Why Accurate Date Conversion Matters
Incorrect date conversion is one of the most common issues faced by Nepalis applying for:
- Nepali Passport
- DV Lottery (Diversity Visa Program)
- Student visa and university applications
- Citizenship and birth certificate verification
- Work permits and immigration forms
Even a one-day difference can create problems during document verification. That is why using a reliable converter is essential.
How to Convert BS Date to AD (Step-by-Step)
- Go to the Nepali Date Converter.
- Select the BS → AD option.
- Choose the Year, Month, and Day in Bikram Sambat.
- The correct Gregorian (AD) date will appear instantly along with the weekday.
Example:
BS Date: 15 Baisakh 2055
Converted AD Date: 28 April 1998
Common Mistakes to Avoid
- Subtracting 56 or 57 years directly — This method is inaccurate because Nepali months have varying lengths and the new year starts in mid-April.
- Confusing similar-sounding month names.
- Using outdated or incorrect online converters.
- Writing the date in the wrong format (DD/MM/YYYY vs MM/DD/YYYY) on international forms.

Frequently Asked Questions
How do I convert my BS birth date to AD for a passport?
Use a reliable BS to AD converter. Enter your date of birth as written on your citizenship or birth certificate, and use the converted Gregorian date on the passport application form.
Can I use this converter for DV Lottery?
Yes. The DV Lottery form requires your date of birth in the Gregorian (AD) calendar. Always convert carefully and double-check the result.
Why is simply subtracting 56 years wrong?
Because the Bikram Sambat new year starts around mid-April, and Nepali months have different lengths every year. A proper mapped conversion table is required for accuracy.
What date format should I use on international forms?
Most international forms (including DV Lottery and many visa applications) prefer MM/DD/YYYY or clearly labeled month names. Always follow the specific instructions on the form.
Is your Nepali Date Converter accurate?
Yes. Our converter uses verified calendar data covering B.S. 1970 to B.S. 2100 and is regularly updated.
Final Advice
Always keep both the original BS date (from your official Nepali documents) and the correctly converted AD date. When in doubt, use a trusted converter and cross-verify important dates.
