How is Age Calculated?
Age is calculated by finding the difference between your date of birth and today's date. A precise age calculator accounts for the varying number of days in each month and correctly handles leap years (years divisible by 4, except century years not divisible by 400). Simply counting years can give an inaccurate result — the exact breakdown in years, months and days gives a precise answer.

Frequently Asked Questions
How do you calculate age from date of birth?Subtract the birth year from the current year. Then check if the birth month/day has passed this year — if not, subtract one more year. For the exact months and days, calculate the month and day difference separately.
Does this calculator handle leap year birthdays (29 Feb)?Yes. For people born on 29 February, the calculator correctly computes age and considers 28 February or 1 March as the equivalent birthday in non-leap years depending on the convention used.
What is the maximum age this calculator supports?The calculator works for any date of birth. There is no upper limit — you can calculate the age of historical figures or fictional scenarios.
Can I calculate age in months only?Yes — total months lived = (years × 12) + remaining months. For total days lived, the calculator accounts for every month's actual length including February in leap years.
