The record

What sets David apart

Ernest Walton (1903) and Riccardo Giacconi (1931) share the birthday in another year, so the sun sits where it sits here.

What the chart says

David, according to the stars

Core essence

David makes the room fairer just by being in it. The core of David is a feel for balance, in people, in colour, in who has not been asked their opinion yet. They are charming because they are genuinely interested, and they can see every side of a thing, which is a gift and, on a bad day, a very slow way to choose dinner.

The vibe

Underneath, David needs to be adored a little, and there is nothing wrong with that. The Moon in Leo feels things dramatically and generously and wants them noticed. What David needs to feel safe is to be chosen out loud: the compliment said in front of people, the text that says you were thinking of them. They repay it tenfold.

How David wants to be loved

David wants to be loved beautifully. Venus is at home in Libra: romance, manners, the date that was actually planned, a partner who is fair and easy to be around. David gives a lot of grace and needs it back. Treat them like a partner in everything, including the small choices, and they bloom.

How David creates

How David makes things happen: they grow upward. A Yang Wood day master is the tree, the one with a direction and the patience to keep at it through a bad season. David builds in the open, wants to be useful, and is at their most creative when there is something to reach for. Bend rather than break is the lesson they learn a few times.

Instinct

Instinct: David is bold, a Tiger year, and their gut reaction is to leap. Brave, generous, a bit dramatic, magnetic to be around, and never boring for a second. The Metal year sharpens it: principled, determined, clear about what is right.

Purpose

Purpose: Life Path 4 is the builder. David is here to make things that last, to put structure under other people's dreams, to be trusted with the real work. Loyal, practical, honest, and learning that the plan can bend without breaking.

Triggers

Triggers: being fenced in, and being lied to. Mars in Sagittarius fights loud, laughs it off, and is genuinely fine ten minutes later. David has boundless energy for anything with a horizon in it and none for the small print. Aim them at something far away and step back.

The sky over Glendale that night

Computed for 34.17°N, 9 p.m. local sky.

Overhead at Glendale at 9 p.m. that evening: Scheat of Pegasus, within 13.0° of the exact zenith.

Vega was the brightest thing up that night, one of 90 catalog stars above the horizon.

From 34.2°N not one of the brightest stars stays permanently above the horizon — all of them rise and set.

Nothing below −55.8° declination clears the horizon at this latitude, so Rigil Kentaurus, Achernar, Hadar, Acrux, Mimosa and Toliman were never visible from Glendale on any night.

The Moon was at waning crescent, 23% lit, and already below the horizon, with the Sun 43° down.

Where this comes from, and how it is worked out

David’s birth date and birthplace come from Wikidata Q315069 (CC0), as do the occupations, works and awards above. With no documented birth time this chart is rated X on the Rodden scale, the astrological convention for how well evidenced a birth time is. The banner above lists what that leaves out. Entries are matched to Wikidata by entity id rather than by name, kept at day precision, and dropped where sources disagree on the date.

Tropical zodiac, whole-sign houses, modern rulers. Aspects on the western_v1 orb policy; minor ones at 1.5° to 2.5°, skipped where a major already holds. Minor bodies from JPL Horizons heliocentric vectors, Lilith as mean apogee. Dominance is an AsterNym score — rulerships, dispositors, aspect count — so other methods can name a different leader.
