I would like 12 equal months with 30 days each followed by a 5 or 6 day period of celebration and reflection between the prior and next year. Each month could also then be made of 5 six day weeks (or 6 five day weeks). Making the celebration between "years" a "week long thing.
Or how about starting the year on the equinox or the solstice?
I’d prefer a more purely metric calendar if we are going to the effort. Stardate system I suppose
a 10 month calendar with 6 week of 6 days would work for me as well. If July and August were dropped, it would allow some of the original meaning of SEPTEMber, OCTOber, NOVEMber, DECEMber to ring true again. I would propose 4 days of work and two days of leisure per six day week :-)
Some print shops (commercial printers) would contain joke calendars that showed each week with two Fridays. Thus making it more likely for jobs to be "completed before the weekend".
