March 20 zodiac sign

When the Sun enters Aries, year by year

The exact moment for every year from 1940 to 2035, and what that made March 20. Switch the time zone to match where you were born.

March 20 in the sky

In most years, March 20 is the date of the March equinox in US time zones. At that instant the Sun crosses the sky's equator heading north, and spring begins in the Northern Hemisphere, with day and night close to equal length across the globe. The tropical zodiac, which most Western astrologers work with, defines the start of Aries as that exact moment. The hours before it are the last of Pisces, the twelfth sign, which closes the zodiac's loop, and the hours after it start the loop over. Pisces is mutable water, a sign that adapts to its surroundings and soaks them up. Aries is cardinal fire, which starts things and expects others to keep up.

Pisces at the very end of the zodiac

In Eastern time a bit more than half of March 20 births are Pisces, and Pisces gets more likely the further back the birth year goes. A Pisces born on this date has the Sun in the sign's closing degree. Astrologers in some schools name it the anaretic degree and link it to urgency, a pull to finish what the sign began. For Pisces that often looks like empathy with a deadline. You may be the friend who stays after the party to wash glasses and hear the whole story of someone's breakup, and you often sense how a situation should end before anyone says it.

Jupiter rules Pisces, with Neptune as its modern co-ruler, so your kindness can be generous to the point of blurry. You might say yes to three plans for the same night, then feel awful canceling two of them. A one-plan-per-evening rule takes some of that guilt away. Your imagination is a strength here. You tend to picture the end of a trip or a hard conversation in detail, and that picture often guides you better than a list would.

When March 20 makes you an Aries

You are an Aries if you arrived after that year's equinox moment, which has grown more common over time. In the mid-1900s the equinox often came late on March 20 or slipped to March 21, leaving most of the day to Pisces. This century it tends to arrive earlier, and lately some leap years have had it on March 19 in US time, making all of March 20 Aries. Pacific clocks also run three hours behind Eastern ones, so more of the day is Aries in Los Angeles than in New York. An Aries born this close to the line is brand new to the sign, and often shows it by starting things before anyone agrees on a plan.

Pisces or Aries: what changes

Going from Pisces to Aries swaps water for fire. Water signs work through feeling and take in the mood around them, while fire signs act first and sort out the feelings later. The mode flips too, from mutable, which adjusts to whatever is happening, to cardinal, which decides what happens next. The ruler changes from Jupiter and Neptune, which govern belief and daydreams, to Mars, the planet of drive and temper. In daily life the clearest test is a stalled group plan. A Pisces tends to check how everyone feels and smooth things over without much fuss. An Aries picks a restaurant and books it before the group chat has finished arguing.

Why a March 20 birthday can feel like both signs

People call March 20 a cusp birthday as if it meant a blended Pisces-Aries sign, but the Sun only ever occupies one sign, and your birth moment puts it on one side of the line. You can still feel like both for concrete reasons. Mercury always travels close to the Sun, and most people born on March 20 have it in Pisces, so even an Aries born that day often talks in a softer, roundabout way. Venus could be anywhere from Aquarius to Taurus. Your Moon sign (your emotional style) and rising sign (the first impression you give) also count, and a birth chart lists both.
