About the converter
This converter uses the same accurate Bikram Sambat (B.S.) calendar engine as the Patro calendar. Enter a date on either side and the other updates instantly, so you can check aja kati gate, convert birthdays, important days or plan around Nepali festivals against the Gregorian calendar with confidence.

Bikram Sambat is the official calendar of Nepal - a lunisolar calendar that runs roughly 56 years and 8.5 months ahead of the Gregorian (AD) calendar. The exact gap shifts slightly depending on the date, since the Nepali New Year starts in mid-April rather than January 1.
Enter the Bikram Sambat date (year, month, day) into the converter above, and the corresponding Gregorian (AD) date will appear instantly. You can also convert the other way - AD to BS - by switching the direction toggle.
Bikram Sambat is a lunisolar calendar tied to the solar year but adjusted using lunar months, so its new year (1 Baisakh) falls around mid-April in the Gregorian calendar rather than January 1.
Nepali months don't have a fixed number of days like Gregorian months - they range from 29 to 32 days and can vary slightly from year to year, based on the lunisolar calculations.
"Aja kati gate" means "what is today's date" in Nepali, referring to the current date on the Bikram Sambat calendar. You can check it directly on the Patro calendar homepage.

Yes, in a modified form. Similar Vikram Samvat-based calendars are also used in parts of India and neighboring regions for religious and cultural purposes, though Nepal is the only country where it's the official national calendar.
