The Periodic Calendar is an ingenious calendar design that can be used for any year in the past, present, or future (video). The calendar works by categorizing years based on which day of the week they begin with (in essence there are only seven “types” of years.) The calendar was designed by artist Joey Sellers. He is raising funds on Indiegogo to finance the first print run.
