@jmorga106, @phantasico, et al (that Latin BTW)
I am very familiar with the 'rule set' data, time/date/calendar software code ('black box' engine), and Internet standards for calendar data (iCal, RFC 5545/5546. etc.), and even assisted in their 'improvement' back in 2009-10 (they went backwards). If we do find a way forward, I can assist greatly.
My issue for Facer (Creator) is how we can 'add to the platform', due to limitations around syntax, logic expressions, and user-defined variables, etc.
