What Is This Tool?
Our age calculator tells you your exact age in years, months, and days from any birth date to today or any other target date. It handles leap years and month length differences correctly, giving you a precise answer rather than a rough estimate. Use it to find out how old you are, how long until a birthday, or the age difference between two dates.

- By default, the calculator uses today's date as the target date.

Frequently Asked Questions
Does the calculator account for leap years?
Yes. It calculates the exact number of days between two dates, including any leap years in the range, so the years/months/days breakdown is always precise.
Can I calculate the age difference between two other people, not just myself?
Yes. Enter one person's birth date as the birth date and the other person's birth date as the target date to see the exact gap between them.
How do I find out how many days are left until my next birthday?
Set the target date to this year's (or next year's) birthday date. The day count in the result shows exactly how far away it is.
Why does my age in months not divide evenly?
Months have different lengths, so the calculator counts a full month as having passed once the same day-of-month is reached, then reports any leftover days separately — this matches how age is conventionally described.
Is my birth date stored or sent anywhere?
No. The calculation happens entirely in your browser, and no date you enter is saved or transmitted.
