So I don't have to go looking this up again.
* One day on Auldrant lasts 24 hours.
* One week on Auldrant lasts seven days, each day is named after a fonon type. Their names are, in order, as follows:
o Remday
o Lunaday
o Ifritday
o Undineday
o Sylphday
o Loreleiday
o Gnomeday
After Gnomeday, a new week begins with Remday again.
* The planet Auldrant consists of thirteen months. Their names are, in order, as follows:
o Rem Decan
o Sylph Decan
o Undine Decan
o Gnome Decan
o Ifrit Decan
o Shadow Decan
o Shadow Redecan
o Ifrit Redecan
o Gnome Redecan
o Undine Redecan
o Sylph Redecan
o Luna Redecan
o Lorelei Redecan
After a full cycle of thirteen months, one Auldrant year ends and another begins.
