Many people I know work two weeks on, two weeks off; this calendar is a quick way display such a rotation.
You can send people links, here is my rotation and they know if you’re on work or not. It is also design to fit on a A4 page for printing.
Any suggestions or feedback regarding it, please send me an e-mail!
