I kept running into forms—school assessments, eligibility paperwork, compliance stuff—that asked for age "in years, months, and days" as of a specific date. Not "about 5" or "born in 2019," but the exact breakdown. Doing that by hand is easy to get wrong (leap years, different month lengths), and for things that get checked or audited, being off by a few days can matter. So I built a small tool that does one thing: you enter birth date and the "as of" date, and it gives you the exact chronological age. No signup, runs in the browser, and it’s become the thing I (and a few colleagues) use whenever we need that number for Pearson, Brigance, or any form that wants it. Hope it saves someone else the head-scratching too.
