The Chronological Age Calculator gives an exact age in years, months and days as at a specific reference date, which is the format assessments and clinical records require. Enter the date of birth and the date of assessment and the precise figure is produced at once. Educational psychologists, speech and language therapists and paediatric clinicians use it because scoring norms depend on an exact age, and schools use it for placement and eligibility decisions. Leap years and differing month lengths are handled correctly, and the calculation is performed entirely in your browser.
