Excel/Given Birth Dates : Require Age


Dear Aidan,
From the application forms received from my wife's new students (a Ballet School) I will enter a 'Date of Birth' column in her spread-sheet 'Student Database'. I would like an adjacent column that would self-calculate and then show 'Age Now'. What would you suggest, please.
Yours sincerely,
Gary Fraser.

I'd use the YEARFRAC function - in older versions of Excel this wasn't native, so you'd have to use tools, add-ins to add in the Analysis ToolPak - later versions have it as standard.  The format is (specifically for your case)


where A1 is the student date of birth cell.   this will return an exact age in years and a decimal fraction for part years - if you only want the whole number use

I have provided first hand support since `95 for Microsoft Office majoring in Word and Excel - support for all versions from 2 onwards. I'm based in the UK, so please allow for time differences when asking me questions from other parts of the world!


My background is in the insurance industry and call centre areas, but have been called upon to provide many varied solutions.

I'm educated to UK A level standard, but as I left school some 30 years ago that is rather irrelevent - university of life has provided more of a background!
