About Us

Every tool here starts from a date and works out something useful: how old you are, how many days sit between two dates, how many of those are working days, when a countdown ends, when a projection lands.

The site exists because that arithmetic is genuinely awkward to do by hand. Months are unequal, leap years are irregular, and several common questions have two defensible answers rather than one. Most calculators pick one answer silently. This site names the convention it used, on the page, and shows the alternative where one exists.

Whats My Age is written, designed, built and maintained by one person, publishing as Liam Cooper. There is no team, no agency and no syndicated content.

I am not a lawyer, a doctor, a vet or a financial adviser, and nothing here is professional advice, see the Disclaimer for what that means in practice. What I can do is arithmetic carefully and explain the conventions behind it honestly.

The site is a set of static pages. Every calculator runs entirely in your browser using ordinary JavaScript, there is no server-side calculation, so the dates you type are never sent anywhere. Nothing is stored and nothing is logged by us.

There are no accounts, no registration capture, no paywall and no upload step. Each page loads, works immediately, and keeps working if your connection drops.

Dates are handled on the real calendar rather than by converting to days and multiplying. Leap years follow the full Gregorian rule including the century exceptions, month-end arithmetic clamps to the last valid day, and day counts are normalised to UTC before subtraction so a daylight-saving change inside a span does not shift the result.

Advertising. The tools are free to use, there is no paid tier, and advertising is what covers hosting and the time spent writing the material. Ads are clearly separated from content, and no ad placement changes what a calculator returns or what an article says.

The Privacy Policy sets out what advertising means for cookies and data, and how to control personalisation.

If a calculation is wrong, or an article states something inaccurate or out of date, I want to know. Use the Contact Us form with the dates you entered and the result you expected. Confirmed errors get fixed, and pages that change materially carry an updated date.
