    Calculating total time spent by half hour

    Hi,
    I cannot figure out a formula to determine how to calculate time spent in a half hour interval, when the time is overlapping. To exemplify, [Cell A1] has a start time of 12:07am: [Cell b2] has an end time of 12:37 am. I need to calculate how much time of this duration was spent between 12:00am and 12:30 am; 12:30 am and 1:00 am. Obviously, I can do this manually. However, I have thousands of rows that I need to calculate the duration of certain states in a call center were spent by half hour interval. Any advise would be greatly appreciated.

    Re: Calculating total time spent by half hour

    I've posted an Image below. I am thinking the half hour intervals go horizontal. So in row 2 would show how much time equates for each half hour. If there's a better way to do it. I'm totally open. However, the Start time and End time are like this.

    A B C D E F
    1 Start_Date End_Date 12:00 AM 12:30 AM 1:00 AM 1:30 AM etc…
    2 12:13:27 AM 12:13:51 AM
    3 12:15:56 AM 12:16:13 AM
    4 12:26:42 AM 12:27:52 AM
    5 12:30:21 AM 12:31:18 AM
    6 12:33:29 AM 12:33:40 AM
    7 12:39:13 AM 12:39:24 AM
    8 12:41:42 AM 12:42:11 AM
    9 12:44:38 AM 12:45:00 AM
    10 12:52:26 AM 12:52:43 AM
