August 20 zodiac sign: Leo

Sun sign

Leo

Sun at noon UTC

26.6° to 28.0° 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 20, in every time zone on Earth, between 26.6° and 28.0° of the sign at noon UTC, so an August 20 birthday is a Leo birthday whatever the year or the hour.

At noon UTC on August 20 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 20 is its eighth day.

In most years August 20 is the 29th day of the Sun’s season in Leo, which runs from July 23 to August 22 counted at noon UTC, with two days of it still to come. August 20 is the 232nd day of a common year and the 233rd of a leap year, with 133 days of the year still to come after it.

August 20 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 20th is the 2 with a zero beside it, read in numerology as the partner’s number amplified: patience, tact and a gift for the long collaboration. In a fire sign the 2 is read as the loyal second, the friend whose courage shows most when someone they love is in trouble.

A question to carry from August 20: where would your warmth grow stronger if it asked for help instead of carrying everything alone?

The Sun in Leo and the number 2 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 2

Born on the 20th, 2 + 0 = 2, so your birthday number is 2: a 2 vibration supports sensitivity, partnership, diplomacy, and careful listening, with relational intelligence and patience as its gift and over-dependence, passivity, or people-pleasing as its strain.

Your 2027 numbers

For a birthday on August 20 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 20th reduces to 2, and 8 + 2 + 11 = 21, which reduces to 3, so 2027 is your Personal Year 3.

A Personal Year 3 is read as a year of expression, friendship and creative play, when what you make and say carries further than usual. Under the Universal Year 11 the reading adds inspiration, with the caution to finish what the bright ideas begin.

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

In 2027 August 20 falls on a Friday, the day the old reckoning gives to Venus, and is a Personal Day 4 (11 + 20 = 31, then 4) in a Personal Month 11 (3 + 8 = 11), while August is a master month 11; 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.
