P.S.:
SethO,
Here is a calendar set up. Easy to move the first day of the month while keeping the Sundays in a different color.
It is all based on a point selection. This selection needs only a starting point, and the Clone amount will fill the following.
The second file uses Fields for the starting point, to create an even more comfortable way to set things up.
I chose a 6 by 5 segment plane, as 6 segments produce 7 points.
I hope that will allow for a simple process and leaves all options for MoGraph open.
