Plan with the Lunar Calendar
Find upcoming phases and use the calendar as a gentle observation schedule.
Try the tool →Three small steps
Check the time zone
Choose how event times are displayed. A phase happens at one instant worldwide, but its calendar date can differ between time zones.
Narrow the list
Show all phases or filter to new or full moons. Read the phase label as well as any seasonal full-moon name.
Take one date with you
Download a calendar reminder for the event you want to observe. Adding it to your calendar is your choice; this page does not connect to or change your calendar account.
Words to recognize
- Phase instant
- The calculated time of a new moon, full moon, or quarter.
- Full-moon name
- A seasonal naming tradition; names differ across places and cultures.
- Calendar file

try what you learned
Two visitors see different dates for the same full moon. Why might both be right?
Take it into practice
- Would a short sky walk fit this date?
- Which season do you actually notice where you live?
Art, sources & approach
Event times are calculated with Astronomy Engine. Seasonal names are presented as folk-almanac language, not universal names. Calendar downloads are generated locally from the event shown.
