What Is AD to BS Date Conversion?
AD to BS conversion means changing a date from the Gregorian calendar into its equivalent date in the Bikram Sambat calendar.
AD is a traditional abbreviation for Anno Domini, associated with the Gregorian calendar. This is the calendar used by most international websites, smartphones, travel services, and digital applications.
BS stands for Bikram Sambat. It is Nepal’s principal civil calendar and is widely used for government records, education, local businesses, festivals, and everyday activities.
AD Calendar
The Gregorian calendar begins on January 1. It is widely used internationally for business, travel, education, and technology.
BS Calendar
The Bikram Sambat calendar usually begins its New Year in mid-April and is commonly used throughout Nepal.
For example, you may know a birthday as an English date but want to find its Nepali calendar equivalent. An AD to BS converter helps you identify the corresponding Bikram Sambat year, month, and day.

Understanding the Difference Between AD and BS
The Gregorian and Bikram Sambat calendars do not begin their years on the same date. The Gregorian New Year starts on January 1, whereas the Nepali New Year usually begins in mid-April.
Because of this difference, one Gregorian year overlaps parts of two Bikram Sambat years. The exact BS date depends on the complete English year, month, and day.
| Feature | AD Calendar | BS Calendar |
|---|---|---|
| Full name | Gregorian Calendar | Bikram Sambat |
| Common name | English Date | Nepali Date |
| Year begins | January 1 | Usually mid-April |
| Months | 12 | 12 |
| Month length | Mostly fixed | Varies by year |
| Common use | International activities | Nepal’s civil and cultural activities |
Names of the 12 Nepali Months
The Bikram Sambat calendar has twelve commonly used months. Knowing their names helps you understand the result displayed by an AD to BS converter.
- Baisakh (बैशाख)
- Jestha (जेठ)
- Ashadh (असार)
- Shrawan (श्रावण)
- Bhadra (भदौ)
- Ashwin (असोज)
- Kartik (कात्तिक)
- Mangsir (मंसिर)
- Poush (पुष)
- Magh (माघ)
- Falgun (फागुन)
- Chaitra (चैत)
Unlike the Gregorian calendar, Nepali months do not all have an identical number of days. Their lengths vary according to the year. This is one reason why an exact date conversion needs suitable calendar data.
Can You Convert AD to BS by Adding 56 or 57 Years?
You may have heard that the Bikram Sambat year is approximately 56 or 57 years ahead of the Gregorian year. This is a useful general comparison, but it is not an exact conversion formula.
Simply adding 56 or 57 to an AD year will not tell you the correct Nepali month and day. The two calendars begin their years at different times, and their month structures are different.
Why Do People Convert English Dates into Nepali Dates?
1. Finding Nepali Birthday Dates
Many people know their birth date in the Gregorian calendar but prefer to celebrate their birthdays according to the Nepali calendar. AD to BS conversion helps identify the corresponding BS date.
2. Preparing Family Celebrations
Families may use Nepali dates for birthdays, anniversaries, gatherings, and other special occasions. Converting an English date can help everyone coordinate their plans.
3. Understanding Travel and Booking Dates
International flight tickets, hotel bookings, and travel applications generally use Gregorian dates. Converting a date into BS can make it easier to understand and record the same event in the Nepali calendar.
4. Maintaining School and Personal Records
Students, parents, and teachers may need to compare dates across different calendar systems. A converter can help when reviewing records or organizing personal schedules.
5. Working With Business Documents
Businesses in Nepal sometimes work with international partners who use Gregorian dates. Converting dates can make scheduling and record management easier.
6. Planning Events in Nepal
People may want to understand an English event date in the Nepali calendar before arranging meetings, family gatherings, or community activities.
7. Helping Nepali People Living Abroad
Nepali communities overseas often use international calendars for work and education while maintaining Nepali cultural traditions. Date conversion helps them coordinate personal events with relatives in Nepal.
How Accurate Is an Online AD to BS Converter?
The accuracy of a date converter depends on the calendar data it uses, the dates it supports, and how its conversion system is implemented.
A suitable converter should account for the relationship between Gregorian dates and the actual Bikram Sambat calendar. It should not rely only on a rough year difference.
Check the Complete Date
Always enter the correct Gregorian year, month, and day. A mistake in any one of these fields can produce an unexpected result.
Check the Supported Date Range
Some converters may support only selected years. If you are converting an older historical date, check whether the tool includes that period.
Verify Important Dates
If the converted date will be used for a passport, visa, legal document, academic certificate, financial record, or government application, compare it with the original records and follow the relevant authority’s instructions.
Understand Festival Dates Separately
A basic AD to BS converter translates civil calendar dates. It does not necessarily calculate lunar tithi, auspicious times, or religious observances. For those purposes, consult a suitable Nepali Patro or Panchang.
Common Mistakes to Avoid During AD to BS Conversion
- Entering the wrong year: Check the original date before starting the conversion.
- Selecting the wrong month: Confirm the English month carefully.
- Entering an invalid day: Make sure the selected day exists in that Gregorian month.
- Ignoring leap years: Remember that February has 29 days in a Gregorian leap year.
- Using a fixed year difference: Adding 56 or 57 years is not an exact date conversion method.
- Assuming every tool supports every year: Check the converter’s supported date range.
- Using an unchecked result for official paperwork: Verify important dates against original records and relevant authorities.
