And from what I have heard on science podcasts, the moon is, and has been, and still will be, moving away from the earth. Making the perfect solar eclipse only for a segment of the earth’s history.

I think it’s more wild that not only are big moons rare, ours is literally the same size as the sun from our point of view.
It also makes almost exactly 13 laps for every lap the sun makes.

It honestly makes me feel lucky being born when I was.
We also get to see the after effects of the big bang which won’t be detectable for the majority of the lifetime of our universe.

The big bang part is interesting, because, if humans become successful and manage to somehow make some sort of long-lasting archive that would survive on universal scales, we would be the ancients with old revelations to a potential future species. Able to impart knowledge that would have been undetectable for them, and an ancient map of the stars containing visions of countless other galaxies, and a peek into the very beginnings
Though, realistically, it’s likely that a hypothetical hyper-advanced technological species would have their ways of prodding the true nature of our universe, despite the greater challenges

Child you elaborate on the second point? Why is it only visible in a short period?
Grandwolf319@sh.itjust.works 3 weeks ago
Cause the expansion of the universe. Eventually we won’t be able to see beyond our own galaxy.

A bit late, but the moon does not make “almost exactly 13 laps”. Info from en.wikipedia.org/wiki/Lunar_month
If going by phases of the moon (synodic month), it makes 12.37 laps in a year. Not close to a round number.
If going by position in the sky relative to the stars (sidereal month), it makes 13.37 laps - one more than the former measure, because of Earth’s year cancelling out one month.
There are also other ways to measure it, but none of them get anywhere close to an integer number per year.

It’s almost like someone put it there on purpose 😉

Which is why a 13 month calendar all having 28 days would have made more sense
NeatNit@discuss.tchncs.de 3 weeks ago
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.
mnemonicmonkeys@sh.itjust.works 3 weeks ago
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.”
stray@pawb.social 2 weeks ago
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
ThatGuy46475@lemmy.world 3 weeks ago
12 is an easier number to work with because of how many factors it has
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?
teft@piefed.social 3 weeks ago
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

Get this Roman bullshit outta here
ryedaft@sh.itjust.works 3 weeks ago
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.

Only for pre-decimal society. Nowadays it’s not a problem

Landlords would love it, at least. I personally would hate it, being a renter.
JeromeVancouver@lemmy.ca 3 weeks ago
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

Don’t worry, they ain’t ever gonna replace the Gregorian calendar.

It’s a shame, though. That Jeromian 13 month one sounds like a better fit, whether or not you’re in Vancouver!

13 is a unlucky superstition number.

Only in Western cultures. In East Asia, it’s 4.

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

Didn’t some cultures do that?
