Frequently Asked Questions
How is age calculated?
Age is calculated by finding the difference between your date of birth and the target date. Our calculator shows your age in years, months, weeks, days, hours, minutes, and even seconds โ all updated in real-time.
How do I calculate my exact age?
Enter your date of birth in the field above and click "Calculate Age." The tool will show your exact age in multiple units. You can also specify a different target date to calculate age as of a specific date.
How many days old am I?
After entering your date of birth, our calculator will show your age in days, along with other units like weeks, months, hours, and seconds. The "Days" field shows the total number of days since you were born.
How do I calculate the age difference between two dates?
Enter the earlier date as "Date of Birth" and the later date as "Age at Date." The calculator will show the exact time difference between the two dates in years, months, days, and other units.
Why does my age in days not match a simple calculation?
Our calculator accounts for leap years, which add an extra day every 4 years (with some exceptions). This makes the day count more accurate than simply multiplying years by 365.
Is this tool free?
