Mark Zuckerberg's Birth Chart

The Moon ran from 10°00′ Scorpio to 24°14′ Scorpio across the local date. It had entered Scorpio roughly 16 hours 42 minutes before the date opened and still had 5°45′ to go at the close, so the sign is settled. Its contacts, except the Venus opposition, hang on the hour: conjunct Saturn until 5:50 PM, sextile Jupiter until 1:06 PM, conjunct Mars from 1:21 AM, opposite the Sun from 6:21 AM.

Any sign could be rising, though the turns were unequal here: Pisces and Aries each cleared the horizon in 1 hour 10 minutes, Leo and Scorpio in 2 hours 33 minutes. Sunrise at 5:37 AM and sunset at 8:05 PM leave the day-or-night question behind the sect calculator open, and no houses can be drawn.

Mars leads a ranking that sets prominence against frequency. Scorpio is a Mars sign in the traditional scheme, so the planet is strong by placement, yet it was crawling backward at 0°21′ a day; modern writers often call a retrograde Mars drive held in reserve.

Timing ranks third. Births within a week of an eclipse make up about one chart in 6, and this date ended 40 minutes before the peak of a penumbral lunar eclipse, a coincidence of the calendar.

Every planet from Mars outward was retrograde, six of the eight from Mercury to Pluto; five or more occur in about one chart in 6. Mercury, direct but slow, never left the final degree of Aries that day.

In the classical dignity table the Moon is in fall in Scorpio (about one chart in 12), and Jupiter at 12°38′ Capricorn shares that debility (about one chart in 10). Venus at 14°42′ Taurus holds its own sign (about one chart in 7), though at 8°49′ from the Sun older practice counts it under the beams. No planet was out of bounds; Jupiter went farthest south, to a declination of 22°41′.

Jupiter sextile Saturn barely moved, its orb held between 0°21′ and 0°23′, the lowest ceiling among the all-day aspects. Venus opposes the Moon, Mars and Saturn and trines Jupiter, tying a planet in its own sign to both planets in fall. Mercury opposite Pluto reached 0°20′, but across late Aries and early Scorpio, out of sign.

Earth and water hold four planets each, fire two, air none. Pluto, barely inside Scorpio, slipped back into Libra, an air sign, roughly 3.4 days after the date ended; on Pluto alone hang both the empty air column and the sixth fixed planet.

As cast, six of the ten planets sit in fixed signs, matched by about one chart in 30, the least common item listed here; modern astrologers tie fixed signs to persistence. The Moon, Mars, Saturn and Pluto crowd into Scorpio, and that wing, stretched to Jupiter, faces the Sun, Venus and Mercury, the layout Marc Edmund Jones named a seesaw.

Matched on what each chart settles, David Attenborough's page comes nearest, through the Taurus Sun. Lady Gaga follows on a shared Scorpio Moon, then Elizabeth II and Sachin Tendulkar, both Taurus Suns. Nobody on the roster shares the date.

Shifted back by the Lahiri ayanamsa of 23°38′, the settled picture loosens. The Sun crossed from Aries into Taurus roughly 2 hours 17 minutes after midnight, and the Moon reached Scorpio from Libra only 1 hour 2 minutes or so before the date ended. Jupiter moves into Sagittarius, one of its own signs, and Mars, Saturn and Pluto into Libra, an air sign.

Saturn's first return to its Scorpio degree fell on October 20, 2013, when Zuckerberg was 29.4 years old, and took a single crossing. Jupiter has returned three times so far: in 1996 and 2008 it needed three crossings each, turning retrograde over the spot, and in 2020 just one.

Positions were computed for the opening and closing midnight of the date on Eastern Daylight Time, UTC−4, in force in New York since April 29, 1984, and aspects sampled every 10 minutes of the local date.
