Formula to pull most current weekly data to a monthly sheet

[1TruKing]

So I have 2 pages one is broken down with weekly data and I have another page that has monthly data but I want to pull the most current weekly data. Weekly columns would be identified as example 8/4 8/11 8/18 and Monthly is just August 2017. Is there a way to pull the most current 8/x data to the August column but not pull September data when that starts being added.
