Wow! Very nice solution Jeff! I'm working on an Agenda-function and one of the requirements is to find a particular number of free timeslots for certain Appointment Types (e.g. First Consult needs 3 timeslots, Follow Up just 1 timeslot). Instead of Date and Days I worked your solution out with Time and Timeslots. I won't go into further details, just want to say thanks! 😀
