Free Nepali (Bikram Sambat) date converter

Nepal officially uses the Bikram Sambat (BS) calendar, which is about 56 years and 8 months ahead of the Gregorian (AD) calendar. Unlike Gregorian months, BS month lengths vary from 29 to 32 days and are set by Nepal's official calendar — so accurate conversion needs a real month-length table, not a rough formula. This BS to AD date converter uses a full 101-year table (BS 2000–2100) and converts both ways with the correct day of the week.

Use it to convert your citizenship, passport or academic dates between BS and AD, check what day of the week a Nepali date falls on (बार), or see today's date in both calendars at a glance. Popular with students filling Loksewa and job forms, and anyone dealing with official documents in Nepal.

How to use

  1. For BS → AD: pick the Bikram Sambat year, month and day, then tap "Convert to AD".
  2. For AD → BS: pick a Gregorian date from the calendar picker, then tap "Convert to BS".
  3. The result shows the converted date plus the day of the week in English and Nepali (e.g. Monday · सोमबार).

Accuracy note: BS month lengths follow Nepal's official calendar. This tool covers BS 2000-01-01 to 2100-12-30 and has been checked against official Nepali New Year dates. For critical legal documents, always cross-check with an official patro.
