I've used this calendar each year on a bulletin board next to our landline phone in the kitchen for a couple of decades. Every appointment with doctors, plumbers, furnace repairmen, auto service, the veterinarian, etc. is noted. The calendar is filed in a filing cabinet at the end of the year and thus it becomes a "diary"available for reference. Birthdays of family and friends are written in red ink from one year to the next ... truly red letter days in this house. This calendar is an efficient size with excellent paper for my purpose and I highly recommend it.
