What this tool does
Exam and job notices fix an age limit “as on” a cut-off date, for example 1 August. This calculator gives your exact age in years, months and days on any date you choose, plus total months, weeks and days, and how long until your next birthday.
How to use it
- Enter your date of birth.
- Leave “Age on” as today, or set the cut-off date from your notice.
- Read your age in years, months and days.
- Compare with the age limit in the notice.
