# IsSameDay

**IsSameDay** performs a test comparing the **TDateTime** value specified in **AValue** with a second **TDateTime** date specified by **ABasis**.

**True** is returned if the dates match, or **False** if they do not match.

The value does not include time, which is set to 00:00:00.

Declaration: Function IsSameDay(const AValue, ABasis: TDateTime): Boolean;

A example showing the function used along with **FormatDateTime**. In this example, the test will fail and return **False**.

```pascal
procedure ScriptEvent (var Value : variant);
var
  ADate : TDateTime;
begin
  ADate := IncDay(Date, 7);

 if IsSameDay(ADate, Yesterday) then //This check will fail
    LogInfo('The dates are the same.')
 else
    LogInfo('The dates are NOT the same.');

    LogInfo('The date is '+FormatDateTime('dd/mm/yyyy',ADate));
    LogInfo('Compare date is '+FormatDateTime('dd/mm/yyyy',Yesterday));

end;
```
