The Poson Festival is celebrated on June 29 and marks the historic introduction of Buddhism to Sri Lanka. Known as Poson Poya, this sacred full moon day is a public holiday across the island. The festival is characterized by spiritual observances, cultural festivities, and acts of generosity, reflecting the Buddhist principles of Dana (giving). Many local businesses and individuals organize 'Dansalas' (alms-giving stalls) that offer free food and drinks to pilgrims and the public. Organizations such as the All Ceylon Buddhist Congress and Mahamevnawa Buddhist Monastery facilitate religious programs and charity drives during this time. Participants often visit local temples for sermons and meditation, while communities come together to engage in acts of compassion and support. The festival serves as a significant occasion for promoting Buddhist culture and community welfare.
