RE: [MS_AccessPros] Age calculation




If you work in both Excel and Access, working with date information can be confusing. As Duane has pointed out the Access Date() function returns the current date. Access does not have a Today() function. The Excel Date() function returns the serial number for the y,m,d arguments you send to the function. It is common in Excel to simply subtract one date from another. As John has pointed out, we use the Access DateDiff() function to perform that sort of operation.

Use the DateDiff expression or the Age function on the page Duane pointed out.  The CalcAge Sub uses additional arguments to return its calculations, so it won't work called from a query.

You've missed on basically all cylinders. You are close to getting the age in days, not years. Date() returns today's date. You should also make sure DOB always contains an actual date.  


Most of us use a function of expression like http://access.mvps.org/access/datetime/date0001.htm

I am using Access 2013.

I need to calculate a person's age, rounded to complete years, as at 'today'.

I tried this:Age:( (Today()-[DOB]) and I see an error message.

What have I missed?

Many thanks,

Robin Chapple
