Generally, the people of Limbu. Rai and Sunware (commonly known as Kiratis) celebrate Ubhauli and Udhauli festival. It is believed that there are two phases in one year – that are a Ubauli (Going up) and Udhuali (Going down) While the Ubhauli puja is usually conducted during the month of March and April (belief of onset of summer); Udhauli puja is a celebration of descending of season and is conducted during the month of November indicating the onset of winter season. It is believed that from November the winter season starts where people, birds, and animals migrate from cold regions to warmer regions. Udhauli and Ubhauli festivals are conducted in two different seasons – one in summer and the other one in winter- of the year. Kiratis are believed to be the worshipers of nature and agriculture being the sustenance of this community, the Kirats celebrate the Udhauli festival to thank Mother Nature for providing them with bountiful harvest during the current season. During the Ubhuali festival, as it marks the time of the year for cultivation, they pray to Mother Nature for timely rain, healthy crops and protection from natural calamities. In short, Ubhauli marks the beginning of cultivation, and Udhauli marks the harvest period. Although, in the past, Udhuali and Ubhauli festivals were conducted separately, the community today has started conducting these two festivals at one go in the month of March and April, calling this festival as Udhauli Ubhauli Puja. This community festival is conducted at the Diana River. This festival brings together all the people in the limbu community to observe a ritual of praying for a timely rain, good harvest and asking for good harvest at the end of the year. When: In the past, their ancestors used to celebrate Udhauli and Ubhauli puja in two different seasons (summer and winter) of the year. While Udhauli puja used to be conducted in the months of November and December, Ubhauli Puja was conducted in the months of March and April. However, with modernization and globalization, it has become difficult for the community to gather twice a year, they have started conducting this Udhauli and Ubhauli puja at the same time between March and April Month on any of the suitable days – Fridays and Saturdays, thus called this festival as Udhauli Ubhauli Puja. This festival is performed for a day. Where: Today, Udhaulu Ubhauli Puja is performed annually by the bank of River Diana. The reason why they perform this puja at the river is they being the worshiper of nature, they believe that the river is clean and is occupied by tutelary deities. People of the community gather together every year to pay homage to their deities, and pray for timely rain, good cultivation and bountiful harvest. Number of Performers: A paw initiates the festival with the help of one helper. It is said that the helper should be someone who would be able to understand the language of the initiator in a state of trance. The community makes merry, praying simultaneously for a smooth and successful entire crop cycle period starting from sowing seeds to harvest of the crop and protection from natural calamities.
