Calendaring and Time

Under the Tower Kingdom, Feodrians have standardized on Ælvy'l calendaring system, which subdivides each solar cycle (or year, the terms "cycle" and "year" are used interchangeably) into nine asymmetrical seasons (which function a bit like combinations of seasons and months under the Gregorian calendar). The seasons are further divided into weeks, consisting of six sunsets (commonly shortened to "sets" and are what we would call days) each. The number of weeks per season varies, but most seasons are ten weeks for a total of sixty sunsets. Each sunset is 20 hours: 10 hours of daylight beginning with dawn at 00'00" (time formats are HH'MM"), then ten hours of darkness starting with the sunset at 10'00".

Seasons (Months)

The Ælvy'l calendar is centered around the unique movements of Iotoros's three moons. While the seasons are not locked to the moons' orbits (they were actually originally based on the specific weather patterns in the coastal northeastern part of the continent), each moon has a different orbit and at their most dominant in the night sky (what we would think of as a "full moon") their unique mineral compositions reflect a different colored light. There is a single six-set period in which all three moons are dominant at the same time, which also coincides with Iotoros's annual orbit around its sun (technically the orbit lasts from Lavanda-5 to Lavanda-5, but the Ælvy'l calendar offsets the beginning of the season to coincide with the lunar event).
In the following table, Temperature and Precipitation are cited relative to the baseline range for a given region. For example, if a region's baseline temperature range is 18-22°C and its baseline precipitation is 1-3", a "high" temperature season will average at or above the upper bound of the baseline (in the example, perhaps 22-25°C). Likewise, a "wet" season indicates at or above the high range from the baseline (in the example, maybe 3-4").
The parenthetical numbers in the Dominant Moons column indicates how many weeks of the season that moon is dominant.

Season Details

Season	# Sets	Type	Temperature	Precipitation	Dominant Moons	Notes
Lavanda	60	Planting/Blooming	Moderate to low	Wet	Tsenkher (10), Ulaan (10), Nogoon (5)	The first week of Lavanda is a special event known as Ounghui. During this week, all three moons are dominant. The solar cycle ends on Lavanda-4 and begins on Lavanda-5.
Crinezha	126	Growing/Watering	High	Dry	Tsenkher (21), Nogoon (10)	Crinezha's 10th week is known as "Waterkuun" or, especially in Human regions, "Zeditia's Dance." The combination of Tsenkher and Nogoon in this week gives the night an aquamarine hue.
Amitolla	60	Harvesting/Planting	High to moderate	Average	Ulaan (10), Nogoon (6)	The 10th (and final) week of the season features Ulaan and Nogoon being dominant together. The brownish hue to their combined moonlight for that week is known as "First Deerhide."
Sula	60	Harvesting/Planting	High to moderate	Wet	Ulaan (10), Nogoon (4)
Ropah	60	Stable/Waiting	Moderate/high	Wet	Nogoon (6)	The 10th (and final) week of the season showcases Nogoon at its most singularly dominant, when Ulaan and Tsenkher are both receded. This week is known as "Faedistin" and the calming, foresty green moonlight is thought to be a sign of fertility and growth. Many cultural celebrations of love, sexuality, and nature occur during this time. The religious celebration of Glynthyra known as Récoltu occurs.
Vourdan	120	Growing/Blooming	Moderate	Wet	Nogoon (10), Ulaan (10)	In the 20th (and final) week of the season, Nogoon and Ulaan are both dominant again. This week is referred to as "Second Deerhide."
Krizohm	60	Growing/Blooming	Moderate	Average	Ulaan (10), Nogoon (4)
Qualn	60	Harvesting/Watering	Moderate to Low	Dry	Tsenkher (10), Nogoon (6)
Azorna	114	Hibernation	Low	Average	Tsenkher (19), Nogoon (9), Ulaan (9)	The 11th through 14th weeks of the season feature the first occurrence of the night illumination featuring both Tsenkher and Ulaan without Nogoon. This period of violet-hued nighttime has a lot of superstition and mysticism surrounding it, as older societies exercised many of their darkest urges including humanoid sacrifice, Maw Phase-spawned rituals, and celebrations of evil gods during this period.

Feodrian Moons

The three Feodrian moons orbit Iotoros at drastically different rates. This has the unique effect of creating various configurations of moon dominance in the night sky depending on the season, week, or even sunset. In addition, each moon has a specific mineral makeup which causes them to reflect light from Iotoros's sun in specific colors, particularly at their most dominant (or most full). The combinations of various dominant moons can create interesting visual effects at certain times of the year.
One noteworthy thing is that two of Iotoros's moons (Tsenkher and Ulaan) are visible in every night sky, at least partially, unless blocked by the much closer Nogoon. Despite their distinct orbital patterns, each moon generally appears to be roughly the same size in the sky, owing to their relative sizes. Tsenkher, for example, is vastly larger than the tiny Nogoon, but because Nogoon's orbit is so close to Iotoros and Tsenkher's is so remote, they appear to be similar but are never at any risk of collision.
Moon phases are described as either "dominant" when the moon is bright, fully colored, and large in the night sky, or "receded" when the moon is dimmer, more whitish, and smaller.

Tsenkher

The Blue Moon. Tsenkher operates on a long slow orbit in which it draws closest and most dominant (or of equal dominance) at the start of Lavanda. Tsenkher's "new" phase, or least dominant, occurs during the tenth week of Ropah. This cycle means Tsenkher orbits Iotoros in its entirety once per solar year.
When dominant, Tsenkher is about the same size as a medium full harvest moon in Earth's night sky and it gives off a brilliant medium-blue light. This pure blue tinting is most pronounced during the 10th week of Azorna (about halfway through the season) while Nogoon is receded and Ulaan hasn't quite entered its dominant phase.

Ulaan

The Red Moon. Ulaan has an orbit similar to Tsenkher's, but much closer to Iotoros. Therefore, Ulaan orbits Iotoros three times per solar cycle with its most dominant coming in the first week of Lavanda, the last week of Amitolla, the last week of Vourdan. Ulaan is most receded the 11th week of Crinezha, the 10th week of Ropah, and the 10th week of Qualn.
When dominant, Ulaan appears quite large and close in the sky, it's rich crimson coloration and heavily textured surface fascinating generations of stargazers. Ulaan's orbit frequently coincides with the other moons' dominance, so the only real purely red nights occur in mid-Vourdan and again in late Krizohm after Second Deerhide. These periods are known as Sanguina and have some cultural significance across the Kingdoms, though Sanguina is most closely associated with the Orcish Kingdom, where many of their ritualistic combat traditions took place.

Nogoon

The Green Moon. Nogoon orbits Iotoros incredibly quickly compared to the other two moons, making a complete cycle every 20 weeks. Nogoon is also much, much smaller than the other two moons, but it's proximity to the planet's surface makes it appear of a similar size, partcularly to Tsenkher. Nogoon is also the only moon that has an orbit we would recognize on Earth in which it is completely invisible in the Feodrian sky when it is receded. It also is the only moon that appears less than full, with Iotoros casting straight-edged shadow over the moon's surface, moving from bottom to top.
When dominant, Nogoon appears round a full in the sky, less intensely large than Ulaan, but still with discernible features visible to the naked eye, including water, vegetation, and the signature greenish mineral component, which some scholars have guessed to be either Jade or oxydized copper.

Weeks, Days, and Time

Each week within a season lasts six days. The days are named Almset, Bornset, Creedset, Duneset, Elmset, and Fireset.
Generally speaking, most cultures in Feodris set aside Almset as a day of rest, with Fireset (particularly the evenings) frequently being considered the time for socialization and gatherings.
Since each set begins with sunrise at 00'00", most cultures have settled their circadian rhythms to sleeping between about 13'00" and 19'00". Night owls will push this a bit further into the nighttime hours, perhaps 15'00" through 02'00" the next set. Agricultural workers who tend to rise before the sun will back this off, considering bedtime to be anywhere from 10'00" to 12'00", rising at 16'00" to 18'00".
Most businesses operate between 03'00" and 09'00", or those that feature longer hours may open at 01'00" and stay open until 11'00", 12'00", or even later.
Feodrians rarely concern themselves with time units less than one minue.
