March Zodiac Sign: Pisces or Aries?

The March zodiac signs are Pisces, from March 1 to 20, and Aries, from March 21 to 31. It is also the month where the zodiac comes full circle, because Pisces is the twelfth and last sign and Aries is the first. The Sun passes from one to the other at the spring equinox, which in 2026 fell on March 20, a day before the date on most sign lists.

Aries and the equinox in 2026

Daylight saving time began on March 8, 2026, so the change came on Eastern Daylight Time. The Sun entered Aries on March 20 at 10:46 a.m. EDT, 14:46 UTC, the same minute as the published March equinox. That match is a useful check on the NovaOracles astronomy engine, which computes the Sun's position directly. Born on March 20, 2026, before 10:46 a.m. Eastern, you have a Pisces Sun; born later that day, an Aries Sun. The equinox is the reason Aries opens the zodiac. Astrologers in the Western tradition measure the signs from the point where the Sun crosses the celestial equator going north, and call that point zero degrees Aries. The twelve signs are equal thirty-degree slices of the Sun's yearly path, the ecliptic, counted from there. They are tied to the seasons, so they keep their dates even though the star patterns with the same names have slowly shifted over the centuries.

Pisces and Aries, an ending and a beginning

The two March signs sit side by side on the wheel, yet tradition treats them as opposite moods. Pisces is mutable water, ruled by Jupiter and in modern astrology by Neptune, and its reading is one of empathy and imagination, with loose edges between self and others. Aries is cardinal fire, ruled by Mars, and astrologers see in it the urge to start things and to act first. One gathers up the whole cycle, the other breaks new ground. North of the equator, Aries arrives with the first days of spring; in the Southern Hemisphere the same equinox opens autumn, and the sign dates stay exactly the same.

Pisces or Aries: checking a birthday near the equinox

From March 1 to 18 the answer is Pisces, and from March 22 to 31 it is Aries. Our own calculation for every year from 1930 to 2030 puts the Sun's move into Aries, in Eastern time, on the 19th, 20th or 21st, so a birthday on any of those days depends on the year and sometimes on the hour. The date and time of birth are the only things that decide it; a fiery or dreamy personality does not change where the Sun stood. To check a specific year, the zodiac sign dates tool gives the sign for any date and marks the days on which it switched.

The rest of your chart

Your March sign is the Sun, one piece of a much fuller picture. The Moon sign describes emotional needs and the rising sign the first impression you make, and together with the Sun they form the core trio many astrologers start from. An Aries with a Pisces rising, say, can come across as gentler than the Sun alone would suggest. The big three calculator works out all three from your date, time and place of birth.
