Chronological Age Calc

Chronological Age Calculator gives a child's age in years, months, and days for standardized assessments. Built for speech-language pathologists, educators, psychologists, and assessment teams.

It is not a general calendar age calculator. It uses the borrow-30 hand method test manuals teach, so the day count can differ from a calendar count by a day or two. The years and months are almost always the same.

What it does:
- Shows the age as soon as a date changes, with total months beneath if you want it
- Takes a date typed on the number pad or picked on a calendar
- Copies the result in the format your report uses
- Follows dark mode and your text size

Private by design:
- Works fully offline; nothing you enter ever leaves your phone
- No history: birth dates, test dates, and results are never saved
- No account, no ads, no tracking

This app is not intended to diagnose, treat, cure, or prevent any disease. It is a calculation tool for determining chronological age.
