Tshechu (Dzongkha: ཚེས་བཅུ།, literally “day ten”) are annual religious Bhutanese festivals held in each district or dzongkhag of Bhutan on the tenth day of a month of the lunar Tibetan calendar. The month depends on the place. Tshechus are religious festivals of the Drukpa Lineage of the Kagyu school of Tibetan Buddhism.
Tshechus are large social gatherings, which perform the function of social bonding among people of remote and spread-out villages. Large markets also congregate at the fair locations, leading to brisk commerce. The Thimphutshechu and tha Paro tshechu are among the biggest of the tshechus in terms of participation and audience.
