Thanks Rob, your idea has definitely made this thread useful again lol. I might just do that then. But do you think the idea about using 2015's calendar in 2017 would work if you crossed off all of the days and numbers with a pen and wrote down the new days corresponding with the correct numbers? Thanks again. Ted 
If the calendar overlaps the weeks like in the example below then you can just change the date numbers.

If you have access to a printer you could print out stickers to make it look a bit neat than crossing out with a pen and if the stickers peel off easily then you could reuse it again and again.
If you do your own via one of the online services then don't forget to post some photos here.
