Make a don't break the chain application

Would be cool to have a large calandar.
I can go over the calandar and x out certain days.
At the end of the month the calandar becomes small and hides in the upper left corner.
I'll be able to go through each of these past calandars if I so wish.

Better yet. It'll just be a year calendar. With the ability to go back to old years that have data.
