How to use TODAY function to cover an entire week?

I'm creating a Gantt chart in Excel that covers a weekly agenda (starting on Mondays), and want to highlight the current week. I've attached a screenshot of the chart in case this description isn't clear.

Is there a way for me to use the TODAY function to highlight which week of this month it is? Or is there another way to create this formula using conditional formatting? I'm imagining that I can create a rule that will highlight each weekly column if today is within that given week, but don't have the skills to do this.

Thank you!
