The time is the moment the Moon is exactly opposite the Sun. The Moon looks full for a night or so either side, so if the time is early in the morning, the night before will look just as full. For another time zone, subtract 7 hours to get UTC, then add your own offset.

How we worked it out
The dates are computed, not copied. We use the lunar phase method from Jean Meeus's Astronomical Algorithms (chapter 49): the mean time of each full moon plus its periodic and planetary corrections, converted from Terrestrial Time to Universal Time and then to Bangkok time. The method is accurate to within about a minute, so a full moon very close to midnight could land on the neighbouring date in other sources.
Full moon days and Buddhist holy days
In Thailand, Buddhist holy days (วันพระ, wan phra) follow the Thai lunar calendar, which counts whole days in months of 29 and 30 days. Because of that, a holy day can fall a day before or after the astronomical full moon in this table. Holidays such as Makha Bucha, Visakha Bucha and Asarnha Bucha are set by that calendar and announced officially, so check the official Thai calendar rather than this table for them.
Seasons in Expo Tycoon follow the full moon
Expo Tycoon is a free trade-show tycoon game for phones, made in Bangkok by Messe Asia, a real exhibition organiser. Its seasons follow this calendar: each season runs from the day after one full moon to the next full-moon day, and ends with the Grand Expo, a finale over the three nights up to the full moon where your best show score goes on the season board.
Season 1 runs from 27 October to the Loy Krathong full moon on 24 November 2026. After that, every row in the table above is the last night of a season. The game guide explains how seasons and the Grand Expo work.
