Calculate your exact age in years, months and days, and find out how many days until your next birthday.
Most of the time, saying you're a certain age is enough. But occasionally something asks for more precision — a visa form wants your age in completed months, a medical record needs your exact age on a specific past date, or you're just genuinely curious how many days you've been alive.
Enter your date of birth and this calculator gives you your exact age in years, months, and days as of today — or as of any other date you choose. It also tells you the total number of days you've lived and counts down to your next birthday.
Parents tracking infant development in months, people checking age eligibility for super access or pension entitlements, and anyone settling a 'who's technically older' argument will all find it useful.
Yes — change the 'As of Date' to any past or future date. Useful for confirming age at a specific event, checking eligibility for something with a date-specific requirement, or working out your age on a particular milestone.
For infants and young children, age in months is the standard unit for developmental assessments, vaccination schedules, and medication dosages. This calculator gives that exact figure.
Yes. The calculation accounts for leap years and variable month lengths, giving you an accurate result regardless of when you were born.
Leap day birthdays are handled correctly. In non-leap years, the birthday countdown treats February 29 birthdays as falling on March 1.
