Nepali Age Calculator
नेपाली उमेर क्याल्कुलेटर
Calculate exact age in years, months and days from a Bikram Sambat or English date, with the next birthday.
Find an exact age in years, months and days from a date of birth in Bikram Sambat or the English calendar. The tool also converts the date between the two calendars, shows the weekday, and counts the days to the next birthday.
About the Nepali age calculator
This calculator works out an exact age in years, months and days from a date of birth entered either in the Bikram Sambat (BS) calendar used in Nepal or the English (AD) calendar. It also converts the date of birth into the other calendar and shows the weekday, plus the date of the next birthday and how many days away it is. It is useful for filling official forms, school admissions, visa and passport paperwork, pensions and retirement planning, and simply settling the “how old am I?” question.
Counting age on the Nepali calendar
Bikram Sambat is the official calendar of Nepal. Its year runs about 56.7 years ahead of the Gregorian year, and its months (Baisakh through Chaitra) do not line up with the English months. Each BS month has 29 to 32 days, which changes slightly from year to year. Because of this, an age is best worked out by converting the Nepali dates to an exact day count rather than by subtracting the years and guessing.
How the calculation works
Both dates are converted to their Gregorian equivalents, then the elapsed time is broken down by anchoring on the birth date and advancing whole years and then whole months. This gives the precise years, months and days between the two dates, and handles end-of-month and leap-day (29 February) birthdays correctly. The same elapsed period is also reported as a total number of months, weeks and days.
Accuracy and range
The converter uses a verified day-by-day table covering 1975–2099 BS, which is roughly 1918 to 2043 in the English calendar, so every date in that window is exact rather than an approximation. Dates outside the range, or dates that do not exist (such as 29 February in a non-leap year), are flagged instead of being estimated.
