Perpetual 3 Month Calendar, formulas only.

I need a perpetual 3 month calendar, preferably made using only formulas. It will be used to keep track of special events, vacation time, etc...

I have assembled a calendar, with the help of youtube, but it has the week starting on Monday. I'd like to have Sunday be on the left instead of the right.

I'm using Excel 2011 for Mac. I don't have a ton on knowledge in this area but I know the basics, like I said, I was able to put together what I have using a tutorial on youtube.

The link to the youtube video is: http://www.youtube.com/watch?v=n-_HXoWmuQE

I've also attached what I have so far. Rows 2,5,32,35,62,65 are hidden.
