Adhi Poson Full Moon Poya 2026
What this means for your trip
Alcohol ban. This is the EXTRA (adhi) Poya of the 2026 intercalary year — an additional full-moon holiday that calendars assuming a normal twelve-Poya year miss entirely. Standard Poya closures island-wide. Poson proper follows on 29 June.
Why Poya dates are transcribed, not calculated
A Poya day is whichever calendar day the Government Gazette declares, and that is not a pure function of the full-moon instant. In 2026 the full moon of 3 January was gazetted as 3 January, while the full moon of 3 March was gazetted as 2 March. Any rule of the form “full moon date, minus one if it falls before a given hour” fits a single year and then quietly breaks. Every date on OneCeylon comes from the gazette and is cross-checked against a computed full moon to catch transcription errors.
