Everything You Need to Know About Date Conversion
Converting dates between the Bikram Sambat (BS) and Gregorian (AD) systems is a common necessity for Nepalese people worldwide. Our tool uses a high-precision algorithm based on the official Nepali calendar rules to ensure your legal documents, birthdays, and anniversaries are perfectly synchronized.
Why is there a 56-year difference?
The Bikram Sambat era was founded by King Vikramaditya and is approximately 56 years, 8 months, and 17 days ahead of the Gregorian calendar. Since it follows the solar cycle with lunar influence, the number of days in each month varies each year, unlike the fixed Gregorian months.

Our converter handles leap years in both systems flawlessly. We support historical date lookup back to 1944 AD (2000 BS) and future planning up to 2094 AD (2150 BS), making it ideal for genealogy research and long-term project planning.
