When is Bak Poya?
In 2026, Bak Poya falls on Wednesday, April 1, 2026. It is classified here as a Sri Lankan public holiday.
History of Bak Poya
Bak Full Moon Poya Day falls close to the Sinhala and Tamil New Year season and is associated with the Buddha’s second visit to Sri Lanka in Buddhist tradition. The day sits at an interesting meeting point in the calendar: a Buddhist full-moon holiday immediately before one of the island’s most widely shared seasonal celebrations.
For devotees, it is a day of temple observance and reflection. For families preparing for the new year, it can also be part of a busy period of cleaning, cooking and travel. As with every Poya day, the full-moon date is approved annually rather than fixed in the Gregorian calendar.
Bak Full Moon Poya Day is legally a public and bank holiday under Sri Lanka's approved annual calendar. The 2026 date is April 1; outside 2026, the lunar estimate on this site remains provisional until the Minister's calendar and any Gazette variation are published. Shop and office employees are entitled to a Full Moon Poya holiday, but the governing Act does not create an extra day in lieu when Poya coincides with a weekly holiday or another statutory holiday. Banks close, government services reduce, and tourism or essential services may continue with lawful staffing. Licensed alcohol sales are restricted on Poya days, while local rules also affect meat sales and entertainment; visitors should follow current notices rather than assume every business closes.
How Bak Poya is observed
