How to calculate your age
Calculating your age by hand means counting the full years from your date of birth to today, then the remaining months, then the leftover days - while accounting for months of different lengths and leap years. This online age calculator does it instantly and accurately:
- Choose your calendar - English (AD) or Nepali (Bikram Sambat / BS).
- Select your date of birth (year, month and day).
- Optionally change the second date to find your age on a past or future date instead of today.
- Press Calculate age to see your exact age in years, months and days.
A Nepali age calculator (umer) that understands BS dates
Many Nepalis know their date of birth in the Bikram Sambat calendar. Most age calculators only accept English dates, forcing you to convert first. This tool accepts a Nepali date of birth (BS) directly - it converts it to the Gregorian calendar behind the scenes using the official Nepali calendar data, then calculates your age. You can also calculate age from an English date of birth and see the matching Nepali date. Need only date conversion? Use our Nepali date converter.
