August 21 zodiac sign: Leo

Sun sign

Leo

Sun at noon UTC

27.6° to 29.0° 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 21, in every time zone on Earth, between 27.6° and 29.0° of the sign at noon UTC, so an August 21 birthday is a Leo birthday whatever the year or the hour.

At noon UTC on August 21 the Sun is in the third decan of Leo, 20° to 30°, in every one of those years, 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; in most years the decan runs from August 13 to August 22, and August 21 is its ninth day.

In most years August 21 is the 30th day of the Sun’s season in Leo, which runs from July 23 to August 22 counted at noon UTC, with one day of it still to come. August 21 is the 233rd day of a common year and the 234th of a leap year, with 132 days of the year still to come after it.

August 21 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.

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.

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

The Sun in Leo 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.

Your 2027 numbers

For a birthday on August 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: August, the 8th month, gives 8, the 21st reduces to 3, and 8 + 3 + 11 = 22, a master number the Almanac keeps whole, so 2027 is your Personal Year 22.

A Personal Year 22 is a master year, the master builder’s, kept whole rather than reduced to 4, read as a year to give a large vision a practical form. In a Universal Year 11 the tradition reads the inspiration as already there, and the work as building it to last.

Personal Months of 2027, a Personal Year 22: Jan 5 Feb 6 Mar 7 Apr 8 May 9 Jun 1 Jul 11 Aug 3 Sep 4 Oct 5 Nov 33 Dec 7

In 2027 August 21 falls on a Saturday, the day the old reckoning gives to Saturn, and is a Personal Day 6 (3 + 21 = 24, then 6) in a Personal Month 3 (22 + 8 = 30, then 3), while July is a master month 11 and November is a master month 33; the Personal Year itself turns on 1 January, not on the birthday.

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.
