Moon Phase Calculator
Any date, past or future.
No place needed: the phase is the same everywhere on Earth.

About this tool
How do I find the moon phase on a date?
This moon phase calculator takes any day, month and year from 1900 to 2050, past or future, and draws the Moon for 12:00 UTC on that date, beside the calendar month it falls in. An hour is optional. Near a full or new Moon one hour hardly shows; near a quarter the lit fraction moves about 11 points in a day, so the hour matters there.
Can I check the moon phase for a future date?
Yes. The calculator works for future dates as for past ones, and the month's calendar sets each principal phase in its own day with its time, so the month's Full Moon and New Moon are there to read. The ephemeris is fitted to 1900 to 2050.
Why don't I need my location or time zone?
The Moon's phase is global. The lit fraction of the disc is the same from every point on Earth at a given instant, so no place is needed. The instant is 12:00 UTC on the date unless an hour is given, and the clock time of that instant differs by zone, which can put it on the neighbouring calendar day. A birth's Moon sign is different: the birthplace's time zone decides which instants of the Moon's path count, so the Moon sign calculator takes the place as well as the date.
What are the 8 moon phases?
New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter and Waning Crescent. The cycle runs about 29.5 days from one New Moon to the next, the lit fraction growing to the Full Moon and shrinking back to dark.
How accurate is this moon phase calculator?
The Sun and the Moon are placed by the house's ephemeris from the public-domain Meeus algorithms, and the phase is read from their separation. The lit fraction is good to the percent for the instant asked; the principal phases are found to the minute. Results are fitted to 1900 to 2050.
