Every date that shapes the 2027 sky, in one place: Mercury retrograde, the eclipses, the full moons by name, the solstices and the zodiac seasons.

Mercury retrograde 2027

Each Mercury retrograde lasts about three weeks. In 2027 the first runs back from Pisces into Aquarius, the second from Cancer into Gemini, and the third from Scorpio into Libra — so each one covers the first degrees of one sign and backs into the last degrees of the sign before it. Full details, plus every other planet's stations, are on the retrograde calendar 2027.

Every retrograde active in 2027

Uranus, Neptune and Pluto turn retrograde every year for around five months, so for most of the year at least one planet is retrograde. That is normal, not ominous. What matters for you is whether a station lands near a planet in your own chart.

Eclipses 2027

The eclipses of 2027 fall on the Leo–Aquarius axis, with the lunar eclipses drifting into Virgo and Capricorn. Times are the moment of maximum eclipse worldwide, not local visibility. See the eclipse calendar 2027.

Full moons 2027, by name

The names are the North American set popularised by the Old Farmer's Almanac. The Harvest Moon is the full moon closest to the September equinox. Origins, distances and supermoon details are on full moon names 2027. For the sign meaning of each lunation, see the moon calendar 2027.

Solstices and equinoxes 2027

Each solstice and equinox also starts a zodiac season: Aries at the March equinox, Cancer at the June solstice, Libra at the September equinox and Capricorn at the December solstice. Every US time zone is on solstice & equinox 2027.

Zodiac seasons 2027

These are the exact moments the Sun enters each sign, which shift by up to a day from year to year. If you were born near a cusp, the zodiac seasons 2027 page and your free natal chart will settle which sign is yours.

Making 2027 personal

A date list tells you when the sky changes; it can't tell you which changes you'll feel. That depends on where these degrees fall in your birth chart. A Mercury station at 6° Pisces passes almost unnoticed unless you have a planet near 6° Pisces. Cast your free natal chart, note your planets' degrees, and compare them with the tables above. The dates closest to your own placements are the ones to watch in 2027.
