About Age Calculating
Free, accurate, privacy-first age and date tools — built by people who actually care whether the math is right.
Who we are
Age Calculating is a small independent project. We build single-purpose calculators that solve one problem really, really well — without sign-ups, paywalls, or surveillance. Our team of writers and engineers shares a background in education, software, and data journalism; we built this site because every other "age calculator" we tried either guessed at the math, sold our birthdays to advertisers, or buried the answer under banner ads.
What we believe
- Privacy is the default. Your date of birth is sensitive personal data. We never collect it, never log it, and never share it. Calculations happen in your browser.
- Accuracy is non-negotiable. Every formula is checked against authoritative sources — NASA planetary fact sheets, the Pew Research Center, the American Academy of Pediatrics, the Bureau of Labor Statistics — and the methodology is published right next to the calculator.
- Speed is a feature. Pages load in under a second on a slow connection because we serve plain HTML and a tiny amount of JavaScript. No frameworks shipped to your browser.
- Free forever. The site is supported by unobtrusive advertising. We will never put a tool behind a paywall.
Editorial standards
Every long-form article on this site is researched against at least three primary sources, fact-checked by a second editor, and dated. We publish corrections openly: if you find an error, write to us at [email protected] and we will update the page (with a visible correction note) within 48 hours.
How we make money
We display a small number of clearly-labeled ads from reputable networks, and that is it. We do not sell user data because we do not collect any. We do not run sponsored content disguised as editorial. If a calculator ever links to a third-party product, the link will be marked as an advertisement.
