How do I create warning message that pops up every half a year?

I have to make an app for students that have their own study path but every half a year they can change it so I want to make a warning message that pops up with a time indication but I don't know where to find it pls help me.

I would create a microflow on the home page, that retrieve the date of the moment the user choose the path, checking if the current date is half a year or more, if so, display a pop up.
