The short version:
A Bikram Sambat (BS) year starts in mid-April, so each BS year covers parts of two English (AD) years. The quick rule: AD year = BS year − 57 from Baishakh to December, and BS year − 56 from January to Chaitra.
Need an exact date, not just the year?
Use the free BS to AD date converter — it gives the exact English date and weekday for any day.
BS to AD in one step
- A date in Baishakh to Poush (before 1 January): subtract 57. 2050 Shrawan → 1993.
- A date in Magh to Chaitra, or in Poush after 31 December: subtract 56. 2050 Magh → 1994.
- AD to BS works the other way: add 57 from mid-April to December, add 56 from January to mid-April.
The exact changeover days move by a day or two each year, so check dates close to mid-April or the New Year in the converter.
