Calculate Your Age on Any Date

Many forms do not ask for your age today. They ask for your age "as of" a cutoff date: school admissions, exam registrations, visa and passport applications, sports leagues and insurance forms often work this way. Use Step 2: Age at the date of in the calculator to get the exact answer.

Example: a student born on 3 September 2008 applying for a program that requires applicants to be 18 by 1 September 2026 is 17 years, 11 months and 29 days old on that date: two days short. Checking with the exact cutoff date avoids a rejected application.

How the Calculator Handles Tricky Dates

• Month ends: someone born on 31 January becomes one month older on 28 February (or 29 February in a leap year), because February has no 31st. On 1 March they are 1 month and 1 day older.
• Leap-day birthdays: people born on 29 February turn a year older on 28 February in non-leap years in this calculator. Some laws use 1 March instead, so check the rule if it matters legally.
• Time of day: results count whole days from your date of birth. For a count down to the second, use the age in seconds calculator and add your birth time.

Different Ways to Count Age

This calculator uses the international method: you are 0 at birth and gain a year on each birthday. Not every tradition counts this way. In the traditional East Asian system, a baby is counted as one year old at birth and everyone gains a year at the new year. South Korea officially switched its legal and administrative age to the international method in June 2023, but the older system is still used informally in some places.
