Citizenship and loksewa forms often ask for date of birth in both BS and AD. A common trap: if your birth falls in Baisakh 1-13 range, double-check whether the AD year should be the current year or the previous one. The Nepali New Year (Baisakh 1) falls around April 13-14, so dates before that cutoff belong to the previous AD year.
Check exact days, AD start/end date, and weekday for any Nepali month.
Calculate days between two AD dates and see both dates in BS too.
BS runs 56–57 years ahead of AD. Nepal's New Year (Baisakh 1) falls mid-April each year.
BS months range 29–32 days. Every year has a unique set of month lengths, unlike fixed Gregorian months.
Uses a fixed BS month-length dataset from BS 2000 to 2090 and the base reference BS 2000/1/1 = AD 1943/4/14.
Use this table to quickly find which AD year a given BS year corresponds to, and when each Nepali New Year (Baisakh 1) falls in AD.
| BS Year | Devanagari | AD Start (Baisakh 1) | AD End (Chaitra end) | Baisakh 1 in AD |
|---|---|---|---|---|
| BS 2078 | २०७८ | April 13, 2021 | April 12, 2022 | April 13, 2021 |
| BS 2079 | २०७९ | April 13, 2022 | April 13, 2023 | April 13, 2022 |
| BS 2080 | २०८० | April 14, 2023 | April 12, 2024 | April 14, 2023 |

The Bikram Sambat (BS) calendar, also called Vikram Samvat or simply the Nepali calendar, is the official national calendar of Nepal. Named after the legendary Hindu king Vikramaditya, it runs approximately 56 years and 8.5 months ahead of the Gregorian (AD) calendar used internationally.
Every official document in Nepal, from land registration (Lalpurja) and birth certificates to government notices and Lok Sewa Aayog results, uses Bikram Sambat dates. Understanding how to convert BS to AD and AD to BS is essential for Nepalis living abroad, NRNs handling official documents, and anyone dealing with Nepal's administrative system. If you need the current Nepali date before converting, see our guide to today's Nepali date.
In Nepal, मिति परिवर्तन (miti pariwartan), meaning date conversion, is a routine task. Whether you need your birth date in AD for a foreign visa application, or need to convert an AD deadline to BS for a government form, this converter handles both directions instantly. For a fuller explanation of date systems and common use cases, you can also read our BS to AD date conversion guide.
The conversion algorithm is based on a fixed reference point: BS 2000 Baisakh 1 = AD 1943 April 14. From this base, the number of days elapsed in the BS calendar is calculated using a dataset of exact month lengths for each year from BS 2000 to 2090. These month lengths vary every year, which is a key difference from the Gregorian calendar where months have fixed lengths.
This tool uses a fixed BS month-length dataset covering BS 2000–2090. Every conversion is calculated from the base reference BS 2000/1/1 = AD 1943/4/14, so the converter, detail rows, reference table, and FAQ examples all use the same source data.
| # | BS Month | Devanagari | AD Equivalent (approx.) | Days |
|---|---|---|---|---|
| 1 | Baisakh | बैशाख | mid April – mid May | 30–32 |
| 2 | Jestha | जेठ | mid May – mid June | 31–32 |
| 3 | Ashadh | असार | mid June – mid July | 31–32 |
| 4 | Shrawan | श्रावण | mid July – mid August | 31–32 |
| 5 | Bhadra | भदौ | mid August – mid September | 29–32 |
| 6 | Ashwin | आश्विन | mid September – mid October | 29–30 |
| 7 | Kartik | कार्तिक | mid October – mid November | 29–30 |
| 8 | Mangsir | मंसिर | mid November – mid December | 29–30 |
| 9 | Poush | पौष | mid December – mid January | 29–30 |
| 10 | Magh | माघ | mid January – mid February | 29–30 |
| 11 | Falgun | फाल्गुन | mid February – mid March | 29–30 |
| 12 | Chaitra | चैत्र | mid March – mid April | 30–31 |
The Nepali New Year begins on Baisakh 1, which falls on April 13 or 14 in the Gregorian calendar. The last month, Chaitra, typically ends around April 12–13 the following year.
| Feature | Bikram Sambat (BS) | Gregorian (AD) |
|---|---|---|
| Year offset | ~56–57 years ahead of AD | Base reference |
| New Year | Baisakh 1 (mid-April) | January 1 |
| Month lengths | 29–32 days, varies each year | 28–31 days, mostly fixed |
| Total months | 12 (no leap month) | 12 (+ leap day in Feb) |
| Official use | Nepal government, legal docs | International standard |
| Calendar basis | Lunisolar (adjusted) | Solar |
In Nepal, dates in official documents are written as Year/Month/Day in BS. For example, BS 2082/04/15 means year 2082, 4th month (Shrawan), 15th day. In Devanagari, this would be written as २०८२/०४/१५.
When filling in government forms or Lok Sewa applications, you will typically see a format like YYYY-MM-DD in BS. Make sure to use the BS date, not the AD date, unless the form specifically asks for AD (English) date.
As a quick rule: subtract 56 or 57 from any BS year to get the approximate AD year. The exact offset depends on the time of year (before or after mid-April when Baisakh 1 falls).
For precise conversion on any specific date, always use the converter above. If you are checking festival timing or year transitions, our Dashain and Tihar 2083 guide is another useful reference.
One small date mistake can create a surprisingly big headache in Nepal. A student fills an abroad study form and writes the AD birth year one year ahead. A Lok Sewa candidate copies the BS date from citizenship but forgets to convert the application deadline to AD for reminder. A family checking Lalpurja papers sees a registration date in BS and argues about which English year the land was bought.
This is why a Nepali date converter is not only a calendar tool. It is a daily paperwork helper. It saves you from guessing, especially around Baisakh when BS and AD years feel confusing. In normal conversation, people say “2082 chalirako cha” and “2026 ho” in the same sentence. In official documents, that casual mixing can become a problem.
The safest habit is simple. Convert the date, copy the output, and keep both BS and AD versions in the same note. If you are filling a form, write exactly what the form asks. If it says BS, do not enter AD. If it says AD, do not enter BS. If it asks both, use the same source date and convert once, not from memory.
If the date is for citizenship, passport, Lok Sewa, land records, bank KYC, school certificate, visa form or tax filing, never use the rough “minus 56 or 57” rule as the final answer. Use the converter and check the weekday or month detail if the document is important.
The most common confusion happens around mid-April. Nepal’s New Year starts on Baisakh 1, usually around April 13 or 14. So January, February, March and early April of an AD year usually belong to the previous BS year. After Baisakh 1, the new BS year begins.
For example, AD 2026 contains part of BS 2082 and part of BS 2083. Someone born in February 2026 is not born in BS 2083. That date still falls in BS 2082. But someone born after Baisakh 1 in April 2026 falls in BS 2083. This is where people make mistakes while filling DOB in school, passport and embassy forms.
In a Kathmandu cyber near Bagbazar or Putalisadak, the operator may know this from habit. But if you are filling the form yourself on a phone at midnight, the year shift is easy to miss. This tool removes that guesswork.
| Situation | Common Wrong Guess | Better Way | Why It Matters |
|---|---|---|---|
| Birth date before mid-April | Subtract only 56 years | Use exact converter | AD year may be one year earlier than expected |
| Lok Sewa deadline in BS | Set phone reminder by rough month | Convert BS deadline to AD and set reminder | Missing deadline by one day can reject application |
| Lalpurja registration date | Estimate from BS year only | Convert exact BS year, month and day | Land history and loan documents need exact date |
| Bank KYC date of birth | Copy from memory | Match citizenship BS date and converted AD date | Mismatch can delay account opening or remittance work |
| Visa or university form | Use Nepali date in AD field | Convert to AD format first | Foreign systems usually require Gregorian dates |
Lok Sewa candidates live between two calendars. Vacancy notices, exam dates, result notices and age eligibility are usually written in BS. But phone calendar reminders, email alerts, Google Calendar and travel planning are easier in AD. If your exam centre is in Kathmandu, Pokhara, Butwal, Surkhet or Dhangadhi, you may also need to book travel based on AD dates.
Many candidates do one risky thing. They see a BS deadline and mentally convert the month. Then they plan to apply “next week”. This is dangerous because BS month lengths change. Some months have 29 days, some have 30, some have 31 and some can have 32 depending on the year. A mental estimate is okay for conversation, not for an application deadline.
Use this pattern: convert the BS deadline to AD, set two reminders, one three days before and one one day before. If the form needs a birth date in both calendars, convert your date of birth once and save it in a note named “DOB BS AD”. That tiny note can save you every time you fill an online form.
Convert the published BS deadline to AD.
Check the weekday so you know whether it falls on office day or weekend.
Set reminders in your phone using the AD date.
Submit early instead of waiting for the final day.
If you are applying for a passport, foreign university, work visa, WES or ECE evaluation, you will often need AD dates. Your Nepali citizenship, school record or old certificate may show the date in BS. This is where exact conversion becomes important.
Foreign forms usually expect dates in Gregorian format, often YYYY-MM-DD or DD/MM/YYYY. A Nepali date written directly into that field can create mismatch. For example, 2082/05/20 is normal in Nepal, but in an international form it is invalid because AD year 2082 is far in the future.
When converting for foreign paperwork, copy the converted AD date and then match the format required by the form. If the form says month first, be careful. 05/06/2026 can mean May 6 or June 5 depending on the country. The copy-ready formats on this page help reduce that confusion.
| Form Type | Often Needed Date | Safer Format | Practical Tip |
|---|---|---|---|
| Nepali citizenship | BS date of birth | YYYY/MM/DD in BS | Keep the original as written on citizenship |
| Passport application | BS and AD date of birth | Both BS and AD | Use the same source date for conversion |
| Embassy or visa form | AD date | YYYY-MM-DD if accepted | Avoid ambiguous 05/06 style dates |
| University application | AD birth date and certificate dates | Full month name or ISO style | Match the date with your documents |
| Bank KYC abroad | AD date from Nepali ID | Copy-ready AD format | Save converted date for future reuse |
Some date conversions are casual. Some are sensitive. Converting a birthday for a Facebook post is low risk. Converting a birth date for passport, age eligibility or land document is high risk. The chart below is not a technical score. It is a practical risk guide based on how painful a wrong date can become in real Nepali paperwork.
For Nepalis living abroad, date conversion becomes a family support task. Parents in Nepal may send a citizenship photo on WhatsApp. The son or daughter in Australia, Qatar, Japan, Korea, the UK or the US then has to fill an online form in AD. If the converted date is wrong, the correction process can be slow.
A good family habit is to keep a shared note with important dates in both formats. Add the person’s name, original BS date, converted AD date, and source document. For example: “Father DOB: BS 2028/09/12, AD converted date, source: citizenship.” This is boring work for ten minutes, but it becomes very useful during passport renewal, insurance, banking, medical appointments and travel booking.
Do not rely only on screenshots. Screenshots get buried in chats. A simple text note is easier to search later. If the date is for a legal document, keep the original scan too.
Many people assume Nepali months work like English months with fixed lengths. They do not. Baisakh, Jestha, Ashadh and Shrawan are often longer, while some later months are shorter. But the exact length can vary by year. That is why “same month same day” does not always land on the same AD date each year.
This matters for recurring reminders. A wedding anniversary in BS will not always fall on the same AD date. A birthday celebrated by BS date will move in the English calendar. A loan installment or rent agreement written in BS should be checked carefully if you are also tracking it in Google Calendar.
| BS Month Group | Practical Pattern | Common Use | Reminder Tip |
|---|---|---|---|
| Baisakh to Shrawan | Often longer months | New year, school cycle, fiscal planning | Convert exact date before setting AD reminder |
| Bhadra to Mangsir | Festival and wedding-heavy period | Teej, Dashain, Tihar, weddings | Check weekday for travel and office closure planning |
| Poush to Falgun | Winter documents and renewal period | Banking, school forms, tax and office work | Keep both BS and AD copy-ready formats |
| Chaitra | Year-end transition | Fiscal preparation, new year planning | Be careful around Baisakh year change |
Land and tax documents in Nepal are date-sensitive. Lalpurja records, rajinama dates, bank loan papers, ward recommendations, rental agreements, PAN and VAT documents, and company registration files can all involve BS dates. When these documents are used for banks, embassies, auditors or foreign partners, AD conversion may be needed.
The local problem is that different offices may ask for different formats. One office may say “2082-05-12”. Another may prefer “2082/05/12”. A foreign email may need “August 28, 2025”. This page gives copy-ready formats so you do not have to rewrite the date manually each time.
If you are dealing with land papers, check the date slowly. Land documents already have many numbers: kitta number, ward number, area, amount, registration number and date. A date mistake can hide inside all that detail. Convert once, then compare the original paper again.
Before you submit a form, use this quick checklist. It is especially useful for government forms, passport applications, bank KYC, Lok Sewa forms, insurance papers and foreign education documents.
If you often fill forms, make one note on your phone called “Important BS AD Dates”. It is a small habit, but very useful. You do not need to convert the same date again and again. You also reduce the chance of typing a different answer each time.
For students, keep date of birth, SEE certificate date, transcript issued date and passport issued date. For working people, keep citizenship DOB, PAN registration date, passport issue date and employment start date. For business owners, keep company registration date, PAN or VAT registration date, lease start date and renewal dates.
| Person or Work | Dates to Save | Why Save Both BS and AD |
|---|---|---|
| Student | DOB, SEE date, transcript date | Useful for abroad study and scholarship forms |
| Job seeker | DOB, citizenship date, application deadlines | Useful for Lok Sewa and private job forms |
| NRN family | Parents' DOB, passport dates, citizenship dates | Useful for visa, insurance and remittance paperwork |
| Business owner | PAN, VAT, company registration, lease dates | Useful for tax, audit and banking |
| Land owner | Lalpurja, rajinama, loan and ward dates | Useful for bank valuation, sale and legal reference |
A Nepali date converter should feel boring in the best possible way. You enter a date, it gives the answer, and you move on with confidence. The danger starts when you try to be clever with rough year subtraction for important paperwork.
For casual planning, the mental rule is fine. For official work, use the converter. For family records, save both dates. For deadlines, set reminders. For Baisakh dates, check twice. That simple system is enough for most Nepali date problems in 2082/83 and beyond.
Today's Nepali date in BS is displayed live in the strip at the top of this page. As of mid-2026 AD, we are in BS 2083. The date updates automatically each time you open the page. You can also click the Today button in either tab to instantly load today's date into the converter.
Bikram Sambat (विक्रम संवत्) is Nepal's official calendar, running ~56 years and 8.5 months ahead of Gregorian AD. Unlike AD months which have fixed lengths, BS months range from 29–32 days and vary every year. All government, legal, and official documents in Nepal use BS dates.
Select the BS to AD tab, enter the Bikram Sambat year, choose the month from the dropdown, enter the day, then click Convert. The equivalent Gregorian date appears instantly with the day of week in both English and Nepali (Devanagari).
This tool uses a fixed BS month-length dataset for BS 2000–2090. It calculates from the base reference BS 2000/1/1 = AD 1943/4/14, and the same data is used by the converter, month inspector, details panel, and reference table.
AD 2026 spans BS 2082 (January to April 13, 2026) and BS 2083 (April 14, 2026 onwards). Each AD year spans two BS years because Nepal's New Year (Baisakh 1) falls around mid-April. Use the converter above to check any specific date.
In this converter dataset, BS 2083 Baisakh 1 falls on April 14, 2026 in the Gregorian calendar. Use the converter above to confirm: enter BS 2083, Month 1 (Baisakh), Day 1 and click Convert.
मिति परिवर्तन (miti pariwartan) is the Nepali term for date conversion, meaning changing a date from Bikram Sambat (BS) to Gregorian (AD) or vice versa. This is a common task in Nepal for anyone dealing with passports, banking, foreign education applications, government forms, or Lok Sewa Aayog paperwork.
The BS calendar does not have a defined leap year rule like the Gregorian calendar. Instead, each BS year has a unique pre-computed set of month lengths (29–32 days per month) based on astronomical calculations. Total days per BS year typically range from 365 to 366. After converting any date, click the Details panel to see the exact day count for that BS month.
Yes. This converter is accurate for Lok Sewa Aayog (PSC) deadlines, Lalpurja dates, citizenship documents, birth certificates, passport applications, bank records, and academic certificates. Always verify critical dates with official sources before submission.
