This appointment calendar is used every day for appointments, notations, reminders. I buy the edition with the hard spiral cover because I use it so much every day, but it also comes as a soft cover spiral for less $. This one has sturdy tabs for each month, so you can grasp the tab and flip to the month you want easily. It has a pocket page in the back that I use to store scraps of notes that I'll want for a couple of weeks and can throw away when they're no longer necessary. All in all, it's a great appointment book that I've been using for a couple of decades and prefer above all others I've looked at.
