BS vs AD: What You Need to Know

Bikram Sambat (BS) is Nepal's official calendar, running 56-57 years ahead of the Gregorian (AD) calendar. For example, 2082 BS corresponds to 2025-2026 AD.

Government forms typically ask for BS dates. International forms (passport, visa, university applications) usually require AD dates. This calculator handles both, so you can enter your date in either format and get the equivalent in the other calendar.

Quick conversion: Subtract approximately 56 years from a BS year to get the AD year. For precise conversion, use the calculator above, as BS months have varying lengths (29-32 days) that affect the exact date.

Practical Tips for Government Forms

Always verify with official sources before submitting. Requirements change, and offices may have specific formatting preferences.

For citizenship: Provide both BS and AD dates if the form allows. This shows thoroughness and reduces follow-up requests.

For SEE: Double-check that your school has your correct birth date on file. Discrepancies between school records and your actual DOB can cause registration issues.

For retirement: Government employees should confirm their retirement date with HR, as the 2025 rule change may affect your specific situation.

Save your calculation: Screenshot or note your results. If questioned, you can show how you determined your age.

Accuracy & Limitations

This calculator uses official Bikram Sambat calendar data covering 1658 BS to 2100 BS (1602 AD to 2044 AD). It accounts for month length variations in the BS calendar, which range from 29 to 32 days depending on the year.

However, always verify with government offices before submitting official documents. While our calculations are accurate based on standard calendar data, specific offices may have additional requirements or interpretation guidelines.
