Buddha's Birthday is known as Vesak and is one of the major festivals of the year. It is celebrated on the first full moon day in May, or the fourth lunar month which usually occurs in May or during a lunar leap year, June. In some countries this has become an occasion to not only celebrate the birth but also the enlightenment and parinirvana of the Buddha. It celebrates the Buddhas enlightment, death and birth.

Magha Puja is an important religious festival celebrated by Buddhists in Thailand, Cambodia, and Laos on the full moon day of the third lunar month (this usually falls in February).

Also known as "Dhamma Day" celebrates the Buddha's first teaching on the full moon day of the 8th lunar month, approximately July.

This day is known as observance day, there are four holy days on the new moon, full moon, and quarter moon days every month.
