Sort,Count & Sum data based on unique date

[excelkeechak]

I had a worksheet which contains date,Item,Issued/purchased,Qty,Amount in the next columns.

i want to have the Count of the Qty & the sum of the Amount for Issued / purchased seperately for change in date every 3 days.

That is,the data should be sorted in ascending order forming the group of three unique dates each(Entries can be any).
