Last Quarter

37.2% illuminated

Singer, songwriter

On 8 October 1985 the moon was 23 days in, at about the three-quarter point, showing 37.2% of its face. That month's full moon — traditionally called the Corn Moon — had passed 9 days earlier, on 29 September 1985.

Moon in Leo ♌

The moon was passing through Leo on 8 October 1985, while the sun sat in Libra — which is why Bruno Mars'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 needs warmth and recognition, and is generous with both once it feels secure.

Aspects that day

Aspects are the angles bodies form with each other. These were within orb on 8 October 1985:

What a Last Quarter birth moon means

The cycle moves toward completion. What needs to end before something new can begin? Name it, honour it, and release it with grace.

Traits of the Last Quarter

Last Quarter births are philosophical, transformative, and drawn to endings and beginnings. They understand instinctively that letting go is the path forward. Bruno Mars has shown this quality repeatedly — the ability to release what is no longer working and reinvent without losing their core.

How to read all this

Every figure on this page is calculated from Bruno Mars'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.
