Introduction

Nepal uses the Bikram Sambat (BS) calendar, which is approximately 56 years ahead of the Gregorian AD calendar. Converting between these two systems is essential for official documents, travel, and everyday planning.

What is Bikram Sambat?

Bikram Sambat is the official calendar of Nepal. It is a lunar-solar calendar that typically starts in mid-April. BS months have varying lengths — ranging from 29 to 32 days depending on the year (not a fixed 30/31 split) — so always rely on an official BS calendar rather than assuming a fixed month length. See the official Nepali calendar references via the Nepal government's calendar publications (commonly hosted alongside the Department of Printing (dop.gov.np) national calendar notices).

Why You Need to Convert

Many official documents in Nepal use BS dates, while international documents use AD dates. You may need to convert dates for:

  • Passport and visa applications
  • Academic certificates and transcripts
  • Legal documents and contracts
  • Travel planning and flight bookings
