For as long as I can remember, I have been deeply fascinated with calendars. I am sure it is based in part on my deeper fascination with time itself—as a concept, as a construct, and as a constant. I think it may be the false sense of predictability calendars offer—they give a glimpse into the future, but aside from holidays and plans, that glimpse is ultimately always a bit empty and never guaranteed.
Several years ago, I discovered the concept of re-using calendars thanks to their predictable repetition. So far, mine is a new, strange, tiny collection. As years come to an end, I take down the calendars off the wall over my desk and the one in my kitchen, then pack them away to be used again. On the back, I write the coming years in which they will sync up again, giving them the potential for future use for anyone who comes across them.
For example, in place of a 2011 calendar, you could have used any Gregorian calendar from 2005, 1994, 1983, 1977, 1966, 1955, 1949, 1938, 1927 and 1921. That is a great line of available calendars. I am trying to track down a copy of a 2011 Betty White calendar I used to have so that I can use it in 2022. I recycled mine before I fully understood I’d be able to re-cycle it in eleven years. To be clear, your holidays and time changes won’t always line up, but the days and dates will be just fine.
Due to 2020 being a leap year in which February 29 landed on a Friday, this year’s calendar is only reusable three times in the next 96 years, in 2048, 2076, and 2116, when leap day returns to Friday. And only four calendars from the 20th century could have been used in place of one from 2020—those from 1992, 1964, 1936 and 1908. This is the same story for every leap year, they’re spaced apart a minimum of 28 years.
It’s a simple fascination that I don’t spend too much time on. I do wonder, though, if it is possible to build a permanent collection so that I have all the calendars I will ever need. Then again, do I really want a complete collection? There is something so morbidly finite about that.
Here are my two resources on this subject. The best, no frills site for quickly looking up which calendars to reuse is whencanireusethiscalendar.com. And one of my favorite sites to waste time on all thing time and dates, and even repeating calendars is timeanddate.com
I do think it would be a nice trend to write the future years of re-cycle on the backs of our calendars from now on. Even if you don’t keep them, a like-minded collector will be glad you donated them to a thrift store. I now have a 1993 calendar I plan to use in 2021, 2027 and 2038.
To be honest, I am seriously considering burning my 2020 calendar at 11:59pm on December 31. No one should ever have to spend another calendar year with 2020.
