How often is there a full moon?
A complete lunar cycle lasts about 29.53 days on average. That is why there is a little under a month between two full moons, and most years have twelve, occasionally thirteen full moons. The exact moment shifts from month to month, so it is worth checking the precise date.
Why the time differs around the world
The astronomical full moon happens at the same instant everywhere on Earth. But because every time zone shows a different local time, the same full moon can occur in the morning in Switzerland and the previous evening in America. The times on this page are for Switzerland (CET/CEST).
The full moon in the moon calendar
Many traditions surround the full moon – advice for the garden, hair or rituals. These moon traditions are culturally widespread, but not scientifically proven. The moon-sign guidance can be found in the moon calendar.
