  It makes 12 months because the lap the Earth makes is deducted from the 13 the moon makes, so effectively it makes 12 cycles around the Earth.

    You don’t know what you’re talking about

    13x28=364. The moon makes 14 sidereal orbits, not 13. The reaaon the year is split into 12 months is a combination of Roman dipshittery and the fact that 12 is divisible by 2, 3, 4, and 6. The number of factors of 12 made 12 and 60 way easier to work with for societies that hadn’t invented the decimal point yet.

      Then please explain how the Hebrew calendar, and all other lunisolar calendars (calendars which follow both the solar year and the lunar cycle) have 12 months most years? en.wikipedia.org/wiki/Lunisolar_calendar

      “The majority of years have twelve months but every second or third year is an embolismic year, which adds a thirteenth intercalary, embolismic, or leap month.”

        Not who you asked, but after looking into it it’s because the moon takes about 29.5 days to complete a full cycle of phases (one synodic month), giving it time to do so roughly 12 times per year.

        I can’t quite wrap my head around it, but I think the explanation for why sidereal and synodic months differ lines up with your initial explanation. Because we’re also moving, the moon has to move further to achieve the visual change of moon phases.

      Can you provide a source for 14 orbits? Everything in my search results says 13 and some change.

      Wikipedia says one sidereal month is 27.321661 days and a sidereal year is 365.256 days.

      365.256/27.321661 ≈ 13.37

        a sidereal year is 365.256 days.

        No. A sidereal year is 366.24 days.

        And 11 days isn’t “and some change”

  12 is an easier number to work with because of how many factors it has

  source

  • nialv7@lemmy.world ⁨3⁩ ⁨weeks⁩ ago

    hmm, how about 12 months each with 30 days, plus 5 days every year that’s not part of any month?

      days every year that’s not part of any month

      Those are called intercalary months. They had them in the ancient egyptian calendar and were usually used for rest and religious ceremonies.

      Just add a leap month every six years

      source

      • ReluctantMuskrat@lemmy.world ⁨3⁩ ⁨weeks⁩ ago

        While a novel idea, a leap month would throw the concept seasons and therefore agriculture off significantly. Relatively predictable seasons and being able to track our place in it with calendars was a great help to agrarian communities, helping them know when to plant and harvest most effectively.

      13*28=364 so even 13 months and 28 days doesn’t work.

      If we had 28 days in a month then the week needs to be something other than 7 days. Three out of four times February / March fucks me over by having the same weekday/ day of the month.

    Haha great point. I never thought of that

  • BussyCat@lemmy.world ⁨3⁩ ⁨weeks⁩ ago

    Your rent right now can be thought of as a large payment split into 12 equal pieces (even though months aren’t actually equal) and your rent payment is just 1/12 of that. If there were 13 months it would just be split into 1/13 so each months payments would be slightly smaller to be the same total

    If we transitioned it would take years and for at least some amount of time of overlap they would show both prices so it would be much harder for them to just jack up the price like they would prefer to do

      In China, it’s 8 due to the number sounding like the Mandarin word for death

      source

      • TheRealKuni@piefed.social ⁨2⁩ ⁨weeks⁩ ago

        In my understanding, 4 sounds like the word for death and 8 sounds like the word for wealth, so 8 is considered lucky.

        But I don’t speak any version of Chinese, and could very well be wrong.
