Age Calculator
How old are you exactly? This age calculator takes your date of birth and computes your precise age in years, months, and days. It also tells you the total number of days and weeks you have been alive, and how many days remain until your next birthday.
Calculating age seems simple but involves subtleties around varying month lengths and leap years. This calculator handles all of those correctly by working with actual calendar dates rather than simple arithmetic.
The calculator provides:
- Exact age broken down into years, months, and remaining days
- Total days alive for a precise count
- Total weeks alive for a different perspective on your lifespan
- Days until next birthday so you know exactly how long until your special day
Enter your birth year, month, and day using the number fields. The calculation is performed against today's date automatically.
