Should, but I am not sure.
I'm not entirely sure what I'm doing. But this is what I have so far but I'm not sure how to get it to check a file for the date. As well as a lot of other things.

The timer doesn't do anything for you unless you specify what it should call when the interval lapses.
Otherwise, make sure you do not have to declare GC as well.
Yeah, that wasn't a finished product. I just wasn't sure what comes next. I'm guessing it supposed to call the file that holds the email dates, which I do not have as of yet. What is supposed to be holding that?
No, it calls the function on the same page.
Set the interval and target it to the function. It will automatically run the function.
Do, I need to have an array with the different dates? Excuse me if sounds like I'm talking out of my butt, because I probably am.
