On 26 September 1981 the moon was 28 days in, near the close of the cycle, showing 3.0% of its face. That month's full moon — traditionally called the Corn Moon — had passed 12 days earlier, on 14 September 1981.

Moon in Virgo ♍

The moon was passing through Virgo on 26 September 1981, while the sun sat in Libra — which is why Serena Williams's star sign is Libra. The two rarely coincide: the sun takes a month to cross a sign and the moon takes about two and a half days.

Where the sun sign is read as the outward character, the moon sign is read as the emotional register underneath it — the part that copes by being useful and by putting something in order, and can turn worry into a task list.

Aspects that day

Aspects are the angles bodies form with each other. These were within orb on 26 September 1981:

What a New Moon birth moon means

In the absence of light, clarity arrives. This is the most powerful moment to decide what you are reaching toward. Set your intention and let it take root.

Traits of the New Moon

People born under a New Moon are often visionary, instinctive, and naturally drawn to beginnings. There is a freshness and spontaneity to their personality — they lead with intuition rather than waiting for all the facts. Serena Williams embodies this energy: a trailblazer who seems to operate on instinct and moves into new territory before others see it coming.

How to read all this

Every figure on this page is calculated from Serena Williams's date of birth — the phase, the illumination percentage, the positions and the aspects are astronomy, and they would be the same whoever was born that day. The character readings attached to them are symbolic tradition, not measurement, and are best treated as prompts for reflection rather than claims about a person.

Two things are deliberately missing. Without a birth time we cannot give a rising sign or house placements, since both change through the day — the ascendant shifts roughly every two hours. And without a birthplace there are no moonrise or moonset times, which depend on latitude. Anywhere you see those quoted for a public figure without a documented birth certificate time, treat them with caution.
