August 13 zodiac sign: Leo

Sun sign: Leo
Sun at noon UTC: 19.9° to 21.3° Leo
Decan: Third of Leo, 20° to 30°
Element and mode: Fire, fixed
Ruling planet: The Sun

In every one of the 91 years from 1940 to 2030 the Sun stood in Leo for the whole of August 13, in every time zone on Earth, between 19.9° and 21.3° of the sign at noon UTC, so an August 13 birthday is a Leo birthday whatever the year or the hour.

At noon UTC on August 13 the Sun is in the third decan of Leo in 86 of those years and in the second in 5, so the decan, like the sign at a cusp, turns on the year. The third decan of Leo 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 August 13 to August 22, and August 13 is its first day.

In most years August 13 is the 22nd day of the Sun’s season in Leo, which runs from July 23 to August 22 counted at noon UTC, with nine days of it still to come. August 13 is the 225th day of a common year and the 226th of a leap year, with 140 days of the year still to come after it.

August 13 birthday personality

Both systems give the last face of Leo to Mars, and by triplicity it borrows the ram’s fire, so this is read as Leo with its sword drawn, brave, protective and quick to take up a cause. The lesson the tradition attaches is the difference between courage and the need to be seen being brave.

The 13th reduces to 4, and modern numerology counts 13 among its karmic debt numbers: a symbolic lesson about steady, honest work, which the Almanac reads as a pattern of growth and never as punishment or bad luck. The 4 underneath it is the builder’s number. With fire, the 4 is read as willpower given a routine, ambition that gets up early and does the unglamorous part.

A question to carry from August 13: which small daily habit would give your warmth the ground it needs?

The Sun in Leo and the number 4 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 4, through 13

Born on the 13th, 1 + 3 = 4, so your birthday number is 4: a 4 vibration supports structure, discipline, foundations, work, and stability, with structure and reliability as its gift and rigidity, fear, or over-control as its strain. The day itself, 13, is one of the four karmic debt numbers, 13, 14, 16 and 19, a flag raised only for a number’s own total, and the Almanac reads it as a lesson to grow through, never as a punishment or a curse.

For a birthday on August 13 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: August, the 8th month, gives 8, the 13th reduces to 4, and 8 + 4 + 11 = 23, which reduces to 5, so 2027 is your Personal Year 5.

Numerology reads a Personal Year 5 as a lively year of change, movement and new experience. Under the Universal Year 11 the reading favours the changes that follow an honest sense of direction.

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

In 2027 August 13 falls on a Friday, the day the old reckoning gives to Venus, and is a Personal Day 8 (4 + 13 = 17, then 8) in a Personal Month 4 (5 + 8 = 13, then 4), while June is a master month 11; the Personal Year itself turns on 1 January, not on the birthday.

August birthstone and birth flower

Birthstones: Peridot, spinel and sardonyx
Birth flowers: Gladiolus, and poppy as the second flower

August’s peridot, spinel and sardonyx come from the modern list (the Jewelers of America list of 1912, as since revised), and its gladiolus and poppy from The Old Farmer’s Almanac.
