About Bikram Sambat (BS) Calendar
Bikram Sambat (BS) is the official calendar of Nepal. It is a solar calendar based on ancient Hindu traditions. Unlike the Gregorian calendar (AD) which has fixed days per month, the BS calendar is dynamically calculated based on the movement of the sun, meaning the number of days in a month (usually 29 to 32) can change from year to year.

Frequently Asked Questions (FAQs)
How far apart are AD and BS calendars?
The Bikram Sambat calendar is approximately 56 years and 8.5 months ahead of the Gregorian calendar.
Why are there sometimes 32 days in a Nepali month?
Since the BS calendar is tied to the sun's position in different zodiac signs (Sankranti), and the earth's orbit is elliptical, it takes varying amounts of time to pass through each sign. This causes some months to extend to 31 or 32 days.
