Quick Answer

To calculate your age, subtract your birth date from today. Your exact age is the difference in complete years, remaining months, and remaining days. For example, if born January 15, 1990, and today is December 9, 2025, you are 35 years, 10 months, and 24 days old. Our calculator instantly computes your age in years, months, days, weeks, hours, and even seconds.

  • Chronological age differs from biological age (health-based measurement)

Frequently Asked Questions

Age is calculated by finding the difference between the birth date and the current (or target) date. We count complete years, then remaining months, then remaining days. This gives you the most accurate representation of your exact age.
Different calculators may handle edge cases differently, such as leap years or months with varying days. Our calculator handles these correctly: if your birthday is February 29 and it's not a leap year, we calculate based on March 1.
The calculation is accurate to the day. It finds your next birthday based on the current date and calculates the exact number of days remaining. On your birthday, it will show 0 days until your birthday.
Yes! You can enter any date as the birth date and any date as the target date. This allows you to calculate how old someone was at a specific point in time, or how old they will be on a future date.
Total days is the exact number of days between the birth date and target date. Total weeks is simply total days divided by 7. These calculations account for leap years and different month lengths.
