"I’ve been watching this post since it went up. To be honest, I’m kind of shocked that someone would even ask this question. Don’t we all have important dates that we PUT ON THE CALENDAR? Isn’t that just a common sense everyday thing? "
You had a 48-month or 60-month calendar handy? Good for you. I will be quite frank – I have never seen a 48-month calendar. I have not seen a 60-month calendar. I asked the two questions in the OP based on the fact that my time-frame was further out and sought advice that might be helpful for others who might be in a similar situation. That is, figure out a process to remind oneself of an important date multiple years out.
