Here is a copy of the Leauvalar Calendar, which shows the phases of the moon, notes the first day of the various seasons, solstices and equinoxes, and national, regional, and religious holidays. (I haven't had time yet to determine names and details for these holidays, but we know what day they are so Clerics may celebrate instead of adventuring).
Four Seasons spread over Thirteen Months, Twenty-Eight Days each, for a Total of 364 Days a Year.
