Wisakha Puja Day is a very important day in the Buddhist tradition, for it was on this day that Prince Siddhattha Gotama was born, 35 years later became the Buddha, and in another 45 years, passed away into total Nibbana (Parinibbana). In each case, these events took place on the full-moon day in the Wisakha month (usually in May). It falls on the 15th day of the waxing moon in the 6th lunar month, i.e. full moon day.
This is the holiest of all the auspicious Buddhist religious days, marking the birth, enlightenment, and death of Lord Buddha. All over the country, people go to temples to listen to sermons by revered monks and make merit. Shortly after sunset, candlelit circumambulations take place around major temples.
