How many calendars do you have in your house? Six, I think (kitchen, my office, family room, DH's office, DS's room, DD's room?)
Do you use a physical calendar? Yes! The kitchen one has all of our family appointments, and my work schedule and DD's work schedule since they are very erratic. The one in my office is a basic 3-month-at-a-time view. I don't write anything on it; it's just a reference for when I'm planning my design/sale schedule.
Do you use an electronic calendar? I've tried, but they just don't work for me.
Have you ever made a calendar? Not lately. When I worked in an office (many many moons ago), I used to just print out basic ones (with a photo of the kids on each month IIRC) and tape them up in my cubicle. I've never made a full blown fancy one.
