One thing that makes it much easier to read on a calendar regardless if it is the Month view or week view, is the ability to have a multi day event graphed as one colored bar banner over those respective days. Instead of the event being listed individually for e.g. 3 days straight and repeated as a listing for eac day. It is shown once and the colored bar banner is displayed and graphed over those respective days. Making it one item shown. This cuts down on the clutter of a calendar making it much easier to read in month view or week views.
The color of the banner should reflect the associated color of the calendar. Usually this is a solid filled banner.
