The Moon in September 2030
In September 2030 the Moon changes zodiac sign 13 times and passes through all 12 signs. It starts the month in Libra on September 1 and ends it in Scorpio on September 30. Counting the sign it occupies at noon UTC each day, it spends the most days in Scorpio (4 days), Libra (3 days) and Pisces (3 days).
The main lunar phases this month are: First Quarter on September 4 in Sagittarius, Full Moon on September 11 in Pisces, Last Quarter on September 19 in Gemini and New Moon on September 27 in Libra.
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.
