I have Sheet3 (named "Sheet1") prepared as reference for the dates (column A) and their month number (column B) with the week number (slightly altered as I need exact week number of the month i.e. week 1, week2, week 3, week 4 or week 5 or the month of May):

"refer to attached screenshot"

What I want to do is get the date fom sheet1 for the expected completion dates and reference it with sheet 3 and count how many codes and record it in sheet 1.

PLEASE PLEASE HELP. *sorry for the sheet naming :(
