The Standard calendar is the most easily recognized and the most widely used. When any two people from different countries or cultures want to coordinate dates, they use the Standard calendar.

The Standard year of 331 days is pinned to the cycle of seasons. The standard week is 7 days, and the year is subdivided into eleven months of either 31 or 29 days (based on the cycle of the greater moon Seasta, roughly 30.09 days). Three months make up the season Hiberna (winter), five months make up Augea (spring-summer), and three months make up Demeta (autumn).

Standard years are numbered to coincide with the year numbering of the Imperial calendar (see below).


Although the Standard calendar is used by almost everyone, chronomists at the imperial college have cataloged a number of other calendars in use throughout the world. Here are a few:


The Imperial calendar is the official calendar of the Imperium Magna Patria, and is used on all official missives of state and other documents of the empire. The year is divided by a hierarchy as follows:

  • simplex is 1 day
  • duplex is two simplexes (2 days)
  • triplex is two duplexes (4 days)
  • quadruplex is two triplexes (8 days, a day longer than a standard week)
  • pentuplex is two quadruplexes (16 days)
  • hextuplex is two pentuplexes (32 days, a bit more than a standard month)
  • septuplex is two hextuplexes (64 days)
  • an octuplex is two septuplexes (128 days)
  • a nonuplex is two octuplexes (256 days, closest equivalent to a standard year)
  • a decuplex is two nonuplexes (512 days)

The imperial year is defined as 331 simplexes (to keep it in line with the cycle of seasons), or when written in the official format of the Imperial calendar, “NSQDS” (also written as “IOIOOIOII”). The current Imperial Year is 844. Years are numbered sequentially, starting with the founding of the Empire and the crowning of the first Emperor in year 1.


The Gnomish calendar does not make intuitive sense to most people at first glance, but arcanists and others who practice magic find it very useful in determining when the ebb and flow of etheric energies will peak.

  • Jōṭi (“pair”) is two days
  • Tokuppu (“set”) is three pairs (6 days, a day short of a standard week)
  • Niṟaiya (“lot”) is five sets (30 days, roughly equal to a standard month)
  • Toṭar (“series”) is seven lots (210 days)
  • Kaṭṭamaippu (“configuration”) is eleven series (2310 days)

If the usefulness of the gnomish Kaṭṭamaippu is not immediately clear, consider that it is exactly one standard week short of 7 standard years. When certain superstitions say that a person will have good luck for 7 years, it is almost always a misunderstanding of the Kaṭṭamaippu. The gnomish origin of such superstitions is the idea of “a Kaṭṭamaippu of good luck, and thereafter a Tokuppu of bad luck”.

It’s also worth noting that one Kaṭṭamaippu is exactly the amount of time from one syzygy to the next of the greater moon Seasta, the lesser moon Fánaíochta, and the sun.


Dwarven culture has no calendar. This is a vestige of the long gone ages when dwarves lived entirely underground, and did not experience the passage of seasons or the cycles of the heavens. Instead, dwarves simply kept count of their circadian cycles. Thus, the Dwarven Count is the closest analog to a calendar that exists.

Interestingly, the Dwarven Count decreases over time (officially, at dawn each day): 611,839, …838, …837, etc. It will reach 0 in approximately 1,848 years; the exact date should be Cheken 3, 2691. However, because the Dwarven Count is very old and has been going on for so long (the oldest historical reference to the Dwarven Count puts it at 1,009,523, which would have been about 1,200 years ago), no one alive today is exactly sure what it is counting down to. Most historians speculate that the Dwarven Count was begun by a doomsday cult.

The Standard year 844 begins on Dwarven Count 611,992 and ends on 611,661.
