The Calendar

The calendar is marked by the number of years since the impact
of miasma, known as After Impact (Or AI).  The year is divided
into twelve even months, each month consisting of 4 weeks (or
28 days).  This makes one year equal 336 days.  Unlike the
calendar we have on earth, the FFCC calendar is named after
various avatars of the elements.  The beginning of the year
starts in the cold of winter, then goes on to spring, summer,
fall, and then back to the first half of winter before ending.

The year that the game is starting in is 1360 AI.

The months are, in order:

 Shiva
 Fenrir
 Ramuh
-Odin
|Leviathan
|Palidor
|Ifrit
|Phoenix
|Alexander
-Shoat
 Titan
 Bahamut

The caravan leaves at the beginning of Odin and is expected to
return come Shoat.
