Calculating Next Months Date for Specific Days of the Week

Hello!

First time  here  hopefully I am on the right board.

I want to figure out a formula to calculate the next month's date for a certain day of the week on column B.

Example - These are all Tuesdays in July, I want to add to this column/ create a formula that would calculate Tuesdays in August. 

I cannot do a fill series as I am working with a template that may have multiple set of weekdays for the month.

Any Macros that would also help?

Thanks in Advance!
