What the Bikram Sambat calendar is
Bikram Sambat, often written as B.S. or Vikram Samvat, is the official civil calendar used in Nepal for many government, school, festival, and everyday references. It is usually about 56 years and 8 to 9 months ahead of the Gregorian calendar, but exact conversion is table-based and should be checked with a calendar or converter.
Nepali New Year and conversion
Baisakh 1 is Nepali New Year. For 2083 B.S., UnitedSewa's converter maps Baisakh 1 to April 14, 2026, and Hamro Patro's 2083 holiday calendar lists the same date. Do not convert B.S. dates by simply adding a fixed number of years; month lengths and festival dates need a patro or converter.
Festival dates
Many festival dates are tied to lunar tithi, so their Gregorian dates move each year and may vary by region or time zone. For planning in the U.S., use the UnitedSewa calendar when the occurrence is verified, then confirm the exact program date with the local organizer.
Why this matters in the diaspora
You may see B.S. dates on Nepali documents, school records, invitations, public holiday lists, and community event flyers. When a U.S. office asks for a Gregorian date, convert the date and keep a copy of the source you used.
