Note: All moon phase dates and times are in UTC (Coordinated Universal Time). Calculated using the Meeus simplified synodic month algorithm (epoch J2000.0). Depending on your time zone, the phase may fall on a different calendar date. For example, a Full Moon at 01:30 UTC on January 14 will be January 13 in US Eastern time (EST, UTC−5).
Frequently asked questions
- How often does a Full Moon occur?
- A Full Moon occurs roughly every 29.5 days (one synodic month). Most months have one Full Moon, but occasionally a month will have two — the second is called a Blue Moon.
- What is a Blue Moon?
- A Blue Moon is the second Full Moon in a single calendar month. This happens about every 2–3 years. The next Blue Moon after 2021 can be found by checking our Full Moon calendar.
- Why are moon phase times in UTC?
- Astronomical calculations use UTC as the standard reference time. This avoids confusion from time zones and daylight saving time. Convert to your local time by adding or subtracting your UTC offset.
