Hours

From The Regnum Animale by Bishop Vitellus of Oaken:

While marking the passage of time is the preoccupation of monks, clerks and sages, the majority of the subjects of the Realm only concern themselves with a rough approximation of the hour.  They divide the segments as follows:

Sunrise = 6 AM to 9 AM
Morrow = 9 AM to 12 PM
Noon = 12 PM to 3 PM
After-Noon = 3 PM to 6 PM
Twilight = 6 PM (or Sunset) to 9 PM
Dusk (Curfew in towns) = 9 PM to 12 AM
Midnight = 12 AM to 3 AM
Witching = 3 AM to 6 AM

Town-dwellers are likely to use the equal hours of the chimes, since there is a chance of a clock tower being nearby or at least a bell ringing the hours.  Other devices include sundials and hourglasses.
