The Chaos Eclipse
Astronomy and Timekeeping
Instead of one moon orbiting once every twenty-seven days, there are two: compared to ours (in absolute size, not appearance; the two moons appear to be about the same size from the surface of Alutiria,) there is a moon (Aiosomenot or Coppermoon) orbiting Alutiria once every seven days; and a satellite about the size of our Moon (Argomenot or Silvermoon) orbiting every 31 days. Aiosomenot is a ruddy moon with some volcanic activity visible to the unaided eye; Argemenot is a bright gray, almost white, nearly featureless moon. There are legends of a third moon (Yelðomenot or Goldmoon,) which is said to join Coppermoon and Silvermoon once in an age; some claim to see Goldmoon wandering the skies, almost beyond detection; most others claim that these legends are nonsense.
Alutiria orbits its sun (Sawelos) once every 401 days (this due to its faster rotation than Earth; our days are longer than theirs.) This has made it possible for solar calendars to have four hundred days, with one epagomenal day (that is, outside of the calendar altogether, and often called Meisteðey or Missedday, and Octoðey or Eighthday in seven-day weekly calendars.)
