Age Calculator
Find an exact age in years, months and days — plus totals and your next birthday.
Free online age calculator
The Ajenza Age Calculator works out an exact age from a date of birth, right in your browser. It shows the age in years, months and days, and also the totals — how many months, weeks, days and hours old you are — the day of the week you were born, and a countdown to your next birthday. Change the "age at date" to find how old someone was, or will be, on any specific day. Everything is calculated locally and your dates are never uploaded.
Is it free?
Yes — completely free, with no sign-up, download or watermark.
How is the age worked out?
It counts complete years, then the remaining months and days, accounting for different month lengths and leap years.
Do I need to install anything?
No. Everything runs in your browser.
