Ock Cycle

The close moon of Didome has a orbital period of about 16 Earth hours and many culture use this amount of time as an equivalent to an Earth day. Culture that do this generally sleep for 5 hours and spend the rest of the time on work and chores. Since Didome has not experienced an industrial revolution people generally don't need any more fine grained sense of time. Alternatively, some cultures use orbits of Ock‌ to define their day. These culture sleep for around 8 hours and then have a 2 hour halfway through the second cycle.
