calculation of number of days between two dates

1. 
   good morning,
2. I have a small problem: I have dates stored in my database in date format, and with two dates I would like to find the number of days between them, so get an integer, how can I calculate that? thank you in advance.

   Hi,
2. You can use the DaysBetween feature. That gives you the number of whole days between two TDateTimes.
3. function DaysBetween(const ANow, AThen: TDateTime): Integer;

   The previous answer is valid if you manipulate the dates in the Delphi code as TDateTime from Delphi 6 onwards otherwise

Difference between two dates

1. 
   The example is made with two TDatetimePicker components that send their values to the variables p1 and p2. Just an addition to what already exists.
