I hope questions are allowed here. I am curios if there is a different sort of scientific calendar which does not use the birth of Jesus as a reference like AD and BC. For example Kurzgesagt’s calendars use the the current year plus 10000 as this represents the human better or something like that.
Would there be a way to do this more accurately? How could we, in a scientific correct way, define a reference from where we are counting years?
Also I have read about the idea of having 13 months instead of 12 would be “nice” because then we could have a even distributed amount of days per month.
Are there already ideas for this? What would you recommend to read?
Unix time. Zero is midnight UTC on 1 January 1970.
often use it as my birthday to crash poorly written scripts. zeros are fun to inject
Birth of Jesus isn’t even accurate. Best guess is that, if it happened at all, which is up for debate, it was around 4 BC.
The YouTube Channel Kurzgesagt has proposed a calendar based on the 'Human Era’ (HE) instead of before/after christ format.
It’s based on the first monument of large-scale human cooperation (building a temple in modern-day turkey) and is quite elegant in my opinion. It ‘simply’ adds 10.000 years to the calendar we’re all already used to. :)
Kiugessgt was good before they started listing all the ways humanity is doomed. I just can’t watch it anymore.
My ideal is dropping the month altogether for 13 week Quarters with the last day being an intercalary outside the week and same for leap days.
If you wanna avoid huge date numbers, break it down further by weeks, so for example my BDay this year would be 3.10.3, third day of the tenth week of the third quarter.
As for year counting, I like Era of History for the current era, dating to the invention of writing, Era of Legend, dating back 100k years to the earliest date that stories we have preserved now would have to date back to, Era of Evolution, which dates back to the development of Life on Earth, Era of Stars which dates back to the birth of the first Stars in the Universe, and finally the Era of Energy, in which the universe was so superheated that large cosmic structures were physically impossible, dating to the Big Bang.
Today’s Date is 3.8.1; 5,224 EoH
You can also make a quarter align with the seasons, so you can just call it spring, winter, …
You can also keep 12 months and make them 30 days each, and add an equinox day in between the seasons. Winter solstice has new year tacked to it and in a leap year summer solstice is two days with the leap year. Keeps it all nicely aligned with the sun.
If you really want you can do weeks of 6 days so each month comes down to exactly 5 weeks of 6 days so the calendar is perfectly reusable each year.
Doesn’t the Southern hemisphere experience winter when we have summer?
Yeah but with the 7 day week you only have 1 or two intercalaries to figure out
6 day weeks leave you with five or six, and having almost a week on average of extra days to make work feels like too much of a nuisance just to be able to keep a unit of measure that doesn’t really serve any actual specificity that you can’t get with the Q-W-D format date.
Barycentric Dynamical Time is one example of an astronomical time standard used in orbital dynamics models requiring consistency across billions of years and relativistic reference frames.
Maybe a calendar that starts with the creation of the Earth (approx 4 billion years ago) as it’s starting point?
Like that joke about the T-Rex that’s 65 million and 10 years old.
Holocene Calendar is the one used by those Kurzgesagt calendars.
See the Julian day.
Very interesting. Thank you!
I don’t know of any books I can recommend, but I’d definitely be down for 13 months with one being short. We could do 12 months of 30 days each plus a 13th month of 5 (or on leap years 6) days.
As far as anything that exists today, there is the Unix Timestamp which is defined as the number of seconds since (the entirely arbitrary time of) midnight January 1st 1970 UTC. Of course, “1970” only makes sense in the context of the Gregorian calendar which still has to do with the birth of Jesus. So, it’s not exactly what you’re looking for. But maybe it’s at least more removed from “the birth of Jesus” than the Gregorian calendar we all generally use.
I guess if you’re interested in this stuff, you might be interested in learning about ISO-8601, a standard way of representing dates/times in text. And also the concept of “leap seconds” and things like Leap Smearing.
There’s also a great short story about someone trying to explain to an alien with no familarity with earth how our calendar works, but I’m having trouble finding it now. I’ll edit this post with a link if I can find it.
Why would you have 30 days in those months? I’m a fan of having exactly 4 weeks each month (28 days), across 13 months. Then every month is the same. If the 1st is on a Monday, then the 1st of every month will always be a Monday. You just need to add a leap week in every now and again.
now could always be zero with future positive and past negative. serious refactoring
That is one interesting approach. I like it.
The one I am looking for counts the remaining days to total nuclear annihilation.
Chinese calendar?
Who is this Jesus fellow? Everyone knows that today is a.d. viii Id. Aug. anno MMDCCLXXVII A.U.C.
CE and BCE. Same thing different name. shrug
