Well, I only glanced at it...but it seems a little too simple for me. It seems like all the "planning" for each holiday/even is done at the beginning of the month of that holiday. Not really planning too far ahead if you just start thinking about when Spring Break is on March 1st. Our spring break is in March and it might already be too late to get reservations if you were planning a hotel/plane type trip. I realize not everybody takes big trips for Spring Break...just using it for an example.
Around here if you wait that long, the holiday things are already getting picked off the shelves, too.
