Vikram Samvat
Vikram Samvat (IAST: Vikrama Samvat; abbreviated VS), also known as the Vikrami calendar or, in Nepal, Nepal Sambat, is a Hindu calendar historically used in the Indian subcontinent and still used in several states. It is a lunisolar calendar, using twelve to thirteen lunar months each solar sidereal years. The year count of the Vikram Samvat calendar is usually 57 years ahead of the Gregorian calendar, except during January to April, when it is ahead by 56 years. The Vikram Samvat calendar should not be confused with the Nepali Bikram Sambat, a much more recent innovation.
