You may use this site to compute chronological age for personal or professional notes. The service is provided as is, without a warranty that a figure will match a publisher's scoring software.

Results are informational. They are not medical, educational, or clinical advice. If you are scoring a standardised test, follow that test's manual. If the manual and this site disagree, the manual wins.

Fun facts are estimates based on published averages and constants. They are not measurements of your body or of events in your life.

The site is run by Abhishek, an independent developer in India. Contact hello@chronologicalage.online.
