Chronologic Age

The difference between the individual's date of birth and a specific later date. Note: Chronologic age may be expressed in varying degrees of precision and can be derived from computer programs that report age values using multiple significant digits. To correctly interpret and report results, consultation with a statistician may be necessary.
