The Laydrans kept such accurate account of time and astronomy that the Tulehrans adopted their calendar and thereby passed it on to other cultures until it became the dominant calendar in the Tykolm. What follows is a summary of its features.
The Year
One year = 4 seasons = 12 zodiac signs = 36 divisions = 440 days
The Laydran priests reckoned the year from southern spring equinox to following southern spring equinox.
- Ithmox: year
- Ith: day
- Thayx: equinox
- Zaurix: solstice
- Ithmark: an eve, the day before an equinox or solstice
The Seasons
One season = 3 zodiac signs = 9 divisions = 110 days
Seasons are divided into nine divisions.
The equinox or solstice and the next eve are not within any division, giving two feast days per season and eight feast days per year.
Viteer: season
The Zodiac
One zodiac sign = 3 divisions = 36 days
The passage of three signs of the zodiac demarcate a season. As the three moons marked their own individual phases, the Laydrans used the zodiac as a more regular division of the year into twelve months each called a jayg. A jayg is named for the zodiac sign that appeared on the meridian at midnight.
- Jigolz: zodiac sign
- Jigz: the zodiac
- Jayg: a month, twelfth portion or month of a year corresponding to a sign of the zodiac
The Divisions
One division = 12 days
Chivoor: a division of 12 days
