Day

A standardised period of 25 hours which is used to determine the date in the Divine Calendar. On high infrastructure planets, schedules and work-sleep cycles are usually based around the day, with most people waking up around 1. On low-class worlds, and when dealing with farmers, some people will use the local solar day instead.

The Day does not exactly correspond to a solar on any of the 333 worlds; therefore it is assumed that the choice of 25 hours is something to do with the temple ships' navigation algorithms. Certainly, arrivals are always scheduled for an hour which is a prime number.
