The Moon in August 2025
In August 2025 the Moon changes zodiac sign 13 times and passes through all 12 signs. It starts the month in Scorpio on August 1 and ends it in Sagittarius on August 31. Counting the sign it occupies at noon UTC each day, it spends the most days in Scorpio (5 days), Sagittarius (4 days) and Aries (3 days).
The main lunar phases this month are: First Quarter on August 1 in Scorpio, Full Moon on August 9 in Aquarius, Last Quarter on August 16 in Taurus, New Moon on August 23 in Virgo and First Quarter on August 31 in Sagittarius.
For context: the Moon circles the zodiac in about 27.3 days, so it usually stays in one sign for roughly 2 to 2.5 days before moving on. Its phases follow the longer synodic month of about 29.5 days — the time from one new moon to the next — which is why each phase lands on a different date every month. All times here are UTC, so a sign change or phase near midnight may fall on the neighboring date in your time zone.
