An update on this.

I thought I had figured out how to do this. I set up a total of three separate shared schedules (not bothering with leap year at this point),

1 - on the 30th day of April, June, September & November

2 - on the 31st day of January, March, May, July, August, October & December

3 - on the 28th day of February

However this doesn't work as I expected because I'm still getting schedules executed on the 30th day of the month in months that have 31 days.

Again, any insight would be helpful. I can't believe that I'm the only one that's trying to figure this out.
