If I have a column with 365 rows with each cell representing total sales for each day of the year. If I wanted to find any 30 consecutive days with the highest sum, how could I do that?
 

Excel Facts

Show numbers in thousands?
Use a custom number format of #,##0,K. Each comma after the final 0 will divide the displayed number by another thousand
Interesting. Try:

ABCDE
DaySalesDay30 Day Max
