Hey Jon. Here is what I ended up doing.
I placed the 42 individual calendar cells in their own unique composition.
I then nested those 42 individual compositions inside a 2000x2000 composition. I aligned the 42 individual calendar cell comps into the shape of a calendar and made them 3d layers. Seven rows. I then animated each individual calendar day falling to the ground. You can animate these however you like. I animated them starting at the right most cell on the bottom row.
Once I had the entire calendar falling to the ground I just duplicated the 2000x2000 composition 11 times. I then offset the time of the 11 layers to play after the layer before it had completed animating.
To make the pile on the ground look more unique. I faked the pile at the bottom. I created a pile of calendar cells in another comp and had them pop on screen after a few of the calendar sheets had fell.
If you have any questions just ask. I realize it's not the easiest solution nor does it have any expressions, but I was short on time and had to get it done.
