Why not do separate H1, H2 and H3 calendars?
Publishing 3 different calendars would require 3 times the investment in both time and money. It costs thousands of dollars and takes hundreds of man-hours to publish one calendar. It would simply be unwise to invest all it would take to publish 2 additional calendars with absolutely no indication that they would sell and the additional investment would be worthwhile. Also, our licensing agreement may not permit this.
