Usain Bolt's Birth Chart

Pisces contained the Moon for the whole date: it stood at 16°16′ Pisces when the day opened and at 29°45′ Pisces when it closed, so every hour gives a Pisces Moon. The margin is thin: the Moon reached Aries less than half an hour after the date ended. Both midnights fall in the Full Moon phase, which the moon phase calculator explains.

Pisces and Aries, the quickest signs, each rose in 1 hour 35 minutes; Cancer and Sagittarius, the slowest, took 2 hours 13 minutes. Leo's turn on the Ascendant opened at 3:53 AM and closed at 6:05 AM, taking in sunrise at 5:53 AM. Astrotheme's unsourced 2:00 PM falls in the Sagittarius span. No houses are drawn without the hour.

Ranking weighs how much astrologers make of a feature against how often 1980s charts carry it. Mars fills three of the ranked entries; with the Sun, Venus and Jupiter each in a sign they rule, four of the seven classical planets sit in rulership or exaltation.

Mars crept just 0°07′ over the whole date and ended it at 12°05′ Capricorn, a nearness to its station matched by about one chart in 13 from the decade. Traditional astrology exalts Mars in Capricorn, a placement shared by about one chart in 10, and its declination, 28°09′ south at noon, lay beyond the Sun's limit of 23°26′ all day (about one chart in 6). Declination specialists read that as Mars working outside convention.

When the day began the Sun was at 27°51′ Leo, inside its own sign. Venus, at 13°47′ Libra, and retrograde Jupiter, at 20°27′ Pisces, were likewise at home. Counting either of each planet's two signs, Venus at home turns up in about one chart in 7 from the 1980s and Jupiter at home in about one chart in 5; Jupiter retrograde in any sign, in about 31%. Mercury sat 14°51′ behind the Sun, under the beams.

All day, eight aspects held. The closest, Mercury sextile Venus, was 0°24′ wide at noon. Venus in its own sign squared Mars in its exaltation (2°15′), and Jupiter squared Uranus (2°02′). The Sun's square to Saturn and trine to Neptune both cross sign lines, which some traditional astrologers refuse to count. Another nine depend on the hour, the longest-lasting being the Moon conjunct Jupiter, in orb from midnight until 10:12 PM.

The Moon and Jupiter in Pisces face everything else, a chain whose ends are Mercury (Leo) and Mars (Capricorn); the widest empty arc, 140°48′ at noon, parts the Moon from Mercury. Marc Edmund Jones would class this as a seesaw, a layout about 30% of 1980s charts take. Fire holds four planets; Venus is alone in air.

No databank page shares both of Bolt's settled signs. Whitney Houston and Barack Obama share his Leo Sun, Marie Curie and Robin Williams his Pisces Moon; Houston ranks first, her Sun through Saturn, the Moon aside, lying on average about 50 degrees from his. The roster holds no other birth on August 21, 1986.

In Lahiri's sidereal zodiac, which lagged the tropical by 23°40′ that year, the Sun stays in Leo, at 4°11′ as the day opened, but Mercury falls back into Cancer, Venus into Virgo, its debilitation, Mars into Sagittarius and Jupiter into Aquarius. The sidereal Moon moved from Aquarius into Pisces early in the afternoon, so a Vedic Moon sign for Bolt needs the hour.

Saturn needed three passes to complete its first return, the opening one on January 28, 2015 and the last on October 24, 2015. Jupiter has returned three times, most recently on March 28, 2022. Jupiter shifted only 0°06′ on August 21 itself and Saturn less, so the unknown hour barely moves these dates.

Positions come from precise astronomical calculations for Sherwood Content at both local midnights and at noon, checked against the site's chart service (largest difference < 0.0002°). The Moon covered 13°28′ between them, so aspects were tested every 10 minutes of the local date; rates count how often each feature appears among random 1980s births in a Monte Carlo sample.
