Vesak — also spelled Wesak and known as Buddha Day — is the most sacred day in the Buddhist year. It commemorates the most important events in the life of the Buddha. Because it follows the lunar calendar, its date varies; in 2026 many countries observe it around late May. Here's its meaning and history.
See the Vesak holiday page for the exact date, or the global holiday calendar.
What does Vesak commemorate?
Vesak marks three key events in the life of Siddhartha Gautama, the Buddha — traditionally believed to have occurred on the same full-moon day:
- His birth (in Lumbini, in present-day Nepal),
- His enlightenment (nirvana) under the Bodhi tree at Bodh Gaya, and
- His passing away (parinirvana).
This is why Vesak is sometimes called the celebration of the Buddha's "birth, enlightenment, and death."
Why the date changes each year
Vesak falls on the full moon of the lunar month of Vesakha (usually April or May). Because it's based on the lunar calendar, the date shifts each year — and different Buddhist traditions and countries may observe it on different days. Always check the holiday page for the date in a specific country and year.
In 1999, the United Nations recognised Vesak internationally, acknowledging the contribution of Buddhism to humanity.
How Vesak is observed
- Visiting temples, offering flowers, candles and incense.
- Meditation and observing the Buddhist precepts.
- Acts of generosity and kindness — giving to those in need, freeing caged birds, and vegetarian meals.
- Lanterns and processions in many countries.
Customs vary across Sri Lanka, Thailand, Myanmar, Indonesia (at Borobudur), Singapore, Malaysia, India, Nepal and beyond.
