running total for last 7 calender days
I have a pilot logbook in excel. I need to find total hours in the last 7
calender days. |
Where are the hours, in a separate column like if you would have the dates
starting in A10 going down the hours would be in for instance B10 going down? If so use =SUM(OFFSET($B$10,COUNT(B10:B1000)-1,,-7,)) format as general if decimal values and as [hh]:mm if time values If in the same cell like 03/01/05 02:00 for 2 hours on March 1st, then use =SUMPRODUCT(MOD(OFFSET($A$10,COUNT(A10:A1000)-1,,-7,),1)) with dates and times in A -- Regards, Peo Sjoblom "md83" wrote in message ...
