Eight years ago, I lifehacked my way into replacing the desktop picture on my Mac with a calendar showing an entire year at a glance. Each year since then, I'd scavenge my next wallpaper and "borrow" a design from someone else.

 

Now it's time to give back.

 

Sized for the iMac 5K Retina display, and available in three color profiles, feel free to use one or all of them. I'd also be delighted to customize the design if anyone is interested.
