This festival, taking place at Pashupati temple on the outskirts of Katmandu, is dedicated to the god Shiva. On the morning of Shivaratri day and also on proceeding days, thousands of worshippers make their way to the ancient and revered temple of Shiva, many of them undergoing one or more days of fasting. It is customary to offer gifts both in the temple itself and to the temple priests. The priests in turn, give back a small portion which is considered a gift from Lord Shiva and a sign of his blessing. While these religious rites continue until the evening, there is along military gun salute at Tundikhel parade ground in central Katmandu to acknowledge the important occasion. In the evening, His Majesty the King, accompanied by the Royal family, also pays homage at Pashupati temple.

As darkness falls, hundreds of wick lamps are lit around the temple vicinity while on the surrounding hills, bonfires are lit. Throughout the night, prayers, singing and chanting continue; many worshippers also take holy baths at three-hourly intervals. Bonfires are also lit at important crossroads and in village and town courtyards throughout the valley.
