It is a solar calendar based on the Hindu Vikram Samvat system and has been in use in Nepal for centuries. The Nepali calendar is approximately 56.7 years ahead of the Gregorian calendar and begins in the month of Baisakh (April/May). It consists of 12 months, with each month varying in length from 28 to 32 days.
