The Elfin, or Lornian, calendar is lunar,
that is, based upon the cycles of the moon. Each season lasts for
exactly 81 days, which is comprised of three total lunar cycles (three
full and three new moons.) A new season always begins on the night
of a full moon. The elfin year lasts for four seasons, and therefore
324 days.

Elves do not concern themselves with the naming of days or weeks (though they do have a rough approximation of a week which lasts for nine days - 1/3 of a lunar cycle.) If one must be specific about a certain day, it is simply identified as the nth day of a certain season. For example, a day in mid-spring would be referred to as the 42nd day of Novochassé. Elves, Lornian citizens especially, tend to utterly ignore the clumsy and abritrary Ruûnian calendar, giving dates and days only in the ancient calendar of Elfin Reckoning, which traces itself back to the very beginning of time.
Days of the week
Lôrde, Lûnde, Halümde, Solde,
Lythuéde, Gaide, Sabbatom
Weeks of the cycle
Lôrdaum, Lûndaum, Halümdaum,
Soldaum, Lythuédaum, Gaidaum, Sabbot
Cycles of the year
Lôrdoth, Lûndoth, Halümdoth,
Soldoth, Lythuédeth, Gaidoth, Sabbatoth
Dates among humans are usually quickly rattled off as a string of each of these identifiers. Using this system, the third day of the fifth week of the second cycle would be referred to as Halümde Lythuédaum Lûndoth (with a year given if one is discussing historical time, off course.) The first day of the Ruûnian year is always called AuLôrde.
Since they do not match up, every 17 years, the Lornian calendar “jumps” the Ruûnian, i.e. an entire elfin year passes within the span of a single human year and a new elfin year begins before the human year does. However, even this is not perfect, for every 324 years the caendarl falls back one year, in effect negating one of the “jumps” which occur every 17 years. (Terribly confusing isn’t it?)
