About AD to BS Conversion

How Does This Converter Work?

This converter uses the actual published Nepali calendar month-length data for every year in the supported range. Unlike approximate converters that add a fixed offset, Mero Sanjal handles the variable month lengths of the Bikram Sambat calendar precisely.

What date range is supported?

The converter supports AD dates from 1919-04-13 to 2044-04-12, covering BS years 1976 to 2100. Leap years are handled automatically.

Can I use this for official documents?

Yes. The conversion uses government-published calendar data and matches official records. Many Nepalis use this tool for visa applications, school admissions, and legal documents.

Is my data private?

Absolutely. All date conversions happen in your browser — no dates are sent to any server. Your data stays on your device.

Can I also convert BS to AD?

Yes! Use the toggle at the top to switch directions, or visit the BS to AD converter page directly.
