    Sum number of calls within a specific time frame

    I have created a pivot table which properly display the time of day and the number of calls at that time. (There happens to be only one call per minute but in theory there can be multiple calls made in the same minute). I have tried to sum the calls by hour using countif and a variety of other things. Any help would be appreciated! Below is an image of what I am trying to calculate and the sample excel sheet is also attached.

    Re: Sum number of calls within a specific time frame

    Hi and welcome to the forum

    The main reason you cannot get the count to work is because the times in your summary table are just that - times. But the times in your data table are dates AND times...

    To get past this, I used a helper column D (you can put it where ever you want, and then used this, copied down...
    =MOD(A3,1)

    Then to get the summaries, use this in the summary table, copied down...
    =COUNTIFS($C$3:$C$1056,">="&E3,$C$3:$C$1056,"<="&F3)

    I did notice that the totals did not match, and found out that you have some times that have seconds inthem that the above does not catch. Sor change the "end" time to hh:mm:59 - 12:59:59 AM etc

    hi t83357. other alternatives:
    in G3
    =SUMPRODUCT((FLOOR(MOD($A$3:$A$1056,1),"0:01")>=E3)*(FLOOR(MOD($A$3:$A$1056,1),"0:01")<=F3))

    or do a Pivot (which you mentioned you did?). just right-click the Time of the day & Group. Choose Hour & take out Month.
