|---|---|---|
| Year starts | Baisakh 1, mid-April | 1 January |
| Month length | 29 to 32 days, varies by year | 28 to 31, fixed pattern |
| Year length | 365 or 366 days | 365 or 366 days |
| Determined by | Solar position, published in advance | Fixed arithmetic rule |
| Current gap | About 56 years and 8 months ahead | |

Where you will actually need this
- Passport and visa forms. Your citizenship certificate carries a BS birth date; most international forms want the Gregorian one.
- University applications abroad. Transcripts are issued in BS and usually need a converted equivalent attached.
- Contracts and deadlines. Nepali offices write dates in BS even when the counterparty works in AD.
- Family birthdays. A BS birthday falls on a different Gregorian date each year, which is why the two rarely line up.
Frequently asked questions
How far ahead of the English calendar is the Nepali one?
Bikram Sambat runs roughly 56 years and 8 and a half months ahead of the Gregorian calendar. The exact gap shifts because the two calendars start their years at different points.
Why can't the conversion be done with a formula?
Because Bikram Sambat month lengths are not fixed. A month can have 29, 30, 31 or 32 days, and which one it has is determined by solar position and published in advance rather than calculated by a rule. Every accurate converter works from a table, not an equation.
What date range does this cover?
2000 BS to 2090 BS, which is 1943 to 2033 in the Gregorian calendar. That covers every birth date currently in use on Nepali citizenship documents.
Can I use this for passport and visa forms?
It is accurate for the supported range, and the modern years have been checked against every published Nepali New Year date. For anything legally binding, still confirm against your citizenship certificate or an official Nepali patro.
When does the Nepali new year fall?
Baisakh 1 lands on 13 or 14 April in most years. It is a public holiday in Nepal.
