This is the day marked to remember the preaching of Lord Buddha who was born, enlightened and also left the world on this very day. Buddhism is the second most popular religion in Nepal. The day is celebrated throughout the valley. Swoyambhunath and Boudhanath stupas are prepared several days in advance for this day. Monasteries are cleaned, statues polished and new flags waft in the breeze. Many people in the Kathmandu valley put a new flag on their roofs on this day. In Patan, many people take part in a rpocession which circles the city with the big statue of Buddha. People also exhibit the Buddha's photos outside many of the House. On this day people go to the stupas before dawn, go around them and give offerings to the Buddha's images.
