How to get yesterday date in Delphi

I know you can get the current date and time using the Now() function, but how would you get the date of yesterday?

>Solution :

You can use the Yesterday function from DateUtils as follow:

uses DateUtils;

begin
  ShowMessage('Yesterday = ' + DateToStr(Yesterday)); // Date of yesterday
  ShowMessage('Today     = ' + DateToStr(Date)); // Date of Today
  ShowMessage('Tomorrow  = ' + DateToStr(tomorrow)); // Date of tomorrow
end;

These functions return a TDateTime data type. The time component is set to zero.
