If Taurus season was one album on repeat, Gemini season is shuffle. The Sun moves into the mutable air sign in late May, and the mood astrologers describe is quick, social, curious and slightly scattered.

Gemini is ruled by Mercury, the planet of words, messages, travel and trade. The twins in its symbol are Castor and Pollux from Greek myth, brothers so close they shared immortality between them. That is why the sign gets linked to siblings, neighbours, conversations and seeing two sides of everything.

In the northern hemisphere this is late spring turning into summer, the longest light of the year arriving at the very end of the season. In the south it is early winter. In 2027 Mercury itself stations retrograde during Gemini season, from Cancer back toward Gemini. Astrologers find that kind of thing very funny.

The sky behind it

The Sun enters Gemini at May 21, 2027 · 06:18 UTC. At that instant the Moon is full in Sagittarius (99% lit) and the Sun's declination is 20.15°.

The dates

When does Gemini season start and end in 2027?

31 days of the twins, from May 21 to Jun 21.Urania's Mirror, London 1824 · Library of Congress

The Sun crosses 0° Gemini at May 21, 2027 · 06:18 UTC and 0° Cancer at Jun 21, 2027 · 14:11 UTC, 21 hours longer than an average sign.

The date itself splits: Los Angeles is still on May 20 while Sydney has reached May 21. Your zone is in the clock below.

Decans: Jupiter rules the first ten degrees from May 21, Mars takes over on May 31, Sun on Jun 11. The Sun is at 15°, dead centre, on Jun 5, 2027.

  • Keep a list of every idea you have this season, then pick one in Cancer season.
  • Call instead of texting once a week.

Air signs think and talk. Mutable signs adapt and close out a season. Gemini sits at the end of spring in the north, when everything has bloomed and is about to tip into summer. The feel is restless and lively.

The good side is curiosity, wit and the ability to learn fast. The tricky side is spreading yourself thin. If you find yourself starting six things, astrologers would suggest finishing one before the season ends.

With Mercury retrograde arriving partway through, the usual advice applies: reread, double check plans, expect a few crossed wires. It is a good month to revisit old ideas, notes and conversations instead of forcing brand new ones.

The sky this season

Mercury turns retrograde in Gemini season 2027

Johann Bayer, Uranometria, 1603

Moons. New moon on Jun 4, 2027 at 13°58′ Gemini. Full moon on Jun 19, 2027 at 27°33′ Sagittarius. Intention-setters will want Jun 4.

Stations. Mercury turns retrograde on Jun 10, 2027 at 6°22′ Cancer.

Sign changes. Mercury enters Cancer on May 28, 2027. Venus enters Gemini on Jun 8, 2027.

Company. Mercury, Venus and Uranus share Gemini with the Sun (Uranus for all 31 days).

The the twins in the stars

Brothers who shared one immortality

Castor and Pollux were twins with different fathers in the Greek story. Pollux was a son of Zeus and immortal; Castor was the son of a mortal king and could die. When Castor was killed, Pollux begged not to outlive him, and Zeus let the pair split their time, one day on Olympus and one in the underworld, always together. Sailors prayed to them, and the electric glow sometimes seen on masts in storms, later called St Elmo's fire, was taken as a sign the twins were aboard.

The two heads of the constellation are bright stars of very different kinds. Pollux, the brighter, is an orange giant about 34 light years away, and in 2006 astronomers confirmed a giant planet orbiting it. Castor looks like one white star but is a family of six, three pairs bound together.

Gemini season runs through the end of the school year in much of the northern hemisphere and finishes at the June solstice. In the sky it is a quiet month for meteors, but long northern twilights make it a good time to watch the waxing Moon slide past the twins in the west after sunset.

Make it yours

A Gemini ritual: the two-column letter

Write to yourself as if you were your own twin.Photo: Matthew Henry / Burst

Try this today

  • One letter forward, one letter back. Keep both.
  • Seal them in an envelope and open it in Gemini season 2028.

The twins are a great excuse for a writing ritual. Take a page and write a short letter from the you of right now to the you of one year from now. Then turn the page and write the reply, as if the future you were writing back.

It sounds silly. It is surprisingly useful. The second letter usually knows what you actually want.

If you want a little sky timing, try it near the new moon in Gemini in early June, listed in the lunations table. Mercury, Gemini's ruler, is the planet of letters, so you are allowed to feel clever about it.

After dark

What to look at while Gemini hides

Castor and Pollux sink into the dusk in the west early in the season and then vanish behind the Sun. The midnight sky now belongs to Scorpius and Sagittarius. Southern viewers get the best of it: the scorpion's tail curls high overhead and the Milky Way's bright centre rises in the east. Northern viewers see Antares low in the south, with the Summer Triangle of Vega, Deneb and Altair climbing in the east.

Late autumn, not late spring

In the southern hemisphere Gemini season is early winter, heading toward the shortest day. The sign's social energy can show up as long dinners and big conversations indoors.

The Sun misses Gemini

By the IAU boundaries the Sun passes in front of Taurus (May 21 to Jun 21) this season. Gemini itself is never behind the Sun in these 31 days. Why signs and stars differ.

Quick answers

Is Mercury retrograde during Gemini season 2027?

Yes. Mercury stations retrograde partway through Gemini season 2027, as shown in the stations table above. It turns direct in the following season. See Mercury retrograde 2027 for every date including the shadow.

What is Gemini season good for?

Astrologers link Gemini, the mutable air sign ruled by Mercury, with talking, learning, writing, short trips, siblings and neighbours. Many people use the season to reconnect and pick up new interests.
