How do I Reset Localstorage Data Every Week?

So I got confused about how to realized this, I want to reset some localstorage item every new week.

So, if player was playing at Thursday, and then playing again at next week, their data will be reseted.

But when they play in the same week, the data still increasing until they play in another new week.

Thank you!

I made a demo:
