Unveiling the Origins of Bikram Sambat: A Historical Perspective from Nepal

Bikram Sambat is a scientific calendar based on the Surya Siddhanta. It is the oldest solar-based calendar in the world and Nepal's indigenous calendar. Various evidence indicates that King Vikramaditya of Battisputali, Kathmandu, was the one who introduced the Bikram Sambat currently in use in Nepal.

This calendar is used in Nepal for official work as well as religious and cultural activities. Religious and cultural festivals celebrated in Nepal are observed through the coordination of the lunar and solar calendars. The Nepal Panchanga Nirnayak Samiti coordinates both in the Nepali almanac.
