Holidays

Are there new years celebrations in the Valley?
Short answer is no.
Most celebrations are centred around religious festivals.
Mitra's celebrations is held on Ardensday (Sunday), on the night before Mitrasday (Monday). For this reason, Ardensday is a day of rest for most people.
Thyr's celebrations are held on the last day of every month. On this day, grievances are brought before the King/Mayor/Lord/Haku, and resolutions are sought. This usually co-incides with church-going and a general dressy atmosphere, as people try to not look too shabby in front of their Lord.
A formal occasion, but generally looked forward to by those who need more justice in their lives. This holiday coincides with the council meeting, which is after all just another part of the idea of finding resolutions to common problems.
Muir's celebration is on the eve of battle, generally a light fast (before a big breakfast) and an abstinence from distractions like alcohol or light entertainment.
On Confirmation day (A day where a new batch of paladins undergo their rites), the opposite is observed. Food is plentiful, and there are normally displays such as jousting, knife throwing or archery competitions
Vanitthu doesn't believe in ceremonies, since his faithful are usually in charge of organising and guarding such things, they see no reason to make more work for themselves. Rather, celebrations in Vanitthu's name involve going to the pub and celebrating successes in guarding, such as arresting a dangerous criminal, or surviving a melee.
Freya oversees the harvest feasts, as well as the celebrations after a successful hunt (such as the Draygonsfel).
Arden's followers once held celebrations during eclipses, but those days are long gone.
Telephos, the Lord of Crops and Seasons would seem a more logical candidate for harvest feasts, but his followers )and holy books) frown on celebrations that thank gods for the results of man's labor. Rather, Telephos's celebration is held on the first thaw and first frost of the year, recognising the role the elements play in man's struggle.
Their parties aren't very much fun.
