Try the following  double hours    b-a  TotalHours    If you just want the hour difference excluding the difference in days you can use the following  int hours    b-a  Hours    The difference between these two properties is mainly seen when the time difference is more than 1 day   The Hours property will only report the actual hour difference between the two dates   So if two dates differed by 100 years but occurred at the same time in the day  hours would return 0   But TotalHours will return the difference between in the total amount of hours that occurred between the two dates  876 000 hours in this case      The other difference is that TotalHours will return fractional hours   This may or may not be what you want   If not  Math Round can adjust it to your liking
