Why do I need to convert between these calendars?

You might need to convert dates when dealing with official documents in Nepal (which use BS), international documents (which use AD), or when planning events that involve people using different calendar systems. Many Nepali citizens need to provide both BS and AD dates for various official purposes.

How accurate is the conversion?

Our converter is highly accurate for dates between 1944-2033 AD (2000-2090 BS). The conversion accounts for all variations in the Nepali calendar including leap years and varying month lengths. However, very old historical dates (before 1944) may have slight variations due to calendar reforms.

Does the converter work on mobile devices?

Yes, our converter is fully responsive and works perfectly on smartphones and tablets. You can use it on any device with a modern web browser.

Why are some dates not available for conversion?

The converter supports dates between 1944-2033 AD (2000-2090 BS). Dates outside this range are not supported because the Nepali calendar data for those years is not standardized in our database. We may expand the range in future updates.

Is my data secure when using this converter?

Absolutely. All conversion happens locally in your browser - your dates are never sent to our servers or stored anywhere. This ensures complete privacy and security for your information.

About Nepali Date Converter

The Nepali Date Converter is an essential utility for individuals, businesses, and organizations working with dates in Nepal. Nepal uniquely uses the Bikram Sambat (BS) calendar as its official standard for government, finance, and civil events. In contrast, international communication and digital platforms run on the Gregorian calendar (Anno Domini - AD).

Our converter bridges this calendar gap, facilitating seamless translations of birth certificates, official contracts, tax documents, academic certificates, and historical recordings.

The Bikram Sambat (BS) Calendar System

Established by King Vikramaditya, the Bikram Sambat calendar is approximately 56 years and 8.5 months ahead of the Gregorian calendar. The Nepali new year begins in mid-April (first day of Baishakh). Because BS is a lunisolar calendar, the number of days in each month changes dynamically from year to year (ranging from 29 to 32 days). This variability makes manual calculation extremely difficult and underscores the necessity of a reliable automated converter.

Frequently Asked Questions

What is the difference between Bikram Sambat and Gregorian calendars?

Bikram Sambat (BS) is the official civil calendar of Nepal, approximately 56.7 years ahead of the internationally used Gregorian calendar (AD). BS is a lunisolar system, whereas AD is purely solar. The Nepali year commences mid-April with the month of Baishakh.

Why do Nepali months have varying days every year?

Unlike the fixed month lengths of the Gregorian calendar, Bikram Sambat month lengths are determined by the astrological transit of the sun across different zodiac signs. Consequently, months like Baishakh can have 30 days one year and 31 or 32 days the next. Our converter uses hardcoded astrological tables to guarantee 100% accuracy.

How accurate is this converter for official work?

Our database covers years from 2000 BS to 2090 BS (1944 AD to 2033 AD). The conversion logic complies precisely with Nepali government guidelines and is 100% accurate and reliable for all official administrative, academic, and financial documents.
