What is the axial tilt of Chriirah? And how long is a Chriirah Day/Year?

I have my own personal theory for how long a Chriirah year and day could be. Seeing as Chriirah is about the the same radius as Venus, or about 0.95% of Earth's radius, the time it would take for Chriirah to make a full rotation would be approximately 0.95% of Earths, or about 22 hours and 48 minutes.

Then I tried figuring out what Chriirah's solar year could be. While we do not currently know how far away Chriirah is from its star, Alex Ries said it's orbiting a G-type star like Earth's, meaning it's distance from its star must be pretty similar. Considering the drastic effects of climate change on Chriirah, it could also be assumed the planet is slightly closer to its star than Earth, but still in the habitable zone. I used 336 earth days to represent 1 Chriirah Year.

Now, this is where it gets complicated. I tried figuring out how many Chriirah days are in 1 Chriirah year. 1 Earth day equals 1.05 Chriirah days, so 336 earth days would equal 352.8 chrirah days. Obviously this is not a whole number, but Earth shares a similar problem having 365.25 days. The Birrin could have a leap year every five years. A normal year would be 352 chriirah days, while a leap year would be 356 chriirah days.

Interestingly, 352 is divisible by 11, giving us 32. A Chriirah year could consist of 11 months, 32 days each. The leap year could have a twelth month consisting of only 4 days, known as a intercalary month (en.wikipedia.org/wiki/Intercal…)

Since each month is equal in length, they can be divided equally, too. 1 month of 32 days can be divided in 4 weeks consisting of eight days each.

Here are the conversion formulas:
1 Earth day = 1.05 Chriirah days
1 Chriirah day= 0.95 Earth day


Also I was writing this, I realized the Birrin have 3 fingers on each hand. Humans use a Base 10 numeral system because at a young age you learn to count using your fingers. The Birrin could use a Base 6 system, counting 1,2,3,4,5 and then 6 being '10.' This video does a much better video at explaining what I am talking about: www.youtube.com/watch?v=U6xJfP…

Using the Base 6 system, a Chriirah decade would be 6 chriirah years, a century 36 chriirah years, a millennium 216 chriirah years, and a myriaannum 1296 chriirah years.

What map projection is this?  The grid suggests a plate carrée, but I don’t quite get that impression by comparing it with the globe at right, so I don’t want to jump to conclusions.

How many nations exist politically? I assume the dominant ones come from the north and south, and good ol'fashioned mad maxery happening in the kiln regions, probably under political and economic dominance from polar nations.
