        This.

        And also, it should still be 12 months, just 4 months (December, January, June and July) should have 5 weeks while the other months have 4 weeks.

        The last weeks of December and June and the first weeks of January and July then form a special kind of “half months”, where you get a half month salary and pay a half month rent, etc. Christmas and New Years nicely fit in the Jan/Dec two week holiday, which would be 15 days instead of 14.

        In a leap year, the June/July half month would be 15 days instead of 14

        This way each season/quarter is still equal to 3 months with 13 weeks. And a half year is 6 months with 26 weeks.

        Someone mentioned seasonal regression, this solution should solve that.

        And the irony of this all… This is very close to how our current calendar started before Caesars fucked it up.

          But they you still have irregularities. Easier to just add Undecimber to the calendar.

            You would then lose the ability to divide the year into pieces, since 13 is prime.

            No half-yearly, quarterly or bi-monthly rhythm.

              Our quarters don’t follow the actual half anyway, with the solstice and equinox not matching up with the months.

              The divide is easy, and can be marked on the calendar like a holiday.

              • 3 months and a week
              • 6 months and two weeks
              • 9 months and three weeks
              • New years (or day before or after, take your pick)

              Much more convenient than making the whole calendar inconsistent.

              Those divisions are already skewed in a 12 month calendar though because the number of days is not similarly divisible:

              Half year (6 months)

              1st half: 181 days (182 for leap years)

              2nd half: 184 days

              Quarter year (3 months)

              1st quarter: 90 days (91 for leap years)

              2nd quarter: 91 days

              3rd quarter: 92 days

              4th quarter: 92 days

              A leap year has 366 days which is evenly divisible by 2 and yet even then a “half year” at the monthly level doesn’t contain half the days of the year. Having uneven yearly divisions in a 13 month calendar would not be a new problem.

      Have a “liminal day” that serves as New Year’s Day, and then every leap year put the extra day as the last day of the leap year after the last month.

      The big trouble is that there isn’t a subdivision between the month and the year, 13 is prime, there isn’t a whole number division of months that can be used to mark say a fiscal quarter for example.

      So I say instead of a 13th month, split those 4 weeks to be an extra week at the end of every 3rd month, so March, June, September, and December would all have 35 days instead of 28.

      Kinda what Caesar was going for originally too, having the months alternate between 30 and 31 days, but he fucked it up because Romans were superstitious about February for whatever reason.

      Every new years day and leap day exists as its own thing outside of any particular month. So every year we get a full new year holiday and about every four years it’s a full blown 2 day event. It doesn’t need to even be a named day of the week or part of a named month. It can just be it’s own thing. We can number it as the 0 month if it makes you feel better and to help sorting dates. If we’re feeling sentimental, maybe we can call it Friday the 13th because those won’t be a thing anymore otherwise.

        Each year, the moon phase would shift one day (and an additional every four years for a leap day), then sync with that day for the next year. That sounds much better than what we have now.

          Eh, having a lunar calendar is overrated IMO. Especially since going by lunar phase is actually an inaccurate time keeper for seasons and the like.
