Special Calendar Days:
Midwinter: Midwinter is known officially in Cormyr as the High Festival of Winter. it is a feast where, traditionally, the local lords of the land plan the year ahead, make and renew alliances, and send gifts of goodwill. To the common folk throughout the Realms, this is Deadwinter Day, the midpoint of the worst of the cold.
Greengrass: Greengrass is the official beginning of spring, a day of relaxation. Flowers that have been carefully grown in the inner rooms of the keeps and temples during the winter are blessed and cast out upon the snow to bring rich growth in the season ahead.
Midsummer: Midsummer, called Midsummer Night of the Long Night, is a time of feasting and music and love. In a ceremony performed in some lands, unwed maidens are set free in the woods and "hunted" by their would-be suitors throughout the night. Betrothals are traditionally made upon this night. It is very rare indeed for the weather to be bad during this night -- such is considered a very bad omen, usually thought to foretell famine or plague.
Highharvestide: Higharvestide heralds the coming of fall and the harvest. It is a feast that often continues for the length of the harvest so that food is always on hand for those coming in from the fields. There is much traveling about on the heels of the feast, as merchants, court emissaries, and pilgrims make speed before the worst of the mud arrives and the rain freezes in the snow.
The Feast of the Moon: This festival, also called Moonfest, is the last great festival of the year. it marks the arrival of winter and is also the day when the dead are honored. Graves are blessed, the Ritual of Remembrance is performed, and tales of the doings of those now gone are told far into the night. Much is said of heroes and treasure and lost cities underground.
Shieldmeet: Once every four years, another day is added to the year. This day is part of no month and follows Midsummer Night. Known as Shieldmeet, it is a day of open council between nobles and people, a day for the making and renewing of pacts, oaths, and agreements. It is a day for tournaments, tests and trials for those wishing to advance in battle fame or clerical standing, for entertainment of all types, particularly theatrical, and for dueling.
