How is Age Calculated?

Age is calculated by finding the difference between the date of birth and the current date (or any specified date). The calculation considers the exact number of years, months, and days elapsed.

Leap Year Consideration

Our age calculator correctly handles leap years. A leap year occurs every 4 years (with some exceptions), so people born on February 29 will have their birthday counted on February 28 in non-leap years.

Why Calculate Your Exact Age?

Exact age is required for many official purposes — government documents, passport applications, school admissions, insurance policies, and medical assessments. Our tool gives you the age to the day, not just the year.

Date of Birth Calculator — Age from Your DOB

This tool doubles as a date of birth calculator. Enter your DOB and it works out how much time has passed, down to the exact day. Simply subtracting birth years is not enough, because whether your birthday has already occurred this year changes the answer by a full year.

Example

Someone born on 15 December 1998, checked on 1 June 2026, is 27 years, 5 months and 17 days old — not 28, even though 2026 minus 1998 equals 28. The birthday has not arrived yet this year.

Birthday Calculator — Days Until Your Next Birthday

Use the birthday calculator built into the result panel above to see exactly how many days remain until your next birthday, along with the weekday it falls on. It is handy for planning parties, booking leave, or scheduling a surprise.

What weekday will my birthday fall on?

Because a normal year has 365 days (52 weeks plus 1 day), your birthday moves forward one weekday each year, and two after a leap year. The calculator applies real calendar rules, so you never have to count it out manually.

Birthdays on 29 February

If you were born on a leap day, your birthday appears only once every four years. The standard legal convention in India treats 28 February as the birthday in non-leap years, and this calculator follows that rule.

Need the Gap Between Two People Instead?

This page calculates one person's age. If you want the age gap between two people — partners, siblings, twins or classmates — use the dedicated Age Difference Calculator. It compares two dates of birth and returns the gap in years, months, days and weeks.
