Split time in arbitrary periods, EXCEL
- by Gabriel A. Zorrilla
I have a list with date and quantity of items used
IE:
2009.03.18 -1
2009.06.05 -2
2009.06.22 -1
2009.06.29 -2
2009.07.14 -1
2009.07.14 -1
2009.07.14 -2
2009.07.20 -2
2009.07.30 -1
2009.07.30 -1
2009.08.06 -1
2009.08.26 -1
2009.09.15 -1
2009.09.16 -2
2009.09.22 -2
2009.09.23 -2
2009.09.30 -2
2009.10.07 -1
2009.10.08 -2
2009.10.22 -1
2009.11.06 -3
2009.11.17 -2
2009.11.20 -1
2009.11.23 -2
2009.11.23 -1
2009.11.25 -2
2009.11.27 -1
2009.12.02 -2
I need to know how much items i consumed in a determined period, ie, 15 days. I can do it in a monthly basis, basically using the month function to extract the month and work from there, but with an arbitrary time (which is the average lead time from my supplier) dont know how to get a function to split the date list in chunks of 15 (or whatever) days.
Any tips?
Thanks!
