I am trying to calculate the amount of time on a daily basis.

Currently I have calculated "[total hours per diem]", "[total days]" and the time values (if not split over multiple days).

Where I am having trouble is in calculating the total time spent if the event is not an "all day event" and falls over multiple days.

For example:

If I had 1/1/2013 12:00 PM (Start Date) and 1/2/2013 4:00 PM (End date). I would like to have the result be 8 hours ((4 hours per day day) * (2 days)). What I actually end up with is 28 hours (the difference between the two times).

It should be something like =([total days]*(*time difference of end time - start time)) but I can't figure out how to just pull the time for a single day.

Thank you in advance

var startDate = Convert.ToDateTime("1/1/2013 12:00 PM");
var endDate = Convert.ToDateTime("1/2/2013 4:00 PM");

var diffHours = (endDate.Hour - startDate.Hour);
