Reading the calendar

Because the synodic month (≈29.53 days) is shorter than most calendar months, full-moon dates creep earlier through the year and occasionally double up inside one month. In 2026 that happens twice — two full moons fall in the May 1 / May 31 window, making the second a seasonal 'blue moon'.

All times are the astronomical instant of the phase in Coordinated Universal Time (UTC). To get your local date, add or subtract your UTC offset; a 23:57 UTC full moon, for example, lands on the next calendar day across much of Asia.
