Planet Sign Changes 2027

The year in sign changes

In plain Englisha sign change (astrologers say ingress) is the moment a planet moves from one sign into the next. The Sun does it once a month, and slower planets do it rarely.

Sun (the seasons)

The Sun’s ingresses set the astrological seasons. It enters Aries at the March equinox (Mar 20), Cancer at the June solstice, Libra at the September equinox and Capricorn at the December solstice.

Mercury

Mercury changes sign undefined times because its retrograde periods send it back across a boundary. Rows marked “moving backward” are retrograde re-entries, and each one is followed by a forward crossing again later.

Venus

Venus spends about four weeks in each sign and has no retrograde period in 2027, so every crossing is forward.

Mars

Mars stays about six weeks in a sign. It moves backward across the Virgo and Leo border in February during its retrograde and crosses forward again in May.

Jupiter

Jupiter normally spends about a year in each sign. It changes sign once in 2027, leaving Leo for Virgo.

Planets that do not change sign

In plain Englishthe slowest planets stay in one sign all year.

Saturn, Uranus, Neptune and Pluto are slow enough that a sign change comes only every few years, so for 2027 their sign is fixed. They still go retrograde and direct inside their signs: see the 2027 retrogrades page for the dates.

Why Mercury and Venus change sign so often

In plain Englishthe closer a planet is to the Sun, the faster it seems to move across the zodiac.

Mercury and Venus orbit inside Earth’s orbit, so they stay near the Sun and cross signs quickly. Mars takes about two years to go around the zodiac, Jupiter twelve, and Saturn about twenty-nine. That is why Saturn, Uranus, Neptune and Pluto have no row in 2027.

How to use this table

In plain Englishwhen a planet changes sign, the topic that planet rules takes on a different tone.

Mercury is how you talk and think, so Mercury in a new sign shifts the style of the conversation. Venus is taste and affection, and Mars is drive. You can follow your own chart by looking for the planets in your sign and houses on the birth chart calculator. All of these times are computed from planetary positions, to the minute, and rounded the same way as on the other 2027 pages. The current positions are on today’s sky, and the Mercury dates in particular are on the Mercury retrograde page.
