Sick of switching your wall calendar with each month, and replacing it entirely every year? This sliding version is so simple you have to wonder why it is not in every home already.
There is a live demonstration version on designer Ilya Birman‘s site, but put simply: you can slide a secondary panel back and forth to accommodate the changes in start dates with each month, for any month, of any year.
With weekends highlighted in red, there is no need to even put days of the week in letters, making this a language-independent design. The catch? Not every month has 31 days, so you will need to keep track and switch accordingly – whether this is a fatal flaw or a version-one bug remains to be seen.
