I would prefer 12 months of 30 days each, 6 days per week, then an intercalary week of 5-6 days. 6 days per week means 4 day work week, staggered weekends for those jobs where 24/6 availability would be preferred.

As long as we're wishing for things, I also would like to change our base 10 system for a base 12 system (duodecimal or dozenal). 12 is a superior highly composite number, and it's a bit easier to divide things into thirds, which is more common than fifths.
