Calculate age based on date of birth.

Hi,

In a tabel I want to calculate the age of people based on the date of birth.

Today it is the 5th of november 2004.
When the date of birth is the 6th of november 1965, the age should be 38.
But it is calculated as 39.

procedure TDM.TRelatiesCalcFields(DataSet: TDataSet);
begin
If DateToStr(DM.TRelaties.FieldByName('Geboortedatum').AsDateTime)<>'30-12-1899' then
DM.TRelaties.FieldByName('Leeftijd').asInteger:=YearsBetween(Now,DM.TRelaties.FieldbyName('Geboortedatum').asdatetime)
else
DM.TRelaties.FieldByName('Leeftijd').asInteger:=0;
end;

Can anybody finetune my calculation?

Thanks Stef

Hi,
Try
YearsBetween(DateOf(Now),DateOf(DM.TRelaties.FieldbyName('Geboortedatum').asdatetime))

The following depends on how you populate your table, and whether you are using the BDE.

You don't have the Regional settings set for the wrong country perchance?  (Or ditto with the BDE, but not both)

If this is the UK (with US date format) then you would get:-

11 May 2004
11 June 1965

which is 39 complete years.
