It's an incomplete explanation. You have New Year's Day as an intercalary day, essentially January 0th creating a 3 day weekend. It's either considered a Saturday or not assigned a day of the week at all. Leap days are either immediately after or inserted as June 0th the same way.
so it's still full of arbitrary bullshit? "we'll just have a day that doesn't count every year and another day that doesn't count every 4 years except when the year is divisible by 100".
the idea here is that this system is more intuitive than our own, but it's not.
No system can avoid arbitrary bullshit because the earth doesn't go around the sun in an amount of time that's an exact multiple of the time it takes to rotate.
Sounds like why fuck with it then. There's a cost to converting that will be paid only to replace one set of arbitrary bullshit with another set of arbitrary bullshit. You can say you prefer one bullshit to another and no one can dispute you on that, but in the end it's just one set of bullshit vs another and I'm already committed to the current one.
It's probably too difficult to implement now because of computers being entrenched in the existing system. If we were going to implement it, it would have been 100 years ago.
There are pros and cons to every alternative calendar. Just as there are pros and cons to the metric system, hybrid cars, and renewable energy. There is a short term cost to switching to better systems and a long term reward. The earlier we switch, the more reward we reap. Not saying that 13 months is the best alternative but the reasoning of systemic changes hinges on being willing to front costs that we know will be worth it in the long run. Our current one is not causing enough issues and it's upfront cost to switch is too high so we will likely not even seriously consider changing it for a long time. But we can still acknowledge that we should use a better system and that adapting earlier will only benefit us in the long run.
What is actually better about it? It's a bit more intuitive except for where it isn't, and it forces people to develop an entirely new concept of the 0th of January (and occasionally 0th of June). What do we do on the 0th? How does that fit into things that cycle with a period of 1 month? It breaks the idea that a 1 month period is equivalent to a 4 week period, which is supposed to be the entirety of why we're doing this in the first place.
The problem is that the earth doesn't orbit around the sun in a whole # of days. A sidereal year is 365 days, 6 hours, 9 minutes and 10 seconds, or 365.256 days.
Likewise, the moon doesn't orbit the earth in a perfect whole # of days either. The moon takes 27.3 days.
Since we cannot change the orbital period or rotation of the earth, we are kind of stuck with accommodating the "arbitrary bullshit" of astrophysical bodies.
then, as I said to the last person who pointed this out even though my math implies that I already know it, why this new bullshit instead of the bullshit we've already implemented?
