Berikel Hemisphere

A bit crudely drawn, but this is a rough picture of the Berikel, or "New World" hemisphere of Xhilr, with the axis of rotation drawn through it for reference.

Note that the choice of North and South could be seen as arbitrary, but I am keeping the translation spin-congruent with our own Earth and solar system. North is the direction you would face when putting the rising sun on your right in the morning.

Those are ice caps at the poles, of course.

 The opposite "Old World" hemisphere is where most of secular history records the rise of civilization.

Xhilr

(Very incomplete introduction)

Xhilr is a planet with two moons.

The smaller, nether moon orbits their world in just under seven and one eighth of their days, giving about forty-nine and a half fast-lunar weeks a year.

The larger, hinter moon orbits in about twenty-eight and seven eighths days, giving about twelve and one fifth slow-lunar months each year.

The exact fractional number of days in a year is very close to 

352 485/686 (about 352.706997_ten)

yielding a complicated series of skip and leap years in a seven year cycle, a 98 year cycle, and a 343 year cycle. But on Xhilr, the most commonly used numeric base is hexadecimal. So that's actually

160 1E5/2AE_sixteen (about 160.B4FDC2_sixteen)

The most common clock has sixteen (long) hours in a day.

In most countries, decimal is only for children to use their fingers to count, or for mathematicians to amuse themselves with. Non-repeating fractions are a curiosity

The most common clock uses hexadecimal time -- hour 0:00 (or 10:00_sixteen) is midnight, and 8:00 is noon. The short minute before midnight is F:FF_sixteen.

There are C_sixteen months in a year with the following number of days, each:
