Calendar

The Aecus Concord calendar, month by month

Before the Flux, every nation had its own languages, and own way of tracking time. When the Aecus Concord was founded, a common language was established, and a common calendar was founded which honored all the major religions.

The sun and moon move in tandem, somehow linked. But while the sun rises around different elemental poles over the course of the year, creating seasons that differ by region, the phase of the moon looks the same to everyone worldwide. And so the new moon was chosen as the hallmark of a new lunar year.

Months of the year

A year in Aecus consists of 368 days: 12 months of 30 days each, plus 8 dedicated days for each of the elemental apexes (i.e. summer solstices), when the sun sits highest in the sky centered at one of eight aligned elemental orientations.

Days of the week

The Aecus common calendar uses five-day weeks, with six weeks per month:

The solar and lunar cycle

A curious feature of Aecus’s solar/lunar annual cycle is that the sun does not move at a constant speed around the elemental poles, but rather spends more time each year near the Arenan quadrant. Some scholars believe this is due to Pelor’s affinity for the elements of Air and Fire. As a consequence, some nations have an imbalance of seasons, as noted in the following table.

Furthermore, the moon does not move through its phases evenly throughout the year, but rather spends substantially more time waxing than waning, reaching its fullest at the midpoint between the Arenan and Ignan solar apexes, and its newest at the midpoint between the Terran and Glacian solar apexes.

See the Equilibrium calendar spreadsheet for a full breakdown of the Aecus Concord calendar, and how it aligns with the various regional calendars discussed below.

Regional calendars

Even with a common calendar system, many regions also use their own calendars colloquially. The following calendars are still in use in certain regions.

Aquan

The Aquan year is divided into 13 months of 28 days each, with an additional festival day for each of the four seasons.

GM’s note: the Aquan calendar was adapted from the Eberron calendar.

Ignan

Before the Flux, the Radiant Union of Pelor and the dwarves of the Mountain shared a calendar aligned to their weather.

The Ignan year is split into 12 months of 28 days each, and four eight-day festivals, each placed at three-month intervals. The months and festivals are commonly referred to as the Dozenmonth of Luna and the Four Festivals.

12 Sunsebb Lacysnows Wolf Winter

The first of the month is always a Starday, and the rest follow as shown below:

The festivals use the same day names as regular months for the first 7 days, with the 8th and final day of each festival known as Festday, as well as given a season-specific name: Winterday, Greenday, Moonpeak, and Feastday for Needfest, Growfest, Richfest, and Brewfest respectively.

GM’s note: the Ignan calendar was adapted from the Greyhawk calendar.

Elyria

Like the Aecan calendar, the fey calendar is divided into 12 months of 30 days each, plus 8 special days. But unlike others, the elves celebrate moderation rather than extremes. As such, rather than marking when solstices occur, they celebrate seasonal midpoints, illustrative of their philosophy of balance.

Years are counted since the last planting of the World Tree, with each planting referred to as a Cycle—e.g. Year 985, Cycle 37.

Months are divided into 10-day segments known as tendays, with no names per day. For example, 21 Hammer is the 1st day of the 3rd tenday of Hammer.

Trell

On the islands of Trell, the year is sorted into 12 months of varying length: 29 to 31 days, depending on the month. There are also two special days highlighting the days before the winter and summer solstices respectively.

The months are named according to infernal ideals, with each month having an associated Asmodeal lesson known as a slogan, which are taught to Trell children to foster self-improvement and success as they develop.

Month Days Season Objective Slogan Connotations
Ursa 1 Eve of winter     market and seasonal contraction and scarcity
Abadius 31 Early winter Plan Bargain shrewdly with others toward common goals preparation, civilization, law, transaction, patience, neutrality
Calistril 29 Mid winter Grasp Seize sudden opportunities at crucial moments desire, confidence, revenge, duplicity, emotion

Lamashan 31 Early-mid autumn Fail Indulge in loss and contemplate worst-case scenarios madness, monsters, nightmares
Neth 30 Mid-late autumn Subsume Incorporate fear and despair into holistic understanding magic, duality, madness, creation & destruction, omniscience, surrender

The seven days of the week are Moonday, Toilday, Wealday, Oathday, Fireday, Starday, and Sunday. But which week days fall on which days of the year varies year by year (sound familiar?).

GM’s note: the Trell calendar was adapted from Golarion’s Absalom Reckoning.
