About the Nepali BS to AD Date Converter

This Bikram Sambat to English date converter is built for anyone who needs to turn a Nepali date into its Gregorian (AD) equivalent quickly and accurately — students applying abroad, banks and insurance companies processing paperwork with mixed date formats, HR teams converting employee birth dates for international systems, and government offices coordinating with international partners who use the Gregorian calendar.

How the conversion works

Unlike a fixed offset ("just add 56 years"), Bikram Sambat is a lunisolar calendar where month lengths vary from year to year, so an accurate BS to AD date converter needs a real reference table of how many days are in each Nepali month, for each year. This tool uses exactly that — an official month-length data table covering BS 2000 to 2090 — checked against known reference dates such as 2000/01/01 BS equalling 14 April 1943 AD, so the output date and weekday are both reliable.

Common uses

• Converting a Nepali citizenship or birth certificate date to AD for a visa or study-abroad application
• Converting BS contract or invoice dates for international accounting
• Quickly checking what AD date a Nepali festival, deadline, or appointment falls on

For the reverse direction, see the English to Nepali (AD to BS) date converter, or browse a full month at once with the Nepali Bikram Sambat calendar.
