Convert a Bikram Sambat date to the Gregorian calendar — for passports, certificates, job forms and visa paperwork.
English (AD) Date
How to use
- Pick BS year, month, day: Use year 2000–2090 BS with the correct month length (29–32 days vary by year).
- Convert: Get the exact Gregorian date in YYYY-MM-DD plus readable format for forms.
- Verify: Cross-check with the Nepali Calendar page for tithi and weekday if the document needs it.
Example

Good to know
BS months do not align with Gregorian months and have variable lengths, so manual offset math fails. This tool uses the official BS↔AD mapping table.
FAQs
How do I convert a BS date to AD?
Enter the BS year, month and day above. The tool maps it through the official Bikram Sambat calendar table — no manual calculation needed.
What dates are supported?
BS years 2000–2090, which covers all practical citizenship, academic and passport dates. Earlier historical dates use different tables.
Is the conversion exact?
Yes within the supported range. BS month lengths are irregular, so always use a table-based converter like this rather than adding 56.7 years.
