About This Age Calculator
This free age calculator tells you your exact age in years, months, and days, plus the total days, hours, and minutes you have lived. It also shows how many days remain until your next birthday and which day of the week it falls on. Everything runs in your browser, so no data is sent anywhere.
Most age calculators only show your age in years. This one gives you the full breakdown, and you can change the calculation date to find your age on any past or future date.

Common Use Cases
1. Forms and Applications With an Age Cut-Off
Job applications, school admissions, and exams often ask for your age in years, months, and days as of a closing date. Set "Age at Date" to that date to get the figure to enter. Always follow the rule stated by the organization, since each one defines its own cut-off.
2. Planning Birthday Celebrations
The countdown shows how many days remain until your birthday and what day of the week it falls on. Useful for planning parties, booking venues, or coordinating with family.
3. Curious Statistics
How many days have you lived? How many hours? The totals are surprisingly large and make fun personal milestones.
4. Past or Future Age Calculations
Want to know how old you were on a specific past date, or how old you will be on a future date? Change the calculation date and get the exact answer.

- Total days: 11,450 days

How Age Is Calculated
The calculator counts full years first, then the remaining full months, then the remaining days. Leap years are included in the day counts.
If you were born on February 29, your birthday is counted on February 28 in years that are not leap years. Some jurisdictions use March 1 instead, so check the rule for your document if the exact date matters. This tool is for general information and is not legal advice.
