Year

One Eridian year is approximately 42 Earth days. There are 197 Eridians days in a year, written 525 in base 6. This is a prime number, which is kind of suboptimal for a year because you'd want it to be more divisible. My headcanon is Eridians discovered their orbital period kind of late because of the difficulties in making direct observations. They now use their actual orbital period as a planetary standard time measure, but traditionally marked years off of periodic natural phenomena, or by tracking recurring changes in their planet's magnetic field.

I was trying to calculate how old Rocky is and how long he was alone in space but to be frank I keep getting different answers when I check my math and I think I'm fucking something up so I'll come back and add that info here later for future reference when I have time to work on it properly.

Day

There are 6 orrs in a day, or 5.1 hours/306 min. Eridians sleep somewhere between 4 and 14 orrs at a time. They are awake and active for multiple days at a time, but a work shift or school day usually take a full day, followed by a 'rest' day for eating, hygiene, and other activities. The day is based off of temperature fluctuations, rather than directly observable light, with 6 orrs of heating and 6 orrs of cooling, with the cooling period being ideal for rest. There's no axial tilt, so light/heat is essentially the same all over the globe. In early civilizations, there would be 10 days of work/rest (5 work periods and 5 rest periods), followed by a market day on the 6th heat period and a rest period, then the cycle would reset. This traditional 12 day "week" is still commonly used in many work places and schools. Some workers have to work inverted or swing schedules, resting during the hot periods, but like night shift workers on Earth often struggle with metabolic disruption and find the schedule stressful in the long run. They often have longer and more frequent dormant/sleep periods as a result, while a healthy Eridian has a little control over when they sleep and can prepare a nest for a rest period with companions and will sleep for 4-6 orrs.

Orr

There are about 51 minutes in an orr. It has the same practical meaning as an hour on Earth.

Tik

There are about 8.5 minutes in a tik, and 6 tiks in an orr. It has the same cultural connotation as "ten minutes", and is often used to estimate tasks. When Rocky is making chain, he might estimate that he can complete 100/216 links a tik, or that would take him one tik to fabricate a small xenonite model.

Mim

There are about 85 seconds in a mim, 6 mims in a tik, and 36 mims in an orr. It has the same practical meaning as one minute.

Bip

There are 14.166 seconds in a bip. It has the connotation of "ten seconds" or "a moment", and is often used to suggest the amount of time to complete a short action or task. If you're working in a quarry, it might take a bip to set up a stone, break it, and move the pieces into a container. Or if you're digging a hole, it would take a bip to dig the shovel into the dirt, scoop, and dump. One bite of food can be eaten in a bip. Etc.
