Astrology Calendar 2027: Sun Signs, Eclipses and Mercury Retrograde
By KosmoHow Kosmo makes its readings
This calendar gathers the main dates of the 2027 astrological year in one place: the twelve moments when the Sun moves into a new zodiac sign, the four seasonal turning points, the five eclipses and the three Mercury retrograde periods. All times are in UTC, calculated with NASA JPL Horizons and checked against the U.S. Naval Observatory and NASA’s eclipse predictions.
When the Sun changes sign in 2027
Sign change dates shift by about a day from year to year, which is why people born near a change sometimes find two answers for their sign. The exact moments for 2027 are below. Convert them to your time zone, since your local date can differ.

The four season markers match the U.S. Naval Observatory’s 2027 equinox and solstice times to the minute. The signs are tropical, as in most Western astrology, so the Sun enters Aries at the March equinox.

Eclipse dates are NASA’s, and the sign shown is the Moon’s position at greatest eclipse. The Mercury station dates match NASA JPL Horizons and the Mercury retrograde 2027 guide. For eclipse times, maps and safe viewing, see the eclipse calendar 2027 guide; for exact full and new Moon times, see the full Moon and new Moon calendars.
How to use an astrology calendar
Think of the calendar as a rhythm rather than a set of instructions. Many people mark the start of their own Sun sign season, check in at each equinox and solstice, and keep eclipse weeks a little lighter for reflection. Astrology is a symbolic tradition, so none of these dates decides events; they are prompts to pause and choose what matters to you.
Common questions
Why does my sign’s start date differ from other lists?
The exact moment the Sun enters a sign changes slightly each year and is often given in another time zone. Lists with fixed dates show typical ranges.
Are the eclipse times local?
No. Every time here is in UTC. The eclipse calendar 2027 guide explains how to convert them, and NASA’s maps show local circumstances.
Does Mercury retrograde mean I should avoid plans?
No. Mercury only appears to move backward from Earth. If you follow the tradition, use those weeks to double-check details, not to put your life on hold.
