Poson Festival, celebrated on June 29, 2026, marks the historic introduction of Buddhism to Sri Lanka. This sacred full moon day, known as Poson Poya, is a public holiday across the island nation. Join in the spiritual observances, cultural festivities, and acts of generosity that define this important day.
For Poson Festival, the focus shifts from commercial deals to acts of generosity and community support, reflecting the Buddhist principles of Dana (giving). Many local businesses and individuals organize ‘Dansalas’ (alms-giving stalls) offering free food and drinks to pilgrims and the public. Organizations like the All Ceylon Buddhist Congress and Mahamevnawa Buddhist Monastery facilitate religious programs and charity drives. Look for opportunities to donate to Buddhist charities or participate in community service. We will update this page with specific community initiatives as June approaches.

Founded in 1988 by Merrill J. Fernando, Dilmah is a globally recognized Sri Lankan tea brand. Deeply committed to ethical practices and local communities, Dilmah often supports cultural events and initiatives that resonate with Sri Lankan heritage.

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.
