Rystonian standard time, more commonly known as RST is UTC-7. Also known as mountain time, RST is the official time everywhere in Rystonia.
Nuvan is the official temperature system for Rystonia, used in official media and documentation. The name of it has no historical meaning or any meaning at all. Freezing is -20°N and boiling is 180°N, with 200°N between them. This means that:
Every 5°C is 10°N.
Every 9°F is 10°N.
60°N: REALLY Hot (40 C, 104°F)
40°N: Hot (30°C, 86°F)
20°N: Comfortable Room Temp (20°C, 68°F)
0°N: Chilly (10°C, 50°F)
-20°N: Water Freezes (0°C, 32 F)
-40°N: Cold-ish (-10°C, 14°F)
-60°N: Cold (-20°C, -4° F)
-80°N: REALLY Cold (-30°C, -22° F)
When Nuvan was first being made, the boiling point of water was 132°N and the freezing point was -32°N.
Using this you can convert Fahrenheit and Celsius to Nuvan, and Nuvan to Celsius and Fahrenheit.
As of July 2026, Rystonia may be soon experimenting with using a Base-12 measurement/counting system in official media, math documents, and written documents. This makes it easier to divide up since 12 is fully divisible by 1, 2, 3, 4, 6, and 12. Fractions like 1/3 will be 0.4 instead of 0.3 repeating, or 1/6 will be 0.2 instead of 0.6 repeating.
0, 1, 2, 3, 4, 5, 6, 7, 8, 9, X, Ɛ, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 1X, 1Ɛ, 20.
The names of the numbers will be the same, except for Eleven being Elve. 11 is Unteen, 12 is twoteen, 1X is tenteen, 1Ɛ is Elfteen, and 20 is twenty like normal.
This also means that there are two new decades (called dodecades in this counting system):
X0: Tenty
Ɛ0: Eleventy
100 will be Dohendred and 1,000 will be Dothousand.
One issue with this is that we only have 5 fingers on one hand, and 10 fingers on both hands. That will make counting to 12 harder, but we have a solution.
When counting with two hands, start using your index finger or thumb. When you run out of fingers, open them to represent 11 and close them again to represent 12.
If you need to do it with one hand, you can start with your index finger or thumb but after 5, curl each finger one by one. Then when you reach 11 you open your hand up, and when you reach 12 you close your fist and start over. You can also use your thumb to count the spaces in your fingers, which counts to 12 and you can put one finger up on your other hand when you restart too. This is how some other cultures do it that use Base-12.
