I always forget the outcome of the DateTime.Compare method; Compares two instances of DateTime and returns an integer that indicates whether the first instance is earlier than, the same as, or later than the second instance. Just a reminder to myself ;) The result of the next piece of code:

int result = DateTime.Compare(date1, date2)

result is less than zero : date1 is earlier than date2. 
 
result is zero : date1 is the same as date2.
 
result is greater than zero : date1 is later than date2.
