Calculate your exact age in years, months and days by entering your date of birth. Simple, fast and accurate.
The calculator counts full years, months and days from your birth date to today, handling leap years and month lengths correctly — something mental math gets wrong near February 29.
Exact age matters for benefits, contracts, age-restricted services and medical dosing where a few days can change eligibility.
Subtracting years only and calling it "your age" on the birthday you have not reached yet. The precise count waits until that date actually arrives.
Why does it show months and days? Many forms ask for age in years-and-months (e.g. 34y 2m); the breakdown answers that exactly.
Does it account for time zones? It uses the calendar date, which is what legal age is based on.
