I've often dreamed of and revisited this idea. I first started thinking of it seriously when I realized I was paying the same rent in February as in January despite a significantly shorter-than-mean (30.4375) month...!
My ideal year is 12 months, each 5 weeks long, each week 6 days long. At the summer solstice, 3 intercalary days (bank holidays), at the winter solstice, 2 or 3 intercalary days depending on leap year.
They're cool people but like it doesn't stop the world from imploding. Most of all of our code is full of trivial bugs and edge cases and most people don't mind too much. Certainly no one cares about leap seconds, they hardly even notice DST or leap days
