As someone who has always been fascinated by different cultures and their traditions, I was intrigued to learn about the Tibetan Calendar and the various festivals and events celebrated in it. The Tibetan Calendar, also known as the Buddhist Calendar, is a lunisolar calendar used in Tibet, Bhutan, Nepal, and Mongolia. It is based on the cycles of the moon and the sun, and each year is divided into 12 or 13 lunar months.
