HOW TO LIMIT ACCOUNT FOR ONLY 1 WEEK ACCESS : I want to make a subscribtion web simulation for my school task. But I dont know to limit my user account for only 1 week or maybe 1 month.

I tried to search the problem in the internet but I didn't find it

What I'm expected is to make my users have limited time account for just 1 week, so after 1 week my users would like to pay again for another week.
