Source-derived summary

Poson, also known as Poson Poya, is an annual festival held by Sri Lankan Buddhists celebrating the arrival of Buddhism in Sri Lanka in the 3rd century BC. The festival is the most important Poya (full moon) holiday of the year and the second most important Buddhist holiday of the year, being surpassed in importance by Vesak. Poson is celebrated throughout the island, with the most important ceremonies of the festival being held in Anuradhapura and Mihintale. The festival is held in early June, coinciding with the June full moon.

Festival

Poson is celebrated to commemorate the introduction of Buddhism to Sri Lanka by Mahinda Thero in 236 BC. The focal point of the religious festival is the Buddhist monastic complex on the mountain of Mihintale, where Arahath Mahinda Thero preached Buddhism to one of the kings, king Devanampiyatissa, of Sri Lanka. Celebrations are also centered around Buddhist sites in Anuradhapura, which was one of the first cities in Sri Lanka to convert to Buddhism. During Poson, these two locations attract thousands of pilgrims from across Sri Lanka. These pilgrims dress in white and worship at the spiritual locales. Many of the most devoted pilgrims spend hours in quiet contemplation to honor the traditions of Buddhism.

The Poson Festival is celebrated throughout the island, where, huge electronically lit Pandols are showcased in various city centres, dansals (free food stores organized by communities) are organized. Houses are decorated with Lanterns, and lights to commemorate the day in a festive manner.

Editorial analysis

Why this record matters

“Poson” is worth following because a concise public description often conceals a longer documentary argument. Here, Poson, Buddhist and festival provides the most credible route into that argument.

Evidence profile

Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Apr 28, 2026. The linked authority identifier is Q48733901. None of the 0 selected statements returned an explicit reference.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
