Archaeologists have found that a straight stone causeway on Mount Ttlaloc in Mexico aligns with the rising sun on February 23rd/24th.

The long causeway at the summit strongly suggests that the ceremonial structure was used as a solar landmark, aligning very precisely with the rising sun on February 23 to 24 and October 19 to 20. The same alignment is found if Mount Tlaloc is viewed from Mount Tepeyac, a holy site whose use as a sacred mount and solar observation post preceded the establishment of the Mexica civilization in the Basin.”

The mountain was worshiped by the Aztecs, who associated it with the rain god Tlaloc as one of his earthly dwelling places, called Tlalocan.

Extravagant ceremonies, plentiful offerings, and the lives of young Mesoamericans were all offered to Tlaloc in order to appease him at the beginning of the rain season.

The researchers state in their paper: “Many early codices seem to validate the working hypothesis that Mount Tlaloc was instrumental in the establishment of the date of the Basin’s new year and in the adjustments necessary to keep the agricultural calendar in synchrony with the solar year.”

svsss calendar wahoo.

[dead-generations]

learning the mesoamerican calendar like

every other calendar system is garbage. this is genius. this solves almost every problem with every calendar system ever. Why the fuck wouldn't you use a double calendar system? It's even intuitive once you have it in front of you. It lets you track dates across long periods of time with incredible precision with very little upfront information. You wouldn't need to know someone's birth year to know how old they were, just the date for their birth. no wonder many used birth dates to name children.

So if hasemura day is 4/14, and hayashigeki day is 5/16, and watazaki day is 9/15, and hamatsuno day is 10/11, what's tsunozaki day?

I might actually have to fucking kill the 3 moons thing in my setting. I might have to do it. Like I'm willing to just completely ignore how having 3 large satellites would absolutely change conditions from 1:1 earthlike in major ways, but I can't(??? maybe) have the moons be visible in different phases in any given day.

Like:

Per this highly professional diagram, if the 3 moons are each in these circled (relative) positions to the sun on their respective orbits, an earth viewer would see each 'rise' and 'set' over the course of a given day in 3 separate phases right?? This is definitely elementary school basic but my brain is fucking fried right now so bear with me.

On one hand (still wholly ignoring planetary physics) this could be an opportunity for more complex worldbuilding in ways that would be fun for me (special significance when all 3 are visible in the same phase, loads of implications for astrology systems, etc) but on the other hand the lunisolar calendar system I painstakingly figured out and is important to the story would be in fucking shambles because I didn't think of this issue until now somehow.

listen to me. no listen. nothing humbles you like learning a new calendar system. especially one that works on a completely different and arbitrary system to the one you are used to. does it make sense? sure, if you're fucking good at visualising calendars that work by counting by either 6 or 12. tolkien please i am gonna haunt your ass so hard why did you make so many different calender systems.

also my poor blorbo is having a very bad time :( she went from "omg diary i think i have a crush??" to "mother why is there fire over the mountains?"

also i don't think i like how i've formatted the dates??? i mean it as in "the 2nd valaday of winter" but I've written it as "winter, valaday 2nd" so maybe i'll redo that idk

originally for my thesis i was gonna like, focus on each aspect of the prague astronomical clock like its history, its function, and its design separately - but even other than this scope was way too big for me, the design IS the function. like, obviously, It's A Clock........ but! the reason the face plate has multiple colors is because they represent the time of day. the blue field is day, the orange is dawn and dusk, and the black circle is night. the placement of the sun symbol indicates the placement in the day cycle. I Know I Know It's A Clock Of Course It Does That but it's different to how we're used to reading clocks in this day and age.

anyway it reminded me of first year of watchmaker school, when we were learning to blue steel, a process that gives steel a specific material quality and also turns it blue. you might see high end watched that have blue hands and blue screws, for example, and it's not Just for the aesthetic, it's a sign of quality, but it has BECOME a preferred aesthetic BECAUSE of the quality. my teacher asked me if i, as a former art history student, knew whether it was common for something to Become Beautiful because it was a Desired Quality. i didn't have a good answer at the time but i have clearly not stopped thinking about it. i think it's a kind of survivorship bias - something can be the most aesthetically pleasing and beautiful but it won't really matter if it crumbles to dust within a couple years and there's no way for future generations to appreciate it. it doesn't make it less beautiful, only that we have no clue it ever existed. so in that sense, the beauty of functionality persists

Key astrological changes of 2025 in order of relevance

In my opinion, these are the most noteworthy astrological movements of the year 2025:

Pluto in Aquarius

Neptune in Aries

Uranus in Gemini

Saturn in Aries

Mars retrograde

Lunar Nodes in Pisces and Virgo

Venus retrograde

Jupiter in Cancer

But why?

Because most of these changes don’t occur on a yearly frequency. Therefore, when they DO happen, and especially if they happen together, that’s a big year.

Don’t believe me? Check this out:

Pluto changes signs every 12 to 30 years.

Neptune changes signs every 14 years.

Uranus changes signs every 7 years.

Saturn changes signs every 3 years.

Mars retrogrades every two years for 9 % of its cycle.

The Lunar Nodes change signs approximately every year and a half.

Venus retrogrades every year and a half for 7 % of its cycle.

Jupiter changes signs once per year.

See now why I consider 2025 to be a big year? So many changes happening in the same span of time is nothing short of extraordinary.
