Wesak
This is a Buddhist festival.

Wesak (or Visakha) is on the full moon  day of the month Visakha- usually in May or June.

 At this festival a large act of worship, or Puja, happens. This is    why the festival is sometimes called Visakha Puja. Often captured birds, fish or turtles (if you have them!) are released to show the  love and compassion of Buddha. Homes and Temples are hung   with lanterns and flowers, and flower offerings are placed before the statue of Buddha.In the evening, processions go round the temples with incense sticks, lit candles and flowers, before the day ends with a night-long sermon which tells of the great teachings of Buddha.

The teachings of the Buddha and the order of Monks which he founded are the heart of Buddhism. The linking of the three main events of Buddha's life on one day gives an occasion for remembering his teaching.
