What an August 31 birthday means
On August 31 the Sun sits between 6.7° Virgo and 9.0° Virgo in every year from 1950 to 2025, counting every hour of the day in UTC. Its usual noon position is 7.9° Virgo.
That places August 31 in the first decan of Virgo. The modern triplicity system gives this decan to Virgo, the older Chaldean order gives it to the Sun, and the Golden Dawn tradition pairs it with the Eight of Pentacles.
Virgo is an earth sign of the mutable modality, ruled by Mercury. Earth signs trust what they can touch, count and build on. Mutable signs adapt: each one closes a season and gets ready for the next.
August 31 is about 7 days from the nearest sign change, so the Sun is in Virgo on this date in every year charted.
Where these figures come from
The Sun's position was charted at 12:00 UTC on every day from 1950 to 2025, and the start and end of each date were placed on the straight line between neighbouring days, which is exact to a small fraction of a degree. The range covers every hour of August 31 in UTC across all 76 years; someone born far from UTC can sit up to about half a degree beyond it. Decans follow two traditional systems: the triplicity system, which gives each third of a sign to the three signs of its element in turn, and the older Chaldean order of faces, which runs through the seven classical planets from Mars at the start of Aries.
