Calculating dates in Approach97

Calculating dates in Approach97

Calculating dates in Approach97

Please tell me if it is possible and if so the formula to subtract one date field from another and get the number of years for an answer.  Thanks.

RE: Calculating dates in Approach97

Subtracting one date from another gives you a number answer equal to the number of days between the two dates. Divide that number by 365.25 to get the number of years and a fraction.

Something like this:
NumYears = (date2 - date1)/365.25

To eliminate the fraction do this:
NumYears = Trunc((date2 - date1)/365.25)

RE: Calculating dates in Approach97

I'm trying to do something similar to this question and can't seem to find the correct formula. I have an Age field that I want calculated from my Date Of Birth Field automatically. But I need it to be how old was that child on December 31, 2002. When I changed my date on my computer to say 12/31/02 and in the value section of my formula I put the following:

(Today() - DOB) / (365.25)

It puts something like 10.945666 and I just want it to say 10.

What am I doing wrong?

Thanks for your help in advance!!!!!!!!
