Find the next full moon
Find events on or after the selected date, up to one year ahead. Choose an event to open that date in the calendar.
Downloads cover the displayed month. ICS includes its primary phase events, not daily phase samples or the finder list. Events do not block availability and have no reminders.

Plan with the Moon
Choose today, a birthday or a future date. Each daily illustration shows a schematic Moon at local noon, alongside its illuminated fraction. The calendar highlights calculated New Moon, First Quarter, Full Moon and Last Quarter events at their local times.
Does the Moon's phase depend on location?
At the same instant, the geocentric phase is the same worldwide. Your city controls the local date and clock. A Full Moon event near midnight can therefore fall on different calendar dates in different cities.
What does the Moon illustration show?
The disc shows the calculated illuminated fraction, with waxing light on the right and waning light on the left. It is a schematic, not a photograph or a prediction of the Moon's angle in your sky. Crescent and gibbous labels describe the shape; “Near” a primary phase means within one degree of its phase angle. Highlighted primary events give the calculated transition times.
How does the full moon finder work?
It searches calculated phase events from the beginning of the selected local date, including an event earlier today. It shows up to eight matches within one year and within 1900–2100. Calculations follow the Moon's changing motion rather than repeating a fixed 29.5-day cycle.
Time zones, dates and sources
Times use the city's IANA time zone and this browser's time-zone data, including daylight-saving changes. A skipped local date is marked unavailable. Supported dates are 1900–2100; future time-zone laws may change. City coordinates come from GeoNames. Calculations use locally hosted, MIT-licensed Astronomy Engine; lunar reference checks use US Naval Observatory data. Times are rounded to minutes.
What is saved?
Calculations run in your browser. City searches reach TimeCubby. Nothing is saved automatically, and no account or location permission is needed. A copied link includes your selected city, date and display settings.
