ad converter to bs

This tool converts an English (AD) date into the Nepali Bikram Sambat (BS) calendar used across Nepal for official, academic and cultural purposes. The BS calendar sits about 56 years and 8 months ahead of AD, but because each BS month can have 29 to 32 days and the pattern shifts every year, a fixed offset is never exact. The converter reads a verified calendar table so the Nepali date it returns matches the official patro to the day.

1. Enter the English (AD) year, for example 2026.
2. Select the English month, from January to December.
3. Choose the day of the month.
4. Press Convert to BS to see the Nepali year, month and day.
5. Copy or share the result, or swap to the BS to AD converter to reverse it.

• Recording a birth, wedding or event in the Nepali calendar for local paperwork, invitations or family records.
• Converting a certificate or contract issued abroad into the BS date a Nepali office requires.
• Finding out which BS year and month a Gregorian deadline, exam or appointment falls in.
• Checking your Nepali date of birth from a passport or foreign document that only lists the AD date.

September 12, 2026 (AD) converts to 2083 Bhadra 27 (BS). To see the whole month around a converted date, open the Nepali calendar, and to measure the span between two dates use the date difference calculator.
