Tulu calendar

Tulu Calendar (also known as Varsa or Vorsa) is one of the oldest traditional Indian solar calendars, generally used in the regions of South-West Karnataka and Northern Kerala, India. The indigenous or Tulu speaking people of Tulu Nadu, and people who migrated from this region to other places, are the common followers of this calendar system.
