About Nepali Date Conversion (BS ⇄ AD)
Nepal officially uses the Bikram Sambat (BS) calendar. Government forms, documents and festivals use BS dates, while visas, international documents and everyday digital life often use the AD (English/Gregorian) calendar — so converting between them is something Nepalis do constantly.
The 12 Nepali months are बैशाख, जेठ, असार, साउन, भदौ, असोज, कार्तिक, मंसिर, पुष, माघ, फागुन, चैत्र. Unlike the English calendar, each Nepali month has 29 to 32 days, and the length varies year to year — which is why an accurate lookup (not a fixed formula) is needed.
