Nepali Date Converter: How to Convert BS to AD and AD to BS
Nepal uses the Bikram Sambat (BS) calendar for many everyday and official purposes, while international forms, software and databases often request Gregorian (AD) dates. A reliable BS to AD converter helps you move between the two formats without relying on a fixed year difference.

What is the difference between BS and AD dates?
Bikram Sambat is Nepal's official calendar. Its New Year begins around mid-April, and its months do not have the same fixed lengths as Gregorian months. Gregorian dates are used widely in international systems, passports, software and online services.
A BS year is roughly 56 to 57 years ahead of the corresponding AD year, but subtracting 56 or 57 is not a complete conversion. The exact day and month must be checked against calendar data.
How to convert a Nepali date to an English date
The converter uses calendar data with a defined supported range. It rejects dates outside that range instead of guessing.
- Open the PDFora Nepali Date Converter.
- Choose Nepali (BS) to English (AD).
- Enter the date in year-month-day order, for example 2083-01-01.
- Select Convert and review the Gregorian date and weekday.
- Copy the result only after checking that the original date was entered correctly.
How to convert AD to BS
Choose English (AD) to Nepali (BS), enter a valid Gregorian date such as 2026-04-14 and convert it. The result includes the BS year, month and day. You can also view the result using Nepali digits.
Use the date printed on the original document. Do not assume the date shown by a device is the same as the date printed on a certificate if the document was issued in a different time zone or calendar.
Common mistakes to avoid
- Do not convert by subtracting a fixed 56 or 57 years.
- Check whether the input is BS or AD before converting.
- Use year-month-day order to avoid swapping month and day.
- Check the supported year range before converting old historical dates.
- For official forms, compare the result with the source certificate or an authoritative Nepali calendar.

Frequently asked questions
Is BS the same as the Nepali calendar?
Yes. BS means Bikram Sambat, the calendar commonly used for Nepali dates (miti).
Can I convert 2083 BS to AD?
Yes, if the complete date falls within the converter's supported calendar range. Enter year, month and day rather than the year alone.
Can I convert AD to BS on my phone?
Yes. The converter is designed to work in a modern mobile browser as well as on a computer.
Is subtracting 56 years enough?
No. BS and AD year boundaries and month lengths differ. Use a calendar-data-based converter for the exact date.
