What is an Age Calculator?
An age calculator is a tool that calculates your exact age based on your date of birth and a reference date. Instead of showing only your age in completed years, it can also show the number of months and days you have lived.
You can use today's date to check your current age, or choose a different reference date to find out how old you were on a specific day.
How Is Age Calculated?
- Exact Age: Calculated from your date of birth to the reference date and displayed in completed years, months, and days.
- Total Days: The total number of calendar days between your date of birth and the reference date.
- Days Until Next Birthday: The number of days from the reference date until your next birthday.
