April 1 zodiac sign: Aries

Sun sign: Aries
Sun at noon UTC: 10.9° to 12.3° Aries
Decan: Second of Aries, 10° to 20°
Element and mode: Fire, cardinal
Ruling planet: Mars

In every one of the 91 years from 1940 to 2030 the Sun stood in Aries for the whole of April 1, in every time zone on Earth, between 10.9° and 12.3° of the sign at noon UTC, so an April 1 birthday is an Aries birthday whatever the year or the hour.

At noon UTC on April 1 the Sun is in the second decan of Aries, 10° to 20°, in every one of those years, a face that belongs to the Sun in the Chaldean order and is read through Leo, ruled by the Sun, by triplicity, so the two systems agree; in most years the decan runs from March 31 to April 9, and April 1 is its second day.

In most years April 1 is the 12th day of the Sun’s season in Aries, which runs from March 21 to April 19 counted at noon UTC, with 18 days of it still to come. April 1 is the 91st day of a common year and the 92nd of a leap year, with 274 days of the year still to come after it.

April 1 birthday personality

Both systems give the middle of Aries to the Sun, and by triplicity it borrows Leo’s warmth, so the ram’s impulse is read as wanting to lead from the front and be seen doing it. The tradition calls it a generous fire, quick to champion others, and asks only that pride not become the fuel.

Born on the 1st, you carry the number in its plainest form, with no compound behind it, only the 1 of beginnings. Numerologists read the first of the month as the self-starter, someone who would rather go first than wait to be asked. In a fire sign the 1 doubles the urge to begin, so the tradition reads a born initiator who is happiest with a fresh start in hand.

A question to carry from April 1: where could your courage make the first move you have been waiting for someone else to make?

The Sun in Aries and the number 1 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 1

Born on the 1st, your birthday number is simply 1, the day itself: a 1 vibration supports initiative, courage, leadership, and clear beginnings, with initiative and self-direction as its gift and impatience, isolation, or ego pressure as its strain.

For a birthday on April 1 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: April, the 4th month, gives 4, the 1st gives 1, and 4 + 1 + 11 = 16, which reduces to 7, so 2027 is your Personal Year 7. On the way it passes 16, a karmic debt number, read in a year as a lesson to work through rather than as bad luck.

A Personal Year 7 is read as a year of reflection, study and rest, when the inner life asks for more room than the calendar. With 2027 a Universal Year 11 the tradition reads it as a year of real insight for anyone who makes time to be quiet.

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

In 2027 April 1 falls on a Thursday, the day the old reckoning gives to Jupiter, and is a Personal Day 3 (11 + 1 = 12, then 3) in a Personal Month 11 (7 + 4 = 11), while April is a master month 11; the Personal Year itself turns on 1 January, not on the birthday.

April’s diamond comes from the modern list (the Jewelers of America list of 1912, as since revised), and its daisy and sweet pea from The Old Farmer’s Almanac.
