Countifs based on current week

[SplatP1]

Hello,
I need a formula to return the countif based on the current work week (starting on a Monday).
My data looks like this:

[TABLE="width: 500"]

The formula must check that a date in A4:A8 is in the current work week, and return the count of "Y" in the corresponding columns below those that are, to cell A1. In this case, there are 3 "Y" in the current work week (30.07 - 05.08) in row B

Thanks in advance!
