How the Third Horizon reckons time, p.248:
Cycle: 1 Kuan year, 336 Kuan days
Triad: a “season”, more or less. 3/cycle. 1 extra day between each.
Segment: 1 “month” more or less. Note that Kua has no moon so there is no concept of a lunar month. 37 Kuan days. 9/cycle.
“Each segment ends with an extended rest period.” Hmmm... When, I wonder? Maybe that’s just what Third Horizon employers put on their recruiting material....
Day (Kuan): 26 hours, p.287
Watch: 6 hours (morning, day, evening and night). Wait, this doesn’t work out. There are 2 hours leftover. Perhaps a watch is 6.5 hours. Someone please ask their character and let us know.
Hour: Presumably one real life hour
Minute: See hour..
Turn: 10-20 seconds. Obviously denizens of the Third Horizon don’t know that we decide their fates using this time metric. Shhhh! Don’t tell them!
Second: See minute..
Notice something? There is no “week.” On IRL Earth, the origin of the concept of a week is tightly related to the concept of the lunar month, which doesn’t exist on Kua. No lunar months means no weeks either. Makes perfect sense.
Then the proverbial “other shoe” drops....
The word “week” appears 14 times in the core rulebook, including in actual rules (not just flavor-text). None of them explain what it is. 7 day weeks don’t work out neatly because the next largest unit of time is the 37 day long Segment, but 7 day weeks don’t work out neatly in the IRL Gregorian calendar either and we use it anyway. Let’s see... doesn’t divide evenly for Triads, hmmm. Ha! It works out for Cycles! There would be exactly 48 weeks in a Cycle.
How long is a “week” in The Third Horizon? I guess it’s 7 days.
