// AD ↔ BS Calendar System Differences
Bikram Sambat (BS) is Nepal's official solar-luni calendar system. It is approximately 56 years and 8.5 months ahead of the Gregorian calendar (AD). Since month lengths in BS vary based on the Sun's astronomical transit into different zodiac signs, the number of days in each month ranges dynamically from 29 to 32 days, requiring pre-computed tabular offsets for exact calculations.

How do I convert AD date to BS (Bikram Sambat)?
Enter the AD (English Gregorian) date in the converter, select 'AD to BS', and click convert. The Bikram Sambat calendar is approximately 56 years and 8.5 months ahead of AD.
What is the difference between the AD and BS calendars?
The Gregorian calendar (AD) is a solar calendar based on the tropical year, whereas Bikram Sambat (BS) is a solar-luni calendar used officially in Nepal, which shifts months according to solar transits.
What year is 2026 AD in the Nepali calendar (BS)?
2026 AD corresponds to 2082 BS (until mid-April) and 2083 BS (after Baisakh 1, which marks the Nepali New Year).
When does the Nepali New Year start?
The Nepali New Year always begins on Baisakh 1, which usually falls on April 13 or April 14 in the Gregorian (AD) calendar.
What is the range of years supported by this date converter?
This digital date converter supports English AD dates from 1943 to 2033, and Nepali BS dates from 2000 BS to 2090 BS.
Why do some days vary by +/- 1 day in different calendars?
Since BS months have dynamic lengths determined by solar transits (ranging from 29 to 32 days), the exact conversion requires astronomical tables, leading to a potential 1-day variance in third-party calendars. This converter uses Nepal Standard Time (UTC+5:45) for exact alignment.
