William, Prince of Wales's Birth Chart

The yod and the two stations, four of the eight ranked features, hold at any hour of June 21. By contrast, the Sun on the horizon (the least common of the eight), the Sun on the Descendant and Jupiter at the Midheaven rest on the Gazette's evening minute.

The base pairs Neptune in Sagittarius with Pluto in Libra, a sextile 1°22′ from exact. Venus, at 25°39′ Taurus, is a quincunx from both: 0°07′ from Neptune, the chart's closest contact, and 1°30′ from Pluto. Writers on the yod describe its apex as a point pressed to keep adjusting; this apex is Venus in its own sign and top of the strength table. Neptune, 1°56′ from the Ascendant, ties the rising degree in as well.

The minute was read off the scanned Gazette page, issue 49027, page 8215. An unattributed web page, now offline, was reported to give 9:03 AM; the notice's word “evening” rules it out, and that hour would put Leo on the Ascendant, move every planet to a new house and leave both lights in Gemini.

Sun and Moon each switched sign on June 21: the Moon into Cancer at 1:12 PM, the Sun at 6:22 PM, the solstice, 2 hours 40 minutes before the birth, a same-day solar ingress seen in about one chart in 31. Houses are touchier than the rising sign: Venus enters the 4th house if the birth is moved 7 minutes later, Jupiter the 10th house if moved 8 minutes earlier.

Saturn, exalted at 15°30′ Libra, was creeping forward by about 21 arc-seconds a day after its station. Jupiter, retrograde, would stand still within six days; Jupiter near a station appears in about one chart in 11, and tradition treats a stationary planet as emphatic. As chart ruler it also sits 1°58′ short of the Midheaven (about one chart in 15), while the Sun lies 2°37′ past the Descendant in the 7th house (about one chart in 9).

The tightest major aspects are trines, Mercury to Mars at 0°14′ and the Sun to Jupiter at 0°22′, and both pairs share an element: Mercury and Mars sit in air signs, the Sun and Jupiter in water signs. Classical authors count such trines among the easy contacts. The Moon also applies to a square with Mars, 4°14′ wide.

The planets from Venus to the Moon face those from Mars to Neptune across two wide gaps, a seesaw. Water and air tie, the Sun's sign tipping it to water; of the ten planets, Venus alone is in an earth sign. At London's latitude the Placidus cusps skip four signs, Cancer among them, so both lights sit in an intercepted sign.

Sitting 1°24′ over the western horizon, 18 minutes before sunset, the Sun still makes this a day chart, by a whisker; a Sun that close to the horizon appears in about one chart in 32. Hellenistic writers group Jupiter and Saturn with the Sun as day planets, so all three are in sect here, while Mars, out of sect and in detriment, scores lowest.

The Moon, at 4°57′ Cancer, is 4°51′ from the Sun and combust, as in about one chart in 24; a partial solar eclipse had fallen 7 hours 59 minutes earlier. The Sun's declination, 23°26′, sat at the year's maximum, yet no planet was out of bounds.

Harrison Ford, nearest in the databank, alone among the four closest charts has both lights in Cancer. Priyanka Chopra matches the Sun and, within a degree each, William's Jupiter and Saturn; MS Dhoni and Ariana Grande share the Cancer Sun alone. The databank holds no other birth on June 21, 1982.

Subtract the Lahiri ayanamsa of 23°36′ and both lights drop back into Gemini; Mars and Saturn land in Virgo, Jupiter slips into Libra, and Mercury joins Venus in Taurus, while the Ascendant holds Sagittarius at 3°52′.

Saturn first reached its birth degree again on December 12, 2010, recrossed it while retrograde on March 13, 2011 and made its last pass on September 4, 2011. Jupiter returned on November 12, 1993, October 28, 2005 and October 12, 2017.

The hospital's coordinates, 51°31′ N, 0°10′ W, feed precise astronomical calculations, read tropically with Placidus houses and checked against the site's chart API (difference < 0.0002°). A rate on this page is the fraction of simulated 1980s births, scattered over world cities and cast by the same code, in which the feature appears.
