If we are making up calendars why don't we have 13 months of 28 days leading to 364 days. This means every month has 4 weeks of 7 days and an extra day a year which we can make a celebration day that doesn't land on a day of the week. So every year every day lands on the same day of the week and an extra day (or two on leap years) that aren't part of the typical week
wow, until becoming attached to the current calander in my youth i had always believed this would be more efficient, you really gave me a great reason for the Gregorian
I've been saying this exact thing for years, but good luck selling the idea to people who are either superstitious idiots, hate prime numbers, or both. "Oh noes, we can't divide 13 into halves and quarters whatever shall we do?" Might as well keep using the stupid thing we've always used. Never mind that I'm 45 and still haven't bothered to learn which months have 31 days vs. 30 days. Because I know how to look at a calender/phone.
What about 10 months of 36 days each. Change weeks to 6 days with 2 day weekends. Equinoxes, solstices, new years, and leap years get their own days outside of months and weeks.
