The 2027 Astrology Calendar: Every Date, Computed

Every time and degree on this page was calculated from an ephemeris on November 13, 2026, not taken from another website. All times are US Eastern. That matters more than it should have to: a good deal of what is published about these dates does not match any ephemeris, and the errors get copied from site to site until they look like consensus.

The shape of 2027

2027 is a settling year. The great reshuffle happened in 2026, when Neptune, Saturn and Uranus all changed sign within a few months of each other. None of them moves again this year. What that leaves is a year you live inside those placements rather than bracing for them, with two genuine disruptions: the Mars retrograde that opens January, and the eclipses.

Every retrograde in 2027

Nine in all. The dates are the stations, the moments apparent motion changes direction, and the degrees are where each one turns.

Mercury retrograde in 2027

Three, which is the usual number. All three begin in one sign and reverse into the one before it, so each tends to start as one subject and end as another.

Three weeks each, roughly nine weeks of the year in total. It is worth knowing that the shadow periods either side, when Mercury covers the same degrees forwards, run about two weeks longer at each end, which is why the effect often seems to start before the date and finish after it.

Eclipses in 2027

Five, in two seasons. Eclipse degrees matter because an eclipse falling within a degree or two of something in your own chart is the one you feel.

Ingresses: what changes sign

One. That is unusual enough to be the defining fact of the year.

Jupiter leaves Leo and enters Virgo on July 26, 2027, 12:45 AM ET, where it stays until mid 2028. Saturn, Uranus, Neptune and Pluto all hold their signs from January to December. If you read that 2027 is the year Saturn enters Aries or Uranus enters Gemini, that page is a year behind: both happened in 2026.

New and full moons

Twenty-five lunations across the year. The full moons are listed with the degree, because a full moon within a couple of degrees of a planet in your chart is the one that keeps you up.

Your year, by rising sign

These dates are the same for everybody. Where they land in your life is not, and that depends on your rising sign rather than your Sun. Each of these reads the year above against one of the twelve: Aries, Taurus, Gemini, Cancer, Leo, Virgo, Libra, Scorpio, Sagittarius, Capricorn, Aquarius, Pisces.
