About Age Calculator
Ages are worked out on calendar dates without time zones, so the result is the same wherever you are. Total hours are approximate because they do not include the time of day you were born.
Is it private?
Yes. Age Calculator runs entirely in your web browser. What you type is never sent to Nolo or anyone else, and the page cannot send it anywhere: its security policy only allows it to talk to nolotools.com, which has no place to receive data. Nothing is stored either: close the page and it is gone. How Nolo works.
Questions and answers
How is the exact age counted?
Whole years first, then whole calendar months, then the remaining days. When a month is shorter than your birth day (born on the 31st), the month ends on its last day, the same way most official forms count.
I was born on 29 February. When is my birthday?
In leap years it is 29 February. In other years the calculator counts it on 28 February; some countries use 1 March for legal purposes.
Does it account for leap years?
Yes. Total days are counted on the real calendar, including every 29 February in between.
Can I find someone's age on a past or future date?
Yes. Change "Age on" to any date, for example a deadline or an exam day.
Are my numbers sent anywhere?
No. Everything is calculated in your browser with JavaScript. Nothing you type is uploaded, stored on a server or tracked, and the calculator works offline once the page has loaded.
