Birthday calculator

When you use the calculator, your date of birth is used on the page to produce results. It is not stored by us as part of that calculation. After you calculate, the address bar can update to a shareable path like /birthday/1999-12-05/ so you can copy and share a link to that date. Those paths are not listed in the sitemap; they can still be indexed if someone links to them.

Analytics

Analytics are off by default. If enabled later, we may use Google Analytics (gtag.js) to collect basic visit information (for example which pages were viewed) and calculator events that include the date you entered, so we can see which dates are popular. Events do not include names, emails, or other account profile data.

Advertising

Google AdSense is disabled by default. If enabled, advertising partners may use cookies or similar technologies according to their policies and any consent configuration the site adds.

Affiliate links

Some pages may include Amazon Associates affiliate links. Clicking those links may allow Amazon to know you visited from this site. Affiliate clicks are not tied to your birth date.

Consent management

A certified consent-management platform may be added before personalized advertising is enabled. This site does not ship a fake consent banner.
