I chose quaternary because you have to use decimal for time, weeks, months etc, because it would be a pain in the ass to have to convert everything all the time. So the quaternary system is the "ancient" system they used long ago. But in truth, it's so I don't have to come up with so many names for different numbers haha. I only needed a system that goes to 16 (decimal) so quaternary is a perfect fit in that regard. An example of it in use: the word for rainbow is d'ci'ka. It's a contraction of denci' ("ten-three", or 7) + kaza (color) Thirteen colors. Same process for the word weekend, which is d'ci'mw. Denci' + mw ("one"). 7/1. The 7th and 1st days of the week.
