Numerous festivals called Tshechus(10th day) are held annually throughout Bhutan to commemorate the Guru Rinpoche (Guru Padmasambhava). Festivals are held annually throughout the country in dzongs and monasteries, and although the most popular events held in Thimpu, Paro and Bumthang fall in spring and fall, festival dates in lesser-known locations vary widely. It is best to confirm festival dates with the Tourism Council of Bhutan before scheduling your trip. Typically lasting between 3 and 5 days, Tsechus are uproarious affairs characterized by traditional dance and religious ceremonies, some of which date back to the early Middle Ages.
