How to Convert AD to BS (English to Nepali Date)

Converting an AD (Anno Domini / Gregorian calendar) date to BS (Bikram Sambat / Nepali calendar) is one of the most frequent date-related tasks for people in Nepal. Whether you are filling in a government form, checking a property document, converting your date of birth for a citizenship application, or verifying a festival date — AD to BS conversion comes up constantly.

Using the converter above:

  1. Select the AD to BS tab

  2. Enter your AD date — day, month, and year

  3. Click Convert

  4. Your exact BS date appears instantly — day, Nepali month name, and BS year

Quick reference: To roughly convert an AD year to BS, add 56 or 57 to the AD year. For example, 2026 AD is approximately 2082/2083 BS. The exact year depends on the month — dates before Baisakh (mid-April) fall in one BS year, dates from Baisakh onwards fall in the next. Use the converter above for exact results.

How to Convert BS to AD (Nepali to English Date)

BS to AD conversion is equally common — especially when dealing with international documents, visa applications, bank forms, university admissions abroad, or any situation where the receiving party uses the Gregorian calendar.

Using the converter above:

  1. Select the BS to AD tab

  2. Select the BS year, BS month (Baisakh through Chaitra), and BS day

  3. Click Convert

The 12 Months of the Nepali Calendar (Bikram Sambat)

The Nepali calendar (BS) has 12 months just like the Gregorian calendar — but they do not align with the English months. Each BS month overlaps two English calendar months. Here are all 12 Nepali months with their approximate AD equivalent and typical number of days:

BS Month Number Nepali Month Name Approx. AD Equivalent Typical Days
1 Baisakh Mid-April to Mid-May 30 or 31
2 Jestha Mid-May to Mid-June 31 or 32
3 Ashadh Mid-June to Mid-July 31 or 32
4 Shrawan Mid-July to Mid-August 31 or 32
5 Bhadra Mid-August to Mid-September 31 or 32
6 Ashwin Mid-September to Mid-October 29 or 30
7 Kartik Mid-October to Mid-November 29 or 30
8 Mangsir Mid-November to Mid-December 29 or 30
9 Poush Mid-December to Mid-January 29 or 30
10 Magh Mid-January to Mid-February 29 or 30
11 Falgun Mid-February to Mid-March 29 or 30
12 Chaitra Mid-March to Mid-April 29 or 30

An important quirk of the Nepali calendar: unlike the Gregorian calendar where every month has a fixed number of days, BS months vary from year to year. A month that has 31 days one year may have 30 days the next. This is why manual conversion is unreliable — only a converter that uses the actual BS calendar data table for each year will give accurate results.

What is Today’s Date in Nepali Calendar (BS)?

Today in AD is June 01, 2026. The equivalent date in Nepali Bikram Sambat calendar is Jestha 18, 2083 BS.

Nepal is currently in fiscal year 2082/83, which runs from Shrawan 1, 2082 BS (mid-July 2025) to Ashadh end, 2083 BS (mid-July 2026). The new fiscal year 2083/84 begins Shrawan 1, 2083 BS (mid-July 2026).

Calendar System Today’s Date
AD (Gregorian) June 01, 2026
BS (Bikram Sambat) Jestha 18, 2083
Nepal Fiscal Year 2082/83 (ending mid-July 2026)

How Does the Nepali Date Converter Work?

The Nepali date converter uses a reference data table of the actual Bikram Sambat calendar — a lookup table that maps every BS date to its corresponding AD date, compiled from the official BS calendar published annually. This is the only accurate way to convert dates between the two systems because:

This converter uses a verified BS calendar data table to give you exact, accurate results for any date within the supported range — not approximate calculations.

The Difference Between BS (Bikram Sambat) and AD (Gregorian)

The Bikram Sambat calendar and the Gregorian calendar are two entirely separate calendar systems with different starting points, different year lengths in days, and different month structures. Here is how they compare:

Feature BS (Bikram Sambat) AD (Gregorian)
Full name Bikram Sambat (also called Vikram Samvat) Anno Domini / Common Era (CE)
Used in Nepal (official), India (some states) Worldwide — international standard
Current year (2026 AD) 2082 / 2083 BS 2026
Year difference Approximately 56–57 years ahead of AD —
New Year Baisakh 1 (mid-April) January 1
Number of months 12 12
Days per month Varies — 29 to 32 days, changes every year Fixed — 28 to 31 days
Leap year equivalent Some months get extra days in certain years February gets 29 days every 4 years
Basis Lunisolar — based on both sun and moon cycles Solar — based on Earth’s orbit around the sun
Fiscal year (Nepal) Shrawan 1 to Ashadh end Mid-July to mid-July

Why is BS 56–57 Years Ahead of AD?

The Bikram Sambat calendar begins from 57 BCE — specifically commemorating the legendary king Vikramaditya of Ujjain. The calendar was established approximately 57 years before the Christian Era (Anno Domini) began. This is why when you convert any AD year to BS, you add approximately 56 or 57 — the exact number depends on whether the date falls before or after Baisakh 1 (mid-April) in any given year.

This is why 2026 AD spans two BS years — 2082 BS (until around mid-April 2026) and 2083 BS (from around mid-April 2026 onwards).

Common Uses of the Nepali Date Converter

All official Nepali government documents — citizenship cards, birth certificates, property deeds, court documents, and official letters — use BS dates. When dealing with these documents internationally or translating them for foreign use, AD to BS and BS to AD conversion is essential. Citizenship cards issued in Nepal show date of birth in BS — you need BS to AD conversion for passport applications, visa forms, and foreign bank accounts.

Academic Records

School leaving certificates (SLC / SEE), plus two certificates, and university transcripts from Nepali institutions typically carry BS dates. When applying to universities abroad or submitting academic credentials to foreign employers, you need the AD equivalent of those dates.

Finance and Banking

Nepal’s fiscal year runs from Shrawan 1 to Ashadh end (mid-July to mid-July) in the BS calendar. Tax filings, audit reports, financial statements, and IRD documents all use BS dates. For international businesses operating in Nepal or Nepali businesses dealing with foreign partners, date conversion is a regular administrative task.

Festivals and Events

Major Nepali festivals — Dashain, Tihar, Teej, Chhath, Maghe Sankranti, and others — fall on specific BS dates that change in AD each year. The BS to AD converter helps you find out the exact English calendar date for any Nepali festival in any given year.

Historical Research

Historical Nepali records, royal proclamations, and old property documents are written in BS dates that can span back centuries. Researchers and historians need to convert these to AD for cross-referencing with international historical records.

NRN and Diaspora Use

Nepalis living abroad frequently need to convert dates — for renewing Nepali documents like passports and citizenship, for sending remittances that require passport date verification, for communicating with family about festival dates, and for maintaining bilingual records for personal or business use.

Nepali New Year — Baisakh 1 in AD

The Nepali New Year falls on Baisakh 1 of each BS year — which corresponds to approximately April 13 or 14 in the AD calendar, depending on the year. It is not always the same AD date — it shifts slightly year to year:

BS Year Baisakh 1 in AD
2080 BS April 14, 2023
2081 BS April 13, 2024
2082 BS April 14, 2025
2083 BS April 14, 2026
2084 BS April 14, 2027 (approx)

Use the converter above to find the exact AD equivalent of any Baisakh 1 or any other Nepali festival date for any year.

Nepali Fiscal Year Dates — BS and AD

Nepal’s fiscal year runs from Shrawan 1 to Ashadh end. Here are the recent fiscal years with their exact AD dates:

BS Fiscal Year Start (AD) End (AD)
2080/81 July 17, 2023 July 15, 2024
2081/82 July 16, 2024 July 15, 2025
2082/83 (current) July 16, 2025 July 15, 2026
2083/84 (upcoming) July 16, 2026 July 15, 2027 (approx)

Frequently Asked Questions

What is the difference between AD and BS calendar?

AD (Anno Domini) is the Gregorian calendar used internationally — it starts from January 1 and is based on the solar year. BS (Bikram Sambat) is Nepal’s official calendar — it starts from Baisakh 1 (mid-April) and is currently about 56–57 years ahead of AD. The BS calendar is lunisolar, meaning its months are based on both the sun and the moon, which is why BS months have variable numbers of days (29 to 32) that change from year to year.

How do I convert AD to BS manually?

For an approximate conversion, add 56 to the AD year if the date falls between January and mid-April, or add 57 if the date falls between mid-April and December. For example, January 15, 2026 is approximately in 2082 BS, while June 1, 2026 is approximately in 2083 BS. However, this only gives the approximate year. For the exact day and month, you need a conversion tool like the one above because BS months have variable days that change every year.

What year is it in Nepal right now?

Nepal is currently in BS year 2083 (as of June 2026 AD). The Nepali New Year 2083 began on Baisakh 1, 2083 — April 14, 2026 AD. The current date in Nepal is Jestha 18, 2083 BS.

Why is the Nepali calendar different from the English calendar?

The Nepali Bikram Sambat calendar has a different origin point than the Gregorian calendar. BS begins from 57 BCE — it was established roughly 57 years before the Christian Era. Additionally, BS is a lunisolar calendar (based on both sun and moon cycles) while the Gregorian calendar is purely solar. This gives them different month lengths, different starting points in the year, and a year difference of 56–57 years.

What are the Nepali months in English?

The 12 Nepali months in order are: Baisakh (1), Jestha (2), Ashadh (3), Shrawan (4), Bhadra (5), Ashwin (6), Kartik (7), Mangsir (8), Poush (9), Magh (10), Falgun (11), and Chaitra (12). The year starts with Baisakh in mid-April and ends with Chaitra in mid-April of the following year.

How many days does a Nepali month have?

Unlike the Gregorian calendar where each month has a fixed number of days, Nepali BS months have variable days — ranging from 29 to 32 days. The exact number of days in each month changes every year and is determined by the official BS calendar published annually. This is why a simple formula cannot give you the exact day when converting between BS and AD — you need a data-table-based converter.

What is today’s date in Nepali BS calendar?

Today, June 1, 2026 AD corresponds to Jestha 18, 2083 BS. The converter above always reflects the current date. You can also use the BS to AD tab to look up any specific BS date and find its AD equivalent.

Can I use this converter for dates from the past or future?

Yes. The converter supports historical and future dates within the range of the BS calendar data table it uses. Most online BS-AD converters support dates from approximately 1975 BS (1918 AD) to 2100 BS (2043 AD). If you need to convert very old historical dates, the converter may not have data for those years — in that case, a specialist historical calendar resource is needed.

Is Bikram Sambat only used in Nepal?

Bikram Sambat is the official calendar of Nepal and is used across all government, legal, and official contexts. A version of the Vikram Samvat calendar is also used in some Indian states for religious purposes, but the specific BS calendar used in Nepal has its own regional variations and is distinct from the Indian Vikram Samvat in some month lengths and details.

What is the BS equivalent of January 1, 2026?

January 1, 2026 AD corresponds to Poush 17, 2082 BS. Use the converter above to find the BS equivalent of any AD date.

How do I convert my date of birth from BS to AD for a visa application?

Use the BS to AD tab in the converter above. Select your BS birth year from the dropdown, select your BS birth month by name (for example, if your citizenship card says Baisakh, select Baisakh), enter your BS birth day, and click Convert. The exact AD date will appear — this is the date you should enter on your visa application, passport form, or any international document that requires an AD date of birth.
