A new time format for the years

Time to use yet another standard that will my break software! A while back I stumbled upon the Holocene Calendar, which was also popularized by Kurzgezagt:

The Holocene correlates with the last maximum axial tilt towards the Sun of the Earth’s obliquity. The Holocene corresponds with the rapid proliferation, growth, and impacts of the human species worldwide, including all of its written history, technological revolutions, development of major civilizations, and overall significant transition towards urban living in the present.

It starts counting years roughly after the ice age, after the adorable character Scrat finally collects and burries the acorn. It is quite easy, just add 10,000 years to the current commonly used year format. Quite a clever choice, because it is distinct enough to recognize without having to do any difficult conversion. Just write a one in front, and perhaps a comma to denote thousands for readability.

Now ofcourse it is not recommended to just change existing data to it. I see it as just a unit, a display option like Celcius and Fahrenheit. On this website, I have changed the year format on the post index page. It took a staggering one line of code and voilà, now it is fancy.

Existing urls will be kept, and so will the semantic datetime attribute.
