Gemini dates in 2027: Friday, May 21, to Sunday, June 20, Eastern Time. The Sun enters Gemini at 2:18 a.m. EDT on May 21 and Cancer at the June solstice, 10:11 a.m. EDT on Monday, June 21.
The Gemini zodiac sign covers the third 30 degrees of the ecliptic, from 60° to 90° of celestial longitude, and it always ends at the June solstice.
In 2027, Gemini begins on Friday, May 21, in Eastern, Central, and Mountain Time, but on Thursday, May 20, in Pacific Time, Alaska, and Hawaii, because the Sun crosses 60° at 06:18 UTC.
In 2024, 2025, and 2026, Gemini began on May 20 everywhere in the United States, so the sign of a May 20 birthday depends on the year.
Gemini is also one of the two longest tropical signs, lasting 31 days and almost 8 hours.
This page gives the exact 2027 start and end times in every US time zone, the dates for 2024 through 2030, and the federal holidays that fall in Gemini season.
It also compares the Western sign with Vedic Mithuna and with the Gemini constellation.

Gemini zodiac sign dates that differ by location
The start of Gemini 2027 falls 18 minutes after midnight in Mountain Time, so it lands on different dates across US time zones. These are the boundaries that matter for US births in 2027:
- Thursday, May 20: in Pacific Time, a birth at or after 11:18 p.m. PDT is a Gemini; the cutoff is 10:18 p.m. AKDT in Alaska and 8:18 p.m. HST in Hawaii. In Eastern, Central, and Mountain Time, all of May 20 is Taurus.
- Friday, May 21: in Eastern Time, a birth before 2:18 a.m. EDT is a Taurus; in Mountain Time, the cutoff is 12:18 a.m. MDT.
- Monday, June 21: a birth before 10:11 a.m. EDT (7:11 a.m. PDT) is a Gemini; a birth at or after that moment is a Cancer.
The neighbouring signs are covered in Taurus Zodiac Sign and Cancer Zodiac Sign.

Why Gemini season is longer than most signs
Gemini season runs longer than most signs because Earth moves more slowly as it approaches aphelion, its farthest point from the Sun, in early July.
Every tropical sign spans exactly 30 degrees, but the Sun’s apparent motion along the ecliptic slows during the Northern Hemisphere summer.
From 2024 to 2027, Gemini lasted between 31 days, 7 hours, 48 minutes and 31 days, 7 hours, 53 minutes, nearly a full day longer than Aries. Only Cancer, which spans aphelion, runs longer.
How to check whether a birthday is Gemini
Use this method for a birth date of May 20, 21 or 22, or June 20 or 21:
- Find that year’s Gemini start or end time in the tables above and convert it to UTC.
- Convert the birth time to UTC, accounting for daylight saving time at the birthplace.
- A birth at or after the start time and before the end time is Gemini.
Holidays and observances during Gemini season 2027

Gemini birthdays in 2027 span two birthstone months, May and June; the June stones are covered on June Birthstone.
What is the Gemini zodiac sign?
The Gemini zodiac sign is the segment of the ecliptic from 60° to 90° of celestial longitude, the third of 12 equal sectors measured from the March equinox.
Its end point, 90°, is the June solstice, when the Sun reaches its farthest point north of the celestial equator.
Western astrology assigns Gemini the attributes below.
| Attribute | Gemini |
|---|---|
| Position | 3rd of 12 signs; ecliptic longitude 60°–90° |
| Symbol | ♊ the twins |
| Element | Air, shared with Libra and Aquarius |
| Modality | Mutable, shared with Virgo, Sagittarius and Pisces |
| Ruling planet | Mercury |
| Exaltation | North Node (some modern authors add Ceres) |
| Detriment | Jupiter |
| Fall | South Node (modern) |
| Opposite sign | Sagittarius |
| Sanskrit name | Mithuna |
The twins are Castor and Pollux of Greek myth, sons of Leda by different fathers: Pollux by Zeus and Castor by Tyndareus, king of Sparta.
When the mortal Castor died, Pollux asked Zeus to share his immortality with his brother, and the pair were placed together in the sky. In astrological tradition, Gemini is associated with curiosity, adaptability, and communication.
These are astrological attributions, not findings of psychological research.
Gemini in Vedic astrology: Mithuna
Vedic (Jyotish) astrology uses the sidereal zodiac, so its Gemini, called Mithuna, starts about 25 days after the Western sign.
In 2027, the Sun enters sidereal Gemini on Tuesday, June 15, at 9:30 a.m. EDT (7:00 p.m. IST). The 5-minute gap reflects different ayanamsa values; the ayanamsa is the offset each system uses between the tropical and sidereal zodiacs.
This moment is called Mithuna Sankranti. Sidereal Gemini ends when the Sun enters Karka (sidereal Cancer) on Friday, July 16, 2027, at 8:22 p.m. EDT, which is 5:52 a.m. IST on Saturday, July 17.
As a result, a person born in Eastern Time between Friday, May 21, and the morning of Tuesday, June 15, 2027, is a Gemini in Western astrology and a Taurus (Vrishabha) in Vedic astrology.
Only births from 9:30 a.m. EDT on June 15 to 10:11 a.m. EDT on Monday, June 21, are Gemini in both systems.
The Gemini constellation
The Gemini constellation is separate from the Gemini sign. It ranks 30th of the 88 constellations by area, covering 514 square degrees, according to Wikipedia’s constellation entry. These are its best-known features:
- Pollux (Beta Geminorum): an orange giant of magnitude 1.14, 34 light-years away, and the brighter of the twin stars.
- Castor (Alpha Geminorum): a sextuple star system 52 light-years away that appears as a single star of magnitude 1.6. It carries the Alpha label despite being fainter because Johann Bayer did not rank the two by brightness in 1603.
- Two planet discoveries: William Herschel found Uranus near Eta Geminorum on March 13, 1781, and Clyde Tombaugh found Pluto in 1930 on photographic plates centred on Delta Geminorum.
- The Geminids: a meteor shower that radiates from Gemini and peaks on December 13–14 at about 100 meteors per hour.
The Sun passes in front of the Gemini constellation from about June 21 to July 20, for 29 days, based on EarthSky’s table of constellation entry dates.
The Sun therefore sits among the stars of Gemini during most of Western Cancer season, not Gemini season. Gemini is best seen in the evening sky in winter, the opposite season to its zodiac dates.
What Gemini is not
Three different things share the name Gemini, and their 2027 dates do not match. The table below compares them.
| Feature | Gemini zodiac sign (tropical) | Mithuna (sidereal Gemini) | Gemini constellation |
|---|---|---|---|
| Used by | Western astrology | Vedic astrology, Hindu calendars | Astronomy |
| Defined by | 60° to 90° from the March equinox | Fixed stars, with an ayanamsa | IAU constellation boundaries |
| Length | About 31 days, 8 hours | About 31 days, 11 hours | About 29 days |
| 2027 start (Eastern Time) | Friday, May 21 | Tuesday, June 15 | About June 21 |
| 2027 end (Eastern Time) | Sunday, June 20 | Friday, July 16 | About July 20 |
Gemini season is also unrelated to the Geminid meteor shower, which peaks in mid-December, when the Sun is in Sagittarius.
Nor is Gemini a late-spring sign everywhere. In the Southern Hemisphere, Gemini season covers late autumn and ends at the start of winter.
Frequently asked questions
What are the Gemini dates?
The Gemini dates in 2027 are Friday, May 21, to Sunday, June 20, in US Eastern Time. Gemini begins at 2:18 a.m. EDT on May 21 and ends at the June solstice, 10:11 a.m. EDT on Monday, June 21, when the Sun enters Cancer. In Pacific Time, Alaska and Hawaii, Gemini 2027 begins on the evening of Thursday, May 20.
Is May 20 Taurus or Gemini?
May 20 is Taurus in most of the United States in 2027 but was Gemini from the moment of the ingress in 2024, 2025, and 2026. In 2027, Gemini begins at 2:18 a.m. EDT on Friday, May 21, so all of May 20 is Taurus in Eastern, Central, and Mountain Time. In Pacific Time, a birth at or after 11:18 p.m. PDT on May 20 is a Gemini.
Is June 21 Gemini or Cancer?
June 21, 2027, is split between Gemini and Cancer. The Sun enters Cancer at the June solstice, 10:11 a.m. EDT (7:11 a.m. PDT) on Monday, June 21, 2027, so births before that time are Gemini and births at or after it are Cancer. In 2024 and 2025, the solstice fell on June 20, making all of June 21 Cancer.
Why does Gemini end on the summer solstice?
Gemini ends on the June solstice because the solstice is the moment the Sun reaches 90 degrees of ecliptic longitude, the boundary between Gemini and Cancer. The tropical zodiac is built on the equinoxes and solstices, so Aries, Cancer, Libra, and Capricorn each begin at one of those four events. In 2027, the June solstice falls at 14:11 UTC on Monday, June 21.
What is the Gemini symbol?
The Gemini symbol is the twins, written with the glyph ♊, two upright strokes joined at the top and bottom. The twins are Castor and Pollux of Greek mythology, who share a single place in the sky. Gemini is an air sign with mutable modality, and its traditional ruling planet is Mercury, according to standard Western astrological references.
When is Mithuna Sankranti in 2027?
Mithuna Sankranti 2027 falls on Tuesday, June 15, 2027, at 7:00 p.m. IST, which is 9:30 a.m. EDT, according to Drik Panchang. It marks the Sun’s entry into sidereal Gemini in the Hindu calendar. AAPS lists the same event at 6:55 p.m. IST. Sidereal Gemini lasts until Karka Sankranti on Friday, July 16, 2027, at 8:22 p.m. EDT.
