How This Converter Works

This isn't a rough estimate. We use official Nepali calendar data from the Nepal Calendar Determination Committee, mapping every day across both calendars from 2000 to 2090 BS.

🔍
1. Input Validation The system checks that your date exists in the Bikram Sambat calendar, accounting for variable month lengths (29 to 32 days).
📊
2. Day Count Calculation It calculates the total number of elapsed days from our reference epoch (2000 BS = April 14, 1943 AD).
🔄
3. Calendar Mapping Maps those days to the equivalent Gregorian (AD) or Bikram Sambat (BS) date instantly.
4. Result Display Shows the converted date with the weekday name in both English and Nepali.
Leap Year Cycles: The converter also handles Adhik Maas, the extra month that appears roughly every three years in the Nepali calendar to align lunar and solar cycles, ensuring accuracy even in leap years.

Common Conversion Examples

Nepali Date (BS) English Date (AD) Common Use Case
2050 Baisakh 15 April 28, 1993 Passport application birth date
2060 Jestha 5 May 19, 2003 Academic certificate conversion
2075 Ashadh 20 July 5, 2018 Government form submission
2080 Baisakh 1 April 14, 2023 Current year reference
Current Year Quick Reference:
  • 2081 BS = 2024-2025 AD
  • 2082 BS = 2025-2026 AD
  • 2083 BS = 2026-2027 AD

Why Nepali and English Dates Differ

Feature Gregorian Calendar (AD) Bikram Sambat (BS)
Type Solar (sun-based) Lunisolar (moon + sun)
Year start January 1 Mid-April (Baisakh)
Month length Fixed (28-31 days) Variable (29-32 days)
Year difference +56 to +57 years

The 56-57 year gap exists because the two calendars started from different historical points. The Nepali New Year begins in Baisakh (mid-April), which means if it's January 2025 AD, it's still late 2081 BS. Once April arrives, it becomes 2082 BS.

Note: Nepali months can have up to 32 days (especially Ashadh and Shrawan), something you won't find in the Gregorian calendar. This is why simple adding/subtracting doesn't work, meaning you need a proper converter.

How do I convert BS to AD and AD to BS?

What is Baisakh month in English?
Baisakh is the first month of the Nepali calendar, running from mid-April to mid-May. It marks the Nepali New Year and corresponds roughly to April/May in the Gregorian calendar.
How accurate is this converter?
This tool uses official Nepali calendar data from the Nepal Calendar Determination Committee. It accounts for variable month lengths (29-32 days) and Adhik Maas (the extra month that appears roughly every three years). The 2000-2090 BS range covers all practical needs.
What is Adhik Maas?
Adhik Maas is an extra month added to the Nepali calendar approximately every three years to align the lunar and solar cycles, similar to a leap year in the Gregorian calendar. This converter accounts for these adjustments.
Why do Nepali dates have different month lengths?
The Bikram Sambat calendar is lunisolar, meaning it follows the moon's cycles for months but the sun's cycle for the year. This creates months ranging from 29 to 32 days, depending on the year, to keep the calendar in sync with seasons.
How do I convert my birth date from Nepali to English?
Enter your Nepali birth date (year, month, day) in the converter above. The tool will instantly show the equivalent English date with day of the week. You can then copy the result for your documents.
