“Most cultures of Faerun follow the Calendar of Harptos, named for the long-dead wizard who invented it. The Faerunian year is 365 days long, marked by the passage of Toril around the sun. The year is divided into twelve months of thirty days, loosely coinciding with the waxing and waning of Selune, and five annual holidays. In a lieu of weeks, each month is divided into three tendays, also known as rides. Once every four years, Shieldmeet is added to the Calendar of Harptos as a “leap day” immediately following Midsummer night."

Seasonal festivals:
Midwinter: Although this holiday is generally known as Midwinter, it is often celebrated under different names. For example, the High Festival of Winter is a feast day used by nobles and monarchs to mark or renew alliances. Deadwinter Day is a somber day noted mainly as the halfway point of winter, with hard times still to come.
Greengrass: The start of spring is traditionally a day of peace and rejoicing marked by the display of flowers (even if they need to grown in a hothouse during the winter months) that are worn or given as sacrifices to the gods who have brought life back to the world.
Midsummer: The midpoint of summer is a time of feasting and love, dalliances, betrothals, and traditionally good weather. Bad weather on this night is seen as a sign of ill fortune to come.
Shieldmeet: This quadrennial festival follows Midsummer night. It is traditionally a day of open council between the ruled and their rulers, and the renewal of pacts. In addition to theatrical entertainment, many tournaments are held in Shieldmeet, allowing the brave and the foolish to try to prove themselves.
Highharvestide: The autumn harvest is marked by feasting and thanks. Many folk travel in the wake of this festival before the worst of winter’s bite makes the roads and waterways impassable.
The Feast of the Moon: This holiday celebrates ancestors and the honored dead. During the festival, ancestral tales are recounted, and the stories and myths that bind cultures are taught anew.
