This is an alternative Greyhawk calendar for use in the Savage Tide campaign.
The year is plit into twelve months of twenty-eight days each. Different cultures have their own names for the months and festivals. The months and festivals are commonly referred to as the Dozenmonth of Luna and the Four Festivals.
The days are reckoned in weeks of seven days each. The days of the month are: Starday, Sunday, Moonday, Godsday, Waterday, Earthday, and Freeday. Godsday is commonly associated with worship, and Freeday with rest. The remaining days are considered "work days." An interesting feature of the Greyhawk calendar is that the days of the week always occur on the same day every year, a result of the year having a number of days divisible by seven.

Year, Seasons, and Celestial Bodies
The Oerdian year has 336 days, divided into 12 months of 28 days each. Solar and lunar months coincide, with the large moon, Luna, having a period of 28 days and the small moon, Celene, having a period of 84 days. Luna's new moon is always at the change of the months, while Celene's new moon is at the beginning of each season.
There are eight major astronomical festivals of the the year, four solar and four lunar. The solar festivals are the winter solstice, spring equinox, summer solstice, and autumn equinox. The lunar festivals are when Luna and Celene are full at the same time and happen exactly 42 days after the solar festivals. At each solar festival, both moons are new.
There are also five visible planets, named Atroa, Sotillion, Telchur, Wenta, and Velnius. Atroa is the innermost planet and visible at the spring solstice, Sotillion the second planet and visible at the summer equinox. Telchur is the forth planet (Oerth being the third) and most visible around the vinter solstice. Wenta is the fifth planet, most visible in autumn. Velnius is the sixth and final planet, barely visible from Oerth and not associated with any season.
All celestial bodies are named after the gods they correspond to, tough not all people recognize them as such.
Seasons and Climate
There are four universally recognized seasons. Their effects vary widely by geographical area. In general, the north and south of the Flanaess has easterly winds, warm in the south and cold in the north, both humid and bringing a lot of rain and snow and making the climate relatively stable. There are westerly winds and currents to the north and south of the Flanaess bringing warm water to the Dravmidj and Solnor Oceans. The weather in the Thillonieian peninsual is particularily violent and snowy, with a warm sea current from the east and cold winds from the west.
Inland areas have a more variable climate and are much drier. Summers days are warm, winter nights are icy cold even far to the south.
Dominant easterly winds brings rain and snow all over the Flanaess.
When the winds let up, the cold comes to the north. Sudden storms are common, though the weather is generally fairly sunny. Winds tend to be from the north and north-east.
Westerly winds clean up the skies, tough this is a season of great instability and there are generally a few easterly rainstorms, especially in coastal regions. These rarely blow very hard or very long.
Weak south-westerly winds bring dry, warm air, perfect for maturing cereals.
Months and Weeks
Each month consists of four weeks and is both 1/12 of a year and one cycle of the larger moon, Luna. Luna is in new moon at the beginning of each month and full on the 14th of each month. The new day begins at midnight.
The tides are cyclic over the month. At the beginning of the first and third week, high tide is at dusk at dawn. Depending on the latitude and the time of year, the actual time of sunrise varies, but high tide occurs at 6 am and 6 pm at the beginning of each month. At the beginning of the second and fourth week, high tide is three hours later.
