उमेर क्याल्कुलेटर — About This Age Calculator
यो निःशुल्क उमेर क्याल्कुलेटर ले तपाईंको उमेर वर्ष, महिना र दिनमा गणना गर्छ। तपाईंले अंग्रेजी (AD) वा नेपाली विक्रम संवत् (BS) मितिमा जन्म मिति र "as of" मिति भर्न सक्नुहुन्छ। BS मितिको हकमा क्याल्कुलेटरले आन्तरिक रूपमा AD मा परिवर्तन गरी दुई मितिबीचको फरक गणना गर्छ।
Use this free online age calculator to find your age in years, months and days. You can enter dates in the Gregorian AD calendar or in Nepal's commonly used BS (Bikram Sambat) calendar. For BS input, the calculator converts the date to AD internally before calculating the difference between the birth date and the selected “as of” date.
Because Bikram Sambat months vary from 29 to 32 days — unlike the fixed 28–31 days of the Gregorian calendar — an accurate age calculator must use year-specific BS month data. This tool uses the same conversion engine as our BS ↔ AD date converter, ensuring the results match official Nepali records.

ई.सं. र बि.सं. उमेर गणना — AD vs BS Age Calculation
AD refers to the Gregorian calendar, used in most of the world. BS refers to Bikram Sambat — the lunisolar calendar used widely in Nepal for official documents, school admissions, government forms and everyday life.
Because the two calendars don't align exactly (BS runs roughly 56.7 years ahead of AD), a simple year subtraction gives the wrong age. This calculator converts both BS dates to their exact Gregorian equivalents, then computes the difference — so the answer is precise to the day.
