Nepal Sambat
Nepal Sambat (Newar: š£š¾š„šµš® š³š©šš§šā, nepÄla samvat, meaning "Nepal Era") is the lunisolar calendar used by the Newar people of Nepal. It was the official calendar of Nepal since its inception on 20 October 879 till the end of the Malla dynasty in 1769. During the period, Nepal Sambat appeared on coins, stone and copper plate inscriptions, royal decrees, chronicles, Hindu and Buddhist manuscripts, legal documents and correspondence. After the conquest of Nepal by the Shahs in 1769, the official calendar of the country was replaced with Shaka era and then later by the Bikram Samvat.
The calendar still holds cultural significance in Nepal, especially among the Newar people, whose festivals are based on this calendar system. Owing to its cultural and historical significance, the government of Nepal declared to include Nepal Sambat in official government documents alongside Vikram Sambat since 11 November 2023.
The origin of Nepal Sambat is often the subject of folklore like that of Sankhadhar Sakhwa, a semi-legendary figure who often appears in folklore as the progenitor of the calendar system. However, its historical origins still remain a mystery.
