March 21 zodiac sign: Pisces or Aries

Sun sign: Pisces or Aries, a cusp day
Sun at noon UTC: 0.0° to 1.4° Aries, or 30.0° to 30.0° Pisces
Decan: First of Aries, 0° to 10°
Element and mode: Fire, cardinal
Ruling planet: Mars

March 21 is a cusp birthday, usually Aries; in some years the Sun is still in Pisces for part of this date, so check your birth year and time: in 27 of the 91 years from 1940 to 2030 the Sun crossed from Pisces into Aries during March 21 counted in UTC, most recently in 2007, and at noon UTC it stood in Aries in 90 of the years and in Pisces in 1. For a birth on March 21 the year, the time and the place settle the sign: convert the time of birth to UTC and compare it with the minute the Sun changed sign that year, or let the zodiac sign calculator do it from your date, time and city.

At noon UTC on March 21 the Sun is in the first decan of Aries in 90 of those years and in the third decan of Pisces in 1, so the decan, like the sign at a cusp, turns on the year. The first decan of Aries is a face that belongs to Mars in the Chaldean order and is read through Aries, ruled by Mars, by triplicity, so the two systems agree, and in most years the decan runs from March 21 to March 30, and March 21 is its first day.

In most years March 21 is the 1st day of the Sun’s season in Aries, which runs from March 21 to April 19 counted at noon UTC, with 29 days of it still to come. March 21 is the 80th day of a common year and the 81st of a leap year, with 285 days of the year still to come after it.

March 21 birthday personality

This is Aries at its least diluted: both systems hand the first ten degrees back to Mars, the sign’s own ruler, so the tradition reads a birthday here as the spark before the plan. Its gift is nerve and a clean start, and the lesson the old texts attach to it is patience with people who move at an ordinary pace.

Born on the 21st, 2 and 1 add to 3: partnership and initiative turning into expression. Numerology reads it as a sociable, creative birthday, the host who is also the entertainer. The tradition reads fire with a 3 as a born encourager, quick with praise and quicker with a plan for the evening.

Where Pisces gives way to Aries the zodiac’s year turns over, the dreamer handing on to the pioneer at the March equinox. Some readers take a birthday this close to the change to carry something of both signs, a symbolic reading the calculation cannot measure; which sign the Sun was in at a birth is a matter of fact, settled by the year, the time and the place.

A question to carry from March 21: what would your courage make if it set aside the fear of how it will be received?

The Sun in Aries and the number 3 are only part of the story: your Moon, your rising sign and the rest of your chart have as much to say, and the tradition offers all this as a mirror, never a verdict.

Birthday number 3

Born on the 21st, 2 + 1 = 3, so your birthday number is 3: a 3 vibration supports creativity, communication, joy, and expressive movement, with creative communication as its gift and scattered focus, avoidance, or emotional dramatization as its strain.

For a birthday on March 21 the house method reduces the birth month and the day on their own and adds the Universal Year of 2027, 11 (2 + 0 + 2 + 7 = 11, a master number kept whole), as it stands: March, the 3rd month, gives 3, the 21st reduces to 3, and 3 + 3 + 11 = 17, which reduces to 8, so 2027 is your Personal Year 8.

A Personal Year 8 is read as a year of achievement and authority, when effort can turn into reward and recognition. In a Universal Year 11 the tradition asks that power and money be used with integrity and vision.

Personal Months of 2027, a Personal Year 8: Jan 9 Feb 1 Mar 11 Apr 3 May 4 Jun 5 Jul 6 Aug 7 Sep 8 Oct 9 Nov 1 Dec 2

In 2027 March 21 falls on a Sunday, the day the old reckoning gives to the Sun, and is a Personal Day 5 (11 + 21 = 32, then 5) in a Personal Month 11 (8 + 3 = 11), while March is a master month 11; the Personal Year itself turns on 1 January, not on the birthday.

Birthstones: Aquamarine and bloodstone
Birth flowers: Daffodil, and jonquil as the second flower

March’s aquamarine and bloodstone come from the modern list (the Jewelers of America list of 1912, as since revised), and its daffodil and jonquil from The Old Farmer’s Almanac.
