See the moon phase for any date and browse a full month of phases.
Displays the lunar phase for every day of any month, calculated from astronomical algorithms. Useful for gardeners (planting by moon phase), photographers (planning moonlit shoots), fishers (tide-related activity) and anyone curious about the night sky.
The phase calculation uses the synodic month (29.53 days) and is accurate to within a few hours for dates in the 20th and 21st centuries. It runs entirely in your browser — no external API is called.
Moon phases repeat in a cycle of about 29.5 days, so the same phase falls on a different calendar date each month. Full moons have popular names (Harvest Moon, Wolf Moon, etc.) that vary by cultural tradition.
