I need to calculate, in decimal hours, how many of the hours from a specified range, fall within another specified range. For example, for each of the ranges below, I need to know how many decimal hours fall between 07:00 and 17:00:
07:00 to 19:30
09:30 to 16:30
07:00 to 14:00
09:30 to 19:45
Please help!
