There’s always that one moment — you’re filling out a form, applying for a passport, registering at a bank, or submitting a job application — and the field says “Date of Birth (BS).” Or sometimes the opposite: a foreign university asks for your DOB in AD, but you only know your Nepali date. If you’ve been there, you know the mild panic of doing the math in your head and wondering whether you got it right.
That’s exactly what this Date Converter is built for.
Our free Nepali Date Converter lets you switch between Bikram Sambat (BS) and the Gregorian (AD) calendar in seconds — no mental math, no looking up tables, no guessing. Select your date, hit Convert, and you have the accurate result along with the day of the week and full date details.

About Nepali Date Converter
The Bikram Sambat (BS) calendar is the official calendar of Nepal. It is approximately 56 years and 8 months ahead of the Gregorian (AD) calendar. Unlike the Gregorian calendar, BS months have varying lengths (29-32 days) that change from year to year, making manual conversion difficult.
How the Conversion Works
This converter uses an authoritative lookup table of days per month for each BS year from 2000 to 2090. It counts the total days between a reference date (BS 2000/01/01 = AD 1943/04/14) and your selected date, then maps it to the target calendar system accurately.
What Is a Date Converter?
A Date Converter is a tool that translates dates from one calendar system to another. In Nepal’s context, this almost always means converting between Bikram Sambat (BS) — the official Nepali calendar — and the Gregorian calendar (AD) that the rest of the world uses.
The tool works in both directions:
- BS → AD (Nepali to English date): Enter a Nepali date in Bikram Sambat and get the corresponding English date.
- AD → BS (English to Nepali date): Enter an English date in Gregorian format and get the Nepali date in BS.
Understanding the Two Calendars
Bikram Sambat (BS) — Nepal’s Official Calendar
Bikram Sambat is Nepal’s national calendar. Every official document in the country — citizenship certificates, land registration papers, court records, tax filings — uses BS dates. Schools follow the BS academic year. Public holidays, festivals like Dashain and Tihar, and government notifications are all published in BS.
The calendar is named after Emperor Vikramaditya and is believed to have been established around 56–57 BCE. It runs approximately 56 years and 8 months ahead of the Gregorian calendar. So right now, as AD 2026 is in progress, Nepal is in BS 2082–2083.
What makes BS genuinely tricky is its month lengths. Unlike the Gregorian calendar, where you can memorize “30 days hath September” and be done with it, BS month lengths vary every single year. Baisakh might have 31 days one year and 32 days the next. Mangsir might be 29 days in one year and 30 in another. These variations follow solar and astronomical cycles, and they change across the decades. There’s no shortcut formula — you need a lookup table for each year.
That’s why manual conversion is genuinely error-prone, and why an accurate date converter is so useful.
Gregorian Calendar (AD) — The International Standard
The Gregorian calendar — also called the Christian Era (CE) or Anno Domini (AD) — is the civil calendar used worldwide. Introduced in 1582, it’s a solar calendar with fixed month lengths and a leap year every four years (with some exceptions for century years). When you’re dealing with visa applications, foreign university admissions, international banking, or any document meant for use outside Nepal, you’ll be working in AD.
The Starting Point: BS 2000/01/01 = AD 1943/04/14
Our converter uses a verified reference date — the first day of BS 2000 corresponds to April 14, 1943 in the Gregorian calendar. From that anchor, it counts the exact number of days forward or backward using a complete lookup table of BS month lengths from 2000 to 2090. This is how accurate conversion works — not by formula alone, but by matching day counts against authoritative data.
How to Use the Date Converter on calculatornp.com
The converter is designed to be straightforward. Here’s how to use it:
BS to AD Conversion (Nepali to English Date)
- Select the BS → AD tab at the top of the converter.
- Choose your Nepali year (BS) from the dropdown — ranging from 2000 to 2090.
- Select the Nepali month (Baisakh through Chaitra).
- Enter the day.
- Click Convert.
The result will show you:
- The corresponding English date (AD)
- The day of the week for that date
- The number of days in that BS month (useful for cross-checking)
AD to BS Conversion (English to Nepali Date)
- Select the AD → BS tab.
- Choose your English year (AD) from the dropdown.
- Select the English month (January through December).
- Enter the day.
- Click Convert.
You’ll get the Nepali date in BS along with the day of the week and full date details.
There’s also a Today’s Date button that instantly loads today’s date in both BS and AD — handy when you just want to know what the current Nepali date is without typing anything.
When Do You Actually Need a Date Converter?
More often than most people think. Here are the most common situations where Nepalis need to convert dates:
1. Date of Birth for Official Documents
This is the single most common use. Most Nepalis born before the digital era know their date of birth only in BS — it’s written that way on their citizenship card. When applying for a passport, DV Lottery, foreign university, or any international form, the birthdate field expects AD. Getting this wrong, even by a single day, can cause problems with identity verification later.
2. Passport and Visa Applications
Nepal’s Department of Passport issues passports with the date of birth in AD. But citizenship cards and birth certificates are in BS. Converting accurately is essential — the dates across documents need to match.
3. DV Lottery (Diversity Visa Program)
Thousands of Nepalis apply for the US DV Lottery every year. The form requires date of birth in AD (MM/DD/YYYY format). An incorrect date here could disqualify an application or create issues if selected.
4. Lok Sewa Aayog and Government Job Applications
Public Service Commission forms in Nepal ask for dates in BS. If you’ve been working in a private organization that maintains records in AD, you’ll need to convert your experience dates and DOB into BS format.
5. Bank Account Opening and KYC
Many Nepali banks use BS for internal records. When opening accounts or completing KYC, you’ll be asked for your BS date of birth even if your identity documents show AD. The converter helps you go in the right direction quickly.
6. Property and Land Records (Lalpurja)
Land registration and lalpurja documents in Nepal use BS exclusively. If you’re buying or selling property and need to reference historical dates on title deeds, you might need to convert between BS and AD for legal or tax purposes.
7. Academic Records and Transcripts
Schools and colleges in Nepal issue transcripts with dates in BS. When applying abroad for higher studies, your SOP, application forms, and unofficial records need to show AD dates. Transcript apostille processes also sometimes require both formats.
8. Historical Date Research
Journalists, historians, genealogists, or anyone researching Nepali events from the past often work with BS dates in source material and need to place those events in an international timeline.
The 12 Months of Bikram Sambat
For those less familiar, the Nepali calendar months in order are:
- Baisakh (बैशाख) — April/May
- Jestha (जेठ) — May/June
- Ashadh (असार) — June/July
- Shrawan (साउन) — July/August
- Bhadra (भदौ) — August/September
- Ashwin (असोज) — September/October
- Kartik (कार्तिक) — October/November
- Mangsir (मंसिर) — November/December
- Poush (पुस) — December/January
- Magh (माघ) — January/February
- Falgun (फागुन) — February/March
- Chaitra (चैत) — March/April
Nepali New Year (Naya Barsha) falls on Baisakh 1, which is typically April 13 or 14 in the Gregorian calendar.
Common Date Conversion Questions
What year is BS 2082 in AD?
BS 2082 spans two Gregorian years. From Baisakh 1, 2082 (approximately April 14, 2025) through Chaitra 30, 2082 (approximately April 13, 2026). So most of AD 2025 and the first few months of AD 2026 correspond to BS 2082.
What year is BS 2083 in AD?
BS 2083 begins around April 14, 2026 (Baisakh 1, 2083 — Nepali New Year 2083) and runs through approximately April 13, 2027. So most of AD 2026 falls within BS 2082–2083.
How many days ahead is BS from AD?
Bikram Sambat is approximately 56 years and 8 months ahead of the Gregorian calendar. This is why 1943 AD corresponds to 2000 BS, and 2026 AD corresponds to 2082–2083 BS.
Why do BS months have irregular day counts?
Because the Bikram Sambat calendar is a lunisolar system — it accounts for both the solar year and lunar cycles. Month lengths are recalculated based on astronomical data for each year, which is why Baisakh might be 31 days in one year and 32 in another. This is what makes manual calculation unreliable and a lookup-based converter essential.
Is there a difference between Bikram Sambat and Vikram Samvat?
They’re the same calendar. “Bikram Sambat” is the Nepali pronunciation, while “Vikram Samvat” is the Sanskrit/Hindi rendering. In Nepal, the BS calendar is specifically adapted with month-length tables determined by the government, so there can be minor differences from the Indian Vikram Samvat used in some Indian states.
Why Use calculatornp.com’s Date Converter?
There are other Nepali date converters online. What makes ours reliable:
Accurate lookup table: The converter uses verified BS month-length data from 2000 BS to 2090 BS — the same authoritative data used in government and academic contexts. It counts actual days from a confirmed reference point rather than estimating.
Both directions, one tool: Switch between BS → AD and AD → BS in the same interface with a single click. No separate pages, no reloading.
Day of week and extra details: Along with the converted date, you also see the day of the week and the number of days in that particular BS month — details that are genuinely useful when you’re working with time-sensitive documents.
Today’s date shortcut: One click loads the current date in both calendars. Useful when you just want to know today’s Nepali date without typing anything in.
No login, no installation: Open the page, use the converter, get the result. That’s it.
Tips for Using the Date Converter Accurately
A few things worth keeping in mind when converting dates:
Always double-check date-of-birth conversions. For documents like passports, visas, and DV Lottery forms, the DOB needs to be exactly right. Use the converter, note the result, and verify it matches your citizenship card or birth certificate.
Be aware of the BS year boundary. Nepali New Year falls around April 13–14 in AD. If your date is near that time of year, double-check which BS year you’re in — it’s easy to be off by one year around the new year transition.
For dates before 2000 BS: Our converter covers 2000 BS to 2090 BS (AD 1943 to 2034). If you need to convert historical dates before this range, you may need a specialized historical converter.
Document translation use: If you’re translating a Nepali document for official use abroad, include both the original BS date and the converted AD date for clarity. Many translation firms and embassies expect both.
Final Thought
The Bikram Sambat calendar is deeply woven into Nepali life — from daily newspapers to land records to the way Dashain and Tihar are scheduled every year. But when Nepal connects with the world, the Gregorian calendar is the common language. Our Nepali Date Converter sits at that junction and makes the crossing simple.
Whether you’re converting your date of birth for a DV Lottery entry, checking a property document date, or helping a family member fill out a foreign university application — this tool handles it accurately, instantly, and without any fuss.
Use it whenever you need it. It’s free.

Frequently Asked Questions
What is a Nepali date converter? A Nepali date converter is an online tool that converts dates between the Bikram Sambat (BS) Nepali calendar and the Gregorian (AD) calendar. It works in both directions — BS to AD and AD to BS — and is used for government forms, passports, bank accounts, DV Lottery, and academic records.
How do I convert my Nepali date of birth to English? Select the BS → AD tab on the converter, enter your birth year in BS, choose the Nepali month, enter the day, and click Convert. The tool will instantly display your date of birth in the English (AD) format with the correct day of the week.
How many years ahead is Nepali BS calendar from AD? Bikram Sambat is approximately 56 years and 8 months ahead of the Gregorian calendar. For example, BS 2082 corresponds to AD 2025–2026, and BS 2083 begins on approximately April 14, 2026.
Is this converter accurate for DV Lottery applications? Yes. Our converter uses a verified day-count method based on authoritative BS month-length data from 2000 to 2090 BS. Always cross-check the converted date against your original citizenship document or birth certificate before submitting any official form.
What is the difference between BS and AD calendar month lengths? Gregorian (AD) months have fixed lengths — 28 to 31 days, consistent every year (with leap year exception). Bikram Sambat (BS) months vary year to year, ranging from 29 to 32 days based on astronomical calculations. This variability is why manual conversion is unreliable and a lookup-based tool is necessary.
Can I convert today’s date from AD to BS? Yes. Click the “Today’s Date” button on the converter and it will automatically show you today’s date in both BS and AD formats, along with the day of the week.
What does मिति परिवर्तन (Miti Pariwartan) mean? मिति परिवर्तन (Miti Pariwartan) is the Nepali term for “date conversion” — literally, “changing the date.” It refers to converting a date from Bikram Sambat to Gregorian or vice versa, which is one of the most common everyday tasks for Nepalis dealing with official paperwork.
