I hope you haven't thrown away all your nice 1986 calendars. You can reuse them in 1997. And you can reuse your 1996 calendars in 2024. You have a pile in that spare bedroom closet that you saved because you wanted to frame one of the pictures, don't you? See if there is a 1986 in there somewhere. Hang it up at work and explain "It's the same as 1997." Impress your co-workers with your savant catendrical ability. Amaze your dentist by telling him you had an appointment on a certain day eleven years ago. Enjoy eleven year old calendar graffiti memories. You can reuse calendars in 6 or 11 years, depending on leap year patterns. Use the chart below to plan ahead so you can give old calendars as gifts to those special family members.
