إقتباس :Call CompareDate to compare the two TDateTime values specified by A and B. CompareDate returns:

LessThanValue if A occurs on a day prior to the day specified by B.
EqualsValue if A occurs on the same day as B, ignoring the time of day.
GreaterThanValue if A occurs on a day that follows the day specified by B.
