Age Calculator
Find your exact age in years, months, weeks, days, hours, and minutes, plus how long until your next birthday.
How it works
Enter your date of birth and the calculator instantly works out your age using today's date, accounting for leap years and the varying lengths of months. Alongside your age in years, you'll see the same span measured in months, weeks, days, hours, and minutes. That's handy for milestone birthdays, forms that ask for exact age, or simple curiosity about how long you've been alive.
