Poson Festival – June 10, 2025

This year Poson Festival will be celebrated on June 10. The day, also known as Poson Festival, is a public holiday in Sri Lanka. It falls on the full moon day of Poson, which is the seventh month of the Sinhalese calendar. The holiday depends on natural occurrences and its date varies, although it is commonly celebrated in June. It is a highly religious event that commemorates the introduction of Buddhism to Sri Lanka. Buddhists celebrate the day with music, dancing, and relating stories by giving away food and tea. Poson Day is second only in importance to Vesak in Sri Lanka.

History of Poson Festival

Poson Festival marks the introduction of Buddhism to Sri Lanka by a Buddhist monk called Arahat Mahinda in 236 B.C. One of the central points of the event is a Buddhist monastery on the mountain Mihintale, where Mahinda converted the King of Sri Lanka. His conversion to Buddhism led to the construction of many Buddhist sites and learning centers around the capital. It helped form an official connection between Buddhism and Sri Lanka. The relationship contributed to the spread of Buddhism on the island but resulted in ethnic tensions and hostilities, which developed into a major civil war in 1983. The conflict lasted for over 20 years, resulting in many casualties on both sides.

Sri Lanka is said to maintain the oldest Buddhist civilization. This religion, however, has had moments of descent, one being the time Sri Lanka was a British Colony. Heightened Christian missionary activities and British rule diminished the prominence and influence of Buddhist monks and conventional learning centers. Faithful restorationists fought to restore Buddhism’s place on the island and expel the British.

Sri Lanka’s independence was declared in 1948, and in May 1957, the country held a national event to commemorate its 2,500-year anniversary of Buddhism. The religious zeal that preceded the event led to the creation of new Buddhist institutions and centers of knowledge, restoring Buddhism to the heart of the nation. Poson Poya celebrations center around Buddhist sites in the mountains of Mihintale and Anuradhapura. During Poson, thousands of pilgrims from Sri Lanka flock to these locations. They dress in white and worship in the spiritual areas.
