Your exact age today
This is the everyday "how old am I" calculation: give your date of birth and Ageifier returns your precise age in years, months, and days. Need your age on a different day — a wedding, an application deadline, a child's checkup? Set the second date and the answer updates instantly. The tool also tells you the weekday you were born and how many days you have been alive.
Frequently asked questions
How do I calculate my exact age?
Enter your date of birth and Ageifier shows your exact age in years, months, and days as of today. You can also set an "as of" date to find how old you were, or will be, on any other day.
How does the calculator count months and days?
It counts whole calendar years and months first, then the remaining days — the same way you would read an age off a calendar. Leap years and months of different lengths are handled automatically.
Can I find out what day of the week I was born?
Yes. Along with your exact age, the tool shows the weekday you were born and the total number of days you have been alive.
Is my date of birth stored anywhere?
No. The calculation runs entirely in your browser. Your date of birth is never sent to a server or stored.
