Bhutan is rich in cultural diversity and this richness is further enhanced by the wide variety of elaborate and colorful religious festivals that are celebrated throughout the country. Every village is known for their unique festival though the most widely known is the annual Tshechu, an annual religious festival.

Tshechu is a religious festival meaning "tenth day" held annually in various temples, monasteries and dzongs throughout the country.

The Tshechu is a religious event celebrated on tenth day of a month of the lunar calendar corresponding to the birthday of Guru Rimpoche (Guru Padmasambhava). However the exact month of the Tshechu varies from place to place and temple to temple.

Tshechus are grand events where entire communities come together to witness religious mask dances, receive blessings and socialize. In addition to the mask dances, tshechus also include colorful Bhutanese dances and other forms of entertainment.

It is believed that everyone must attend a Tshechu and witness the mask dances at least once to in order to receive blessings and wash away their sins. Every mask dance performed during a Tshechu has a special meaning or a story behind it and many are based on stories and incidents from as long ago as the 8th century, during the life of Guru Padmasambhava. In monasteries, the mask dances are performed by monks and in remote villages, they are performed jointly by monks and village men.

Two of the most popular Tshechus in the country are the Paro and Thimphu Tshechus in terms of participation and audience. Besides the locals, many tourists from across the world are attracted to these unique, colorful and exciting displays of traditional culture.

As the Tshechu begins, the villagers and the general populace dress in their finest clothes and congregate at their local temples and monasteries where these festivals take place. Tshechus are usually occasions to mark important events in the life of the second Buddha, the Indian/Pakistani Tantric master known as Guru Rinpoche or the Precious Master. Various mask dances are performed together with songs and dances for three days on average.

These religious celebrations are lively, high-spirited affairs during which people share meals of red rice, spicy pork, Ema Datshi and Momos (pork/beef dumplings) whilst drinking the heady traditional rice wine known as Ara. These occasions provide the villagers with a respite from the hard labor of their day to day lives and gives the community an opportunity to catch up with family and friends.
