No, don't have one. We do stick appointment notes on the fridge sometimes, but I generally use my phone for logging appts/important dates. Don't wear a watch either (once i put them on they don't keep time). For work stuff I print out my roster/make notes on it. Used to have calendars for years, but we sort of drifted out of using them once the new kitchen went in (no wall space for a hanger). My mother has a calendar which she checks/uses almost daily.
