This is a simple board of many items, I keep up my calendar year around. You can get these calendar kits at Hobby Lobby or Office Depot, they come with a birthday cake to display birthdays for the month, season wheel, holidays and weather cards. The numbers are hung on straight pins for easy change out, just use a hole punch to punch a hole in the number cards. Click pictures to enlarge.
The following boards I worked out on the computer for reference.
