Thinking about this more, you should use the UtilDateTime.toCalendar(...) method to construct two
Calendar objects, then use them for the comparison.

Why not compare the milliseconds value?

The problem with that is that comparing datetime means that 10/06/2006
12:00:01 != 10/06/2006 18:30:00. I just want to see if a Date is the
same, before, or after another. The time messes up the tests.
I think using the commons/validator is the right thing to do since the
less code we write, the less we have to maintain. On the otherhand,
my method is short and sweet.
/**
* compares two dates (excluding time) to determine if date A is
equal, before or after date B
* @param dateA a java.util.Date object
* @param dateB a java.util.Date object
* @return int a value of zero (0) indicates the dates are
equal; a value less than zero (< 0) date A is prior to B; and a
* value greater than zero (> 0) indicates date A
occurs after B
*/
public static int compareDates(java.util.Date dateA, java.util.Date
dateB) {
String strDateA = UtilDateTime.toDateString(dateA, "yyyyMMdd");
String strDateB = UtilDateTime.toDateString(dateB, "yyyyMMdd");
return strDateA.compareTo(strDateB);
}
