How to read this calendar
A factual clock with an optional symbolic layer.
Calculated: Moon longitude, zodiac sector, illumination, exact phase crossing, and apparent planetary direction. Interpretive: any meaning attached to a phase or planet. Astrology can structure reflection; it does not prove or guarantee an event.
Times are shown in UTC so archived month pages remain stable and checkable. Open a date for all planetary positions, or use today’s Moon phase for the live cycle and next ingress.

Clear answers
Frequently asked questions
When is the New Moon in September 2025?
The New Moon occurs in Virgo on September 21, 2025 at approximately 19:53 UTC. It is the instant geocentric Sun–Moon elongation crosses zero degrees.
When is the Full Moon in September 2025?
The Full Moon occurs in Pisces on September 7, 2025 at approximately 18:08 UTC. It is the instant geocentric Sun–Moon elongation crosses 180 degrees.
Which Moon sign is shown for each day?
Each calendar square shows the Moon’s tropical zodiac sign at 12:00 UTC on that date. The Moon moves into a new sign every two to three days, so a sign change can occur earlier or later in your local day. Open a date to see its noon position and the next calculated ingress time.
Why can a Moon phase appear on a different date in another time zone?
A principal phase happens at one instant worldwide, but the local calendar date at that instant depends on time zone. MyMysticDay prints the exact result in UTC so every page uses one unambiguous reference. Convert the listed time to your local zone when planning for your location.
Does this lunar calendar include retrograde stations?
1 calculated planetary direction-change marker fall inside September 2025. They appear on the exact calendar dates and link to the complete retrograde tracker. A station is apparent motion viewed from Earth, not a planet physically reversing.
Is this Moon calendar astronomical or astrological?
The dates, longitude, illumination, sign boundaries, and phase crossings are calculated astronomical positions expressed in the tropical zodiac. The planning language attached to them is astrological tradition. The page keeps those two layers separate so a measured fact is not confused with an interpretation.
