The Egeriac Calendar is a lunisolar calendar used today predominantly in the Federal Republic Of Notzel for dating. The date format of the Egeriac Calendar is dmy(day-month-year).


Day and hours

Traditional Egeriac timekeeping practices required the use of unequal time units: 12 daytime units from local sunrise to local sunset, and 12 night-time units from sunset to sunrise. The 12 daytime units and the 12 night-time units are further divided into two subgroups for the sake of naming. A day begins and ends at the midnight.

The practices of determining the length of daytime hours and night-time hours based on sunrise and sunset was abandoned in the 19th century when clocks became widespread and the need of standardized units of time became important due to the industrialization of Notzel.

The names of days are named after the lunar phase. Below is the name of each day in a month:

Day 28 Oxxi nemeth zogom motzor Day of near hollow moon
Day 29 Oxxi nemeth zogom Day of hollow moon

In practice the "Oxxi nemeth" part of the name of each day is often omitted.


In general, the Egeriac week is a cycle of seven days, but there are several circumstances where there are 8 days in a week. 52 weeks form a cycle called nidruth(plural nidruyoth). In most years, a nidruth has 365 days, but one out of four nidruyouth has 366 days, that is, the length of nidruyoth corresponds to the length of a solar year, and the "nidruth" with 366 days is called nidruth zodon(literally "long nidruth")

The last week of every "nidruth" has 8 days; besides, the 26th week of a "nidruth zodon" also has 8 days. The 8th day of a week is inserted between "Oxxi Komos" and "Oxxi Per" to make sure that the day for every winter solstice is Oxxi Gnul.

Below is the name of each day in a week:

Name in Egeriac Meaning Notes
1st day Oxxi Gnul Day of Beginning
2nd day Oxxi Nov Day of Ground
3rd day Oxxi Mer Day of Water
4th day Ox Komos Middle Day The name is changed to "Ox han heKomos" in weeks with 8 days
Ox han heKomos Day before the middle only used in weeks with 8 days
8th day Oxxi haf heKomos Day after the middle only used in weeks with 8 days
5th day Oxxi Per Day of Fire
6th day Oxxi Pech Day of Air
7th day Oxxi Kun Day of End

Usually Oxxi Kun is the rest day in Notzel, traditionally it was also they day for worshipping Hosha.


The mean period of the lunar month (precisely, the synodic month) is very close to 29.5 days. Accordingly, the basic Egeriac calendar year is one of twelve lunar months alternating between 29 and 30 days:

Egeriac Month Length Gregorian Meaning
Teth 30 Sep–Oct Head, first
Veder 29 Oct–Nov Flower
Mogdath 30 Nov–Dec Joy
Daxtoch 29 Dec–Jan Harvest
Meif 30 Jan–Feb Heat
Deven 29 Feb–Mar Fruit
Bod 30 Mar–Apr Wood
Hem 29 Apr–May Fog
Gmuch 30 May–Jun Frost
Remech 29/30 Jun–Jul Snow
Mrich 30/29 Jul–Aug Rain
Vanol 29 Aug–Sep Tail, end

In leap years an additional month, Deven Non (30 days) is added after Deven, while the regular Deven is referred to as Deven Nof.


The years are not recorded in numbers, but in terms of 76-year cycles. From the 4th century onwards, we observe the usage of 76-year cycles. The 76-year cycle is known as kamog cycle and was introduced in 355 CE, when the first united Egeriac republic was formed. The first year of the first kamog started in 355 CE. The cycles were counted by ordinal numbers, but the years within the cycles were never counted but referred to by special names. Within each cycle, the name of the year is determined by the combination of the four traditional elements(nov "Ground", mer "Water", per "Fire" and pech "Air") and the 19 zodiac signs. The element-zodiac designations recur in cycles of 76 years, starting with a ground rat(Egeriac: nov magan) year. These large cycles are numbered, the first cycle starting in 355 CE. Therefore, 430 CE roughly corresponds to the ground rat year of the 2nd cycle(Egeriac: he-gezzi nov magan he-kamog avorren), and 2020 CE roughly corresponds to the water house year of the 21st cycle(he-gezzi mer num he-kamog namod tonon). This practice of recording years is comparable to the way of naming years in the Tibetan calendar.

New year

Leap years

The Egeriac calendar is based on the Metonic cycle of 19 years, of which 12 are common (non-leap) years of 12 months and 7 are leap years of 13 months. To determine whether a Egeriac year is a leap year, one must find its position in the 19-year Metonic cycle. Within a metonic cycle, there is one leap year for every three years, and there are two leap years for every 5 years.

However, the Metonic cycle is just a rough rule, actual observations may change the positioning of leap years, creating further exceptions. The actual position of the leap year is determined by the government.
