The Gwaith, being the first to create a calendar, standardized time in Etendya. Observing the world moving through the stars around Anw, and being circled by Inu, the charted the progress.
Each week is five days, named following the elements. Most use the Gwaith words for this (Lindaur, Nenaur, Caeur, Erynaur, and Naure), though human lands they are usually called by the common names of Lyfday, Waeday, Earday, Holtday, and Fyrday. These cycle continuously and are, for most people in the city, all of the calendar they need.
Structure of a Month
Every month begins at dawn following the new moon, and numbers either 29 or 30 days. Months are named based the greater petal which first occurs during the month (see Structure of a Year). Months generally occur in the order of Ring, Ethuil, Cuivea, Norui, Laer, Yavien, Ure, Lasbelin, Nimbiren, Nicunite, Niquis, and Loss.
Structure of a Year
A year begins at the dawn following the new moon following the longest night of the year. As the Etendya it goes through twenty equally spaced solar locations, called petals, which in turn are alternated into greater and lesser. As these are based on the sun, the do not stay on given calendar days. The naming of these are in part based on seasonal events at the Imperial Capitol, and can been seen with a certain degree of irony in other parts of the Empire.
Most years consist of thirteen lunar months, but every fourth year only counts twelve. As months are named after the great petal contained within it (and there are only twelve greater petals), if no great petal is in a month is named Alagos, or Fallen.
Naming of a Year
The years follow through cycles of the sixty-four Universal Aspects and eighty-one Heavenly Creatures. A year is named The Year of the Aspect Animal. For example, the current year, 3067NG, is the Year of the Restored Owl.
