Check the Number of Days in a Nepali Year
Explore whether a Bikram Sambat (BS) year contains 365 or 366 days. Use the BS Leap Year Checker to check the selected Nepali calendar year and understand how its year length differs from the Gregorian calendar.
Check BS YearHave you ever wondered whether a Nepali calendar year is a leap year? The Leap Year Checker in BS helps you check the year length of a Bikram Sambat calendar year and understand whether it contains 365 or 366 days.
The Bikram Sambat calendar used in Nepal works differently from the Gregorian calendar commonly used internationally. Although a BS year can contain 365 or 366 days, it does not follow the familiar Gregorian leap-year rule based on February 29.
This online tool is useful for students, teachers, calendar researchers, office workers, and anyone who needs to understand the number of days in a Nepali calendar year.
What Is a Leap Year Checker in BS?
A Leap Year Checker in BS is a calendar utility designed to check the length of a selected Bikram Sambat year. Depending on the calendar data used, a year may contain 365 or 366 days.
In the Gregorian calendar, a leap year usually has 366 days because February includes an extra day. The Bikram Sambat calendar works differently: its individual months have varying lengths, and the total number of days in the year depends on the published calendar.
Therefore, checking a BS year requires calendar-specific information rather than applying the Gregorian leap-year formula.
How to Use the BS Leap Year Checker
Follow these steps to check a Bikram Sambat year:
Enter the Bikram Sambat year you want to check.
Click the checker button to process the selected year.
Read the result provided by the calendar checker.
Use the result to understand whether the selected BS year contains 365 or 366 days, according to the tool’s calendar data.
For important dates, verify the result against a reliable Nepali calendar for the selected year.
Does the Nepali Calendar Have Leap Years?
The answer depends on what you mean by a leap year.
In the Gregorian calendar, a leap year is a year with 366 days instead of 365. The extra day is added to February, and the leap-year rule follows a mathematical cycle based on divisibility by 4, 100, and 400.
Bikram Sambat does not use this same rule. Instead, Nepali calendar months have different lengths from year to year. The total number of days in a BS year may be 365 or 366.
BS Leap Year vs. Gregorian Leap Year
Although both calendar systems can have years with 366 days, their methods of determining calendar dates are different.
| Feature | Gregorian Calendar (AD) | Bikram Sambat Calendar (BS) |
|---|---|---|
| Year length | Usually 365 days; leap years have 366 | May contain 365 or 366 days |
| Leap-year rule | Uses a mathematical rule | Uses year-specific calendar data |
| Extra day | Added to February as February 29 | Month lengths vary according to the published BS calendar |
| Month lengths | Mostly fixed, with February changing in leap years | Can vary from 29 to 32 days |
| How to check | Apply Gregorian leap-year rule | Consult the BS calendar for the specific year |
Why Do BS Year Lengths Change?
The Bikram Sambat calendar follows a different calendar structure from the Gregorian calendar. The lengths of its months are determined according to the Nepali calendar system and published calendar information.
Unlike Gregorian months, which mostly have fixed lengths, BS months can contain 29, 30, 31, or 32 days. As a result, the total number of days in a BS year can differ from one year to another.
This is why a year-by-year calendar table is important for determining the exact number of days in a Nepali year.
How Many Days Are in a Nepali Year?
A Bikram Sambat year may have either 365 or 366 days. The exact total depends on the calendar for that particular year.
A BS year whose published calendar month lengths add up to 365 days.
A BS year whose published calendar month lengths add up to 366 days.
For example, published calendar data indicates that BS 2082 contains 365 days, while BS 2083 contains 366 days. These examples illustrate why BS year lengths should be checked individually rather than determined using a repeating formula.
BS Calendar Months and Their Variable Lengths
The Bikram Sambat calendar has 12 months. Their lengths are not permanently fixed across all years.
| Month | Nepali Name | Typical Length Range |
|---|---|---|
| Baisakh | वैशाख | 29–31 days |
| Jestha | जेठ | 29–32 days |
| Ashadh | असार | 29–32 days |
| Shrawan | साउन | 29–32 days |
| Bhadra | भदौ | 29–32 days |
| Ashwin | असोज | 29–32 days |
| Kartik | कार्तिक | 29–32 days |
| Mangsir | मंसिर | 29–32 days |
| Poush | पुष | 29–32 days |
| Magh | माघ | 29–32 days |
| Falgun | फागुन | 29–32 days |
| Chaitra | चैत | 29–32 days |
Note: The table shows the general possible range of BS month lengths, not the exact number of days in every month. For a specific year, consult that year’s calendar.
