I have used this calendar for years. I know it is old-fashioned to use an actual, physical calendar, but I don't have a smart-phone, and I just enjoy having this handy. It also gives lots of important dates of saints' feast days, Holy Days for many religions, and civic holidays.
In my work it is important that I am aware of up coming feast days, special days within the church year. This desk calendar is perfect for the task. It has enough room provided to jot down appointment or bit to remember.
