My DH is a photographer and he makes a calendar each year so we always have one of those hanging in the house. We don't really use it much though, we use our phone calendars for most appointments. I also keep a day planner type calendar in my purse, mostly because my phone is pretty terrible and I don't entirely trust it, so I enter all my appointments in there as well.
I use a lot more calendars at work. I have a big one that lists all the company holidays and important dates such as dates for new software release loading, etc. I use my Outlook calendar for all my meetings, of course, and then I have a day planner style one I keep on my desk that has my personal appointments, reminders, etc. in it. Then there's a departmental calendar that everybody shares for scheduling vacation time.
