's apparent annual path through the sky — into twelve equal 30-degree arcs. The year begins at the vernal equinox (around March 20–21) with Aries and proceeds through all twelve signs in sequence.

Your star sign is whichever arc the Sun was passing through when you were born. The boundaries remain consistent year to year. Some sources list slightly different transition dates because the Sun's crossing from one sign to the next shifts by a few hours annually. The ranges above are correct for the vast majority of birthdays. If yours falls on an exact transition day, a chart calculated from your precise birth time will settle it.

The terms "star sign," "sun sign," and "zodiac sign" all refer to the same placement. Different countries and traditions use different terms — "star sign" is more common in British and Australian English, while "zodiac sign" or "sun sign" is more common in American usage. They all point to the same thing: the Sun's position in the zodiac at birth.

10th June Star Sign: Gemini

June 10 falls in Gemini — the mutable air sign ruled by Mercury. Gemini runs from May 21 through June 20, placing June 10 solidly in the middle of the sign with no boundary question.

Mercury rules Gemini through speed and range rather than depth: the capacity to pick up new material rapidly, hold several conversations simultaneously, and make lateral connections between subjects that appear unrelated. The mutable modality gives Gemini its adaptive quality — it reads the room and adjusts its approach without losing its own position.

The air element means Gemini operates primarily through thought and language. People born on June 10 tend to process the world verbally — talking through problems, writing to think, asking questions as a form of understanding rather than challenge. The sign's reputation for surface-level thinking is a misread of what is actually breadth: Gemini covers more ground than the fixed signs and does it faster, which looks like restlessness from the outside but functions as genuine intellectual range from the inside.

11 January Star Sign: Capricorn

January 11 falls in Capricorn — the cardinal earth sign ruled by Saturn. Capricorn runs from December 22 through January 19, placing January 11 past the midpoint of the sign and well clear of both boundaries.

Saturn as ruler gives Capricorn its structural quality: an orientation toward building things that hold over time, a willingness to accept delayed returns, and a natural understanding that the most valuable outcomes require sustained effort rather than a single inspired moment. The cardinal modality means Capricorn initiates — but unlike Aries's impulsive starts, Capricorn's initiations tend to arrive with a plan already half-formed.

The earth element keeps Capricorn practical. People born on January 11 are not theorists by default — they want to see the thing built, measured, and working. Their patience is not passive. It is the patience of someone who has calculated how long the project will take and is willing to stay that long.

17th June Star Sign: Gemini

June 17 falls in Gemini — three days before the sign ends and Cancer begins on June 21. Despite the proximity to the boundary, June 17 is unambiguously Gemini. The Sun has not yet crossed into the next sign.

Late-degree Gemini carries the full mutable air signature. Some astrologers note that the final degrees of any sign carry a quality of completion — the sign's themes reaching their most developed expression before the energy shifts. Whether or not you find that framework useful, the structural fact is simple: June 17 is Gemini, not Cancer, not a blend of both.

Gemini's defining quality is the ability to hold contradictory ideas without forcing premature resolution. Mercury's rulership shows up as verbal fluency and quick pattern recognition. People born on June 17 carry these qualities fully — the sign does not weaken as it approaches its boundary. A Gemini born on May 22 and a Gemini born on June 17 share the same sun-sign placement.

18 March Star Sign: Pisces

March 18 falls in Pisces — the mutable water sign ruled by Neptune (modern system) and Jupiter (classical). Pisces runs from February 19 through March 20, placing March 18 just two days before the sign ends and Aries begins at the vernal equinox.

Despite sitting near the boundary, March 18 is Pisces without qualification. The Sun does not begin blending with the next sign as it approaches the transition — it is in one sign or the other at any given moment.

Pisces is the twelfth and final sign of the zodiac year. Its defining quality is perceptual range: an awareness of emotional undercurrents, atmospheric shifts, and unspoken dynamics that operates below the threshold of deliberate analysis. The mutable modality makes Pisces adaptive — it moves with what it encounters rather than forcing circumstances into a predetermined shape. The water element gives the sign its emotional depth and intuitive accuracy.

People born on March 18 carry the late-Pisces signature at full strength. The proximity to the Aries boundary does not dilute the placement.

Star Sign vs. Full Birth Chart

Your star sign tells you one thing: which 30-degree arc of the ecliptic the Sun occupied at birth. It is the most commonly known placement in Western astrology, and it describes core temperament — but it is not the whole picture.

A full birth chart includes your Moon sign (how you process emotion), your rising sign (how you present to others and how the world registers you first), Mercury (communication style), Venus (values and relational patterns), and Mars (drive and decisional style). These placements often fall in different signs from your Sun, which is why people sometimes feel their star sign description fits only partially.

Beyond Western astrology, other traditions read the same birth data through different frameworks entirely. BaZi (Chinese astrology) maps your date and time to Five Elements across Four Pillars. Numerology reduces the date to structural numbers. Each system reads a different layer of the same information.
