Setting starting day on a custom calendar?

[nosut]

Hey guys trying to figure out how to properly create a custom calendar. I have managed to create a simple calendar for our campaign however each time a month changes it starts over on the first day of the week(IE all months start on Sunday) instead of naturally going to the next(IE January ends on friday so february 1st is saturday) . My calendar has exactly 57 weeks so every year each day will be on the same date. Is there an easy way to set that starting day for each month?

You need to create a custom function via an extension that calculates the starting day of each month correctly.

Damn. Was hoping there was an easier way to just "set" the month start. I tryed creating an .ext off of a sample like I did with the .mod but had far less luck figuring it out.
