Dates you enter

Your date of birth and the date you choose to calculate on are processed in your browser. This site does not send those dates or your calculated age to its server, Google Analytics, or an advertising service. The dates are not put in the URL, saved in local storage, or written to a cookie. They are cleared when you refresh or leave the page.

If you copy a result, the copied text contains the calculated age, total days, reference date, next birthday, and countdown. It does not contain your date of birth.

Google Analytics

This site uses Google Analytics 4 to understand visits and basic calculator use. It sends the standard page_view event, plus these limited interaction events:

• calculator_started: the event name only.
• age_calculated: status set to success.
• copy_result: status set to success or failure.
• invalid_input: an error_type category, without the value entered.

None of these events includes a date, age value, or clipboard contents. Google's standard Analytics implementation may use first-party cookies and collect general visit information such as browser, device, and approximate location. Read Google's Analytics data collection overview and GA4 cookie information.

Advertising and payments

No advertising network or payment service is currently active on this site. The reserved advertising area does not load an advertising script.
