b/2293263 Replaced busybit functionality with eventDay functionality.

Made changes to start stripping out busybits and replace them with checks only to see if an event eists on a given day.
This file ties into several other areas so not all busybits references were removed and those that were have been
commented out to make it easier to find errors.
