    13 Fridays the 13th

        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.

            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.

      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.

      Not a calendarologist, but I’m pretty sure lunar calendars were tried and rejected for a reason. Other than the places that still use them for traditional reasons.

      Of course, maybe they just didn’t have the concept of leap days?

        It only comes out to 364 days so you’ll still need to handle that 1.25 extra days in a year otherwise it’ll drift. You could just add December 29th as a special day past Saturday, but then you lose sync with the moon, eg.if New moon was on Sunday the first in the previous year, New moon would be on December 29th instead of on Jan 1st the next year and all new moons would be on the 28th.

        You can keep your calendar in sync with the moon or the sun but not both.

      As someone who has proposed this system myself, I feel the need to point out that the meme is glossing over a couple key points:

      First and foremost, 13*28 is 364 days, so to avoid slippage you’d need an extra day appended to every year, either as part of a month, which breaks symmetry, or on it’s own. You’d also still need leap years.

      And in order for the days of the week to be immutably aligned with dates, these extra days would also have to not be part of any week. Which is a big problem if you want to get anyone who practices an Abrahamic faith on board with the plan.

        What exactly would be so troublesome with having a “special day” outside of the usual week/month cycle? You can still go worship on whatever day of the week applicable to your faith. Just make the last day of the year its own thing. We can call it “New Years Eve” and party together.

          It makes the calendar less than compatible with the commandment to keep the Sabbath by not working on every seventh day.

          Which is not insurmountable in practice (e.g. by keeping a separate ecumenical calendar) but you can bet it would be a significant source of opposition.

    Yay for The Human Calculator Calendar. Boo for not crediting sources. A missed opportunity to replace Jesse’s name with, “Scott.”

    Double boo for not explaining the extra day every year, not to mention leap year. (364 / 28 = 13.)

    Final boo for conflating the real world ~29.5 day imprecise lunar month with the 28 day English common law lunar month.

      Watch out for places (like gyms) that bill biweekly instead of monthly. You may think it lines up with months, but over the course of a year you pay an additional 8.6% more.

        But, if you get paid biweekly and all of your bills are monthly, you basically get an extra paycheck each year.

        No. Base 12 and base 60 are significantly better for things that are commonly divided into halves, thirds, fourths and so on.

        A “day” is 86400 seconds. Changing the length of a second is a non starter, so you’d end up saying a day doesn’t line up with a day night cycle, or something weird like “a day is 8.64 hours long”, which doesn’t feel better than 24.

            We could change the definition of a second, but we’d be changing the si unit of time to mesh up with things that don’t currently have si equivalents. We’d have to redo a significant number of units.
            The meter is defined in terms of the second, which is then used to define the kilogram.
            It’s a base unit that all the others are built on. This wouldn’t be a tweak, it would be rebuilding the metric system. So that there would be ten hours in a day, which we would keep having to tweak because the earths rotation isn’t constant, which is why “day” isn’t an si unit in the first place.

            Yeah, the civilization that decided they like base 60 is long gone, but the reason they liked it is still relevant, which is why we keep using it. Highly composite numbers are really convenient, and ten is a pretty shitty number beyond being the base we often count in.

      13 x 28 = 364

      Make New Years Day it’s own thing, not counted in a month (or just make the new 13th month 29 days long), and continue tacking on leap days to the end of February using the currently established rules.

      The length of the year doesn’t change and no seasonal regression. It has so many fewer exceptions than our current system that you’d wonder how we ever ended up with a 12 month calendar.

          Yes and no. The days would be outside of the normal week (so they would be in a kind of an 8 day week), and they would be holidays to not mess up work schedules in relation to the fixed calendar.

            Many facilities are 24/7 operations that can’t just close for a holiday (ex: hospitals, first responders). It definitely would mess up people’s work schedules.

    I’ve never been a fan of this idea, it doesn’t go far enough and further makes things less symmetric/divisible. I say we use 6-day weeks, 5 weeks per month, 12 months per year, and an inter-calary holiday week of 5-6 days. A six day week means 4 days working, 2 days rest, and that can be staggered more easily/equitably assuming work needs full coverage in a week. We start the new year on the Spring Equinox because it’s generally more pleasant.

    For bonus points, we switch to base-12 (or dozenal) in our numbering system because after the transition it’s a much easier system to deal with as far as division and multiplication is concerned (e.g. 1/4 would be .3 instead of .25, 1/3 is .4 instead of .333…, 1/2 is .6, etc.).

      Though I like the idea a lot, 60 has the great advantage that you can devide it by 2,3,4,5 and 6 which is a very useful property… The real power move would be to use the 60-system for everything… Like the Babylonians did, or so I heared

        It’s useful. But when was the last time you used it? You usually don’t say a twelves or a third or a sixth of an hour, you say 5, 20 or 10 minutes. Half and quarter are available the same in decimal time.

        It’s more a matter of habbit. You know what a second, a minute and an hour are because you had all your life to precisely learn it.

      Hmn…

      You’d need to redefine the derived SI Units, or take new measurements for newly derived units. Newtons, joules, pascals, hertz, coulombs, watts, volts, ohms, farads, siemens, webers, teslas, henrys, becquerels, grays, sieverts, and katals.

      Also not to mention motion and heat.

      You could say there’s a large amount of pressure to not change, or that it’s a high “bar”…

      I hope you smiled, because that is one joke I will not be making again.

        You don’t need to redefine any of them if you don’t change the length of a second though, right? Because the SI unit for time is the second?

        As long as you just change the definition for non-SI units, sure kilometers or miles per hour changes, but that’s not SI, so nobody cares.
