How to Convert AD to BS

Converting a Gregorian (AD) date to the Bikram Sambat (BS) calendar is straightforward with this tool. Here’s how it works:

  1. 1Select the AD Year from the dropdown. Supported years are 1995 AD to 2033 AD.
  2. 2Select the AD Month. The day count automatically adjusts – Gregorian months have 28–31 days depending on the year.
  3. 3Select the AD Day and click Convert AD to BS.
  4. 4The equivalent BS date appears instantly, along with the day of the week.

Why Can’t You Just Add 57 to AD to Get BS?

A common shortcut is to add 57 to the AD year to get an approximate BS year – and while this gives the right year in many cases, it does not give you the correct month and day.

April 14, 2025 AD started on Baisakh 1, 2082 BS
December 31, 2025 AD falls in Poush, 2082 BS
So 2025 + 57 = 2082 … but only for dates after mid-April

Additionally, Nepali month lengths vary every year, meaning calculating the exact day from a Gregorian date makes it impossible to compute the exact day without a data table or a reliable API tool like ours.
