Free chronological age calculator for Pearson assessments — enter a date of birth and test date for the exact age at testing in years, months & days. No sign-up.

Hey Product Hunt 👋 I built this because working out an exact age — years, months, and days — is surprisingly fiddly. Educators and psychologists need it for "age at testing" on assessments like the WISC and WIAT, parents need it for school cut-offs, and forms often ask for it too. Most tools online bury the answer under ads or ask you to sign up. So I made one that just does the job: enter a birth date (and test date if you need it), get the precise chronological age instantly — plus total months, weeks, days, and a birthday countdown. It's free, runs in your browser, no sign-up, no watermarks. It's part of OneTapTool, a small collection of free tools I'm building. Would love your feedback on what to add next 🙏

Finally a no-fuss age calculator that actually gives years, months, and days without making me sign up or watch an ad.
