Chronological Age Calculator

A free, no-signup calculator for speech-language pathologists, school psychologists and teachers who need a child's exact age on a test date. Enter a date of birth and a test date and get the age in years, months and days (Y;M;D), the format standardized test manuals expect. Includes batch mode for a whole caseload, an adjusted-age calculator for premature infants and an MLU calculator for language samples. Everything runs in the browser; nothing is uploaded.
