August 31 Birthday: Virgo, Birthday Number 4 & Personal Year 2027
Some birthday facts never change: August 31 is always a Virgo date with birthday number 4. Others move each year, like the Personal Year — 4 in 2026, 5 in 2027. This page lays out both kinds, with a planning table for 2027.
August 31 sun sign: Virgo
Counting from the first day of Virgo on August 23, August 31 is day 9 of 31 — early in the season. Astrology writers often describe these first days as the sign in its most direct form. Virgo, pictured as a maiden holding a sheaf of grain, is traditionally ruled by Mercury; its season is harvest time, with imagery of sorting, refining and getting things right.
In the usual descriptions, Virgo is precise, helpful and analytical. Applied to work, the tradition puts it like this: “You may enjoy improving systems and getting details exactly right.” Whether it fits is for you to judge; the tradition only provides the vocabulary.
Earth signs are traditionally described as practical and grounded — results you can touch matter. Virgo shares the earth element with Taurus and Capricorn, a trio often described as patient, practical and good with real-world details. Virgo is a mutable sign: its season closes a quarter of the year and hands over to the next, so the tradition links mutable signs with adaptability and transitions.
Born in August
Gift guides and jewelers pair August with peridot, spinel or sardonyx; florists pair it with gladiolus and poppy. August honors Augustus and is one of only three months with three birthstones on the modern list.
Birthday number 4: the 31st
3131 → 4Birthday number 4 is usually summarized as order and diligence — the satisfaction of doing a job properly. Because 31 adds up to 4, numerologists group the 31st with the other days that reach 4, and some also read the separate digits 3 and 1.

Chinese zodiac and August 31
