Subject:      Figuring out Age in Years, Months and Days
In-Reply-To:  <>
Content-Type: text/plain; charset="US-ASCII"

Hi All,

I have a requirement to figure out Age at Death and it has to be expressed in Years, Months, Weeks and Days.

This is to accommodate individuals who may have died a short period after childbirth, etc.

In the past I have used code like this:

Age_at_death=%calcage(birth_date, death_date);

%macro CalcAge(BDtVar, RefDate) ;

floor ((intck('month',&BDTVar,&RefDate) - (day(&RefDate) < day(&BDTVar))) / 12)

%mend CalcAge ;

The DOB and DOD variables are formatted as MMDDYY10.

Has anyone done this type of calculation to this degree?

Many Thanks!
