Absolutely! The Tsechus (festivals) follow the Buddhist lunar calendar and agricultural seasons. Spring: Paro Tsechu (March-April). Autumn: Thimphu Tsechu (September-October). Winter: Punakha festivals (February-March). Each season offers its own unique celebrations.

Does climate change affect Bhutan?

Bhutan feels the effects of global warming: more irregular monsoons, melting Himalayan glaciers, and seasonal temperature variations. However, the country remains a model of sustainability with a strict environmental policy and a negative carbon footprint.
