I've always lived in 4 seasons land and never thought about how wild it is that some fairly tropical ancient societies tracked the solstices and equinoxes… and apparently thought the Aztecs and Sumerians were tropical because the bias of habitable land towards the northern hemisphere continues to fuck with my mind as to just how intense it is. What the fuck do you mean only 4 countries even reach the southern temperate zone, and Australia only barely so. All of Europe, most of the US, and like half of China and the middle east are in the northern one…
Yeah, the subtropics screw with my sense of temperature, weather, and time. The fact that 40% of people live in the tropics does dampen making global holidays of the solar events that are so significant to those of us temperate zone folks and are pretty noticeable to the semitropical folks even more than the fact that the Argentinians, South Africans, and Kiwis are celebrating the opposite ones of most temperate zoners. Or the fact that the Brazilians, Congolese, and Indonesians will be celebrating both in different parts of their country.
But yeah, I still do think it's worth it because it celebrates the earth and its cycles and you can put local flair on it however you want to celebrate the way the global cycles apply to your area. And looking it up, two of the half season holidays correspond within a day to the start of the Wet/Dry seasons, so all the more reason to have all 8
