About the 2027 lunar calendar
The table above lists all thirteen lunar events of 2027 — the year contains either 12 or 13 of each phase depending on how the cycle aligns with January. Times are given in UTC so they are unambiguous worldwide; convert to your local zone, remembering that a 23:00 UTC full moon lands the next calendar day in the Americas and Asia-Pacific.
Why full moon dates shift every year
The lunar cycle (29.53 days) does not divide evenly into the calendar year (365.24 days), so lunar dates drift about 11 days earlier each solar year. That is why 'harvest moon' lands in September some years and early October in others, and why every lunar new year moves.
