Dantrian calendar is the most used calendar on the Continent. It was established by the Western Dantrian civilization.
Based on the idea of cycles and the Quun Tirtoir (infinite staircase) of Lolion, the calendar conceptualizes history as "revolutions" of the spiral. The spiral does not turn by itself, but instead must be turned by the deeds of the living. Each important event turns the spiral farther, thus leading to the movement of time. Time stops if great deeds are not accomplished. From this idea comes the common phrase, prevalent in many Continent languages, "turning time", which means to change the world in a significant way.
In the calendar, each revolution is exactly 2000 years. Recorded history begins over 5000 years ago, with the current revolution being the third.
|First revolution||Second revolution||Third and current revolution|
|2000 years||2000 years||1100 years so far|
Dates are followed by letters FR, SR or TR, denoting first, second or third revolutions. For instance, 863 SR would be the year 863 of the second revolution. Centuries are abbreviated as "CFR", "CSR", etc. So, the current century is 11th CTR, which stands for "11th century of the third revolution". It can also be written as "11th century TR". In a sentence, revolutions and their ordinal numbers are typically not capitalized: "first revolution".
While in English such a system would pose a problem, since many ordinal numbers start with the same letters (first, fourth, fifth, etc.), the calendar's numerals are in Mandae, which uses separate letters for each of the ordinal numbers up to twelve. Thus, the dantrian calendar might run into problems only after the twelfth revolution.
The calendar divides the year into 12 months, which allows researchers to apply the usual month labels to the dates. Months don't have their own names, but are instead referred to by the Mandae ordinals: first month, second month, etc.
The dates, however, use a decimal system, as the widespread adoption of the Mandae numeral system and the current form of the Dantrian calendar came much later. Therefore, the inhabitants of the Continent treat years as obeying a very special, somewhat alien numeric system, different from the usual arithmetic they use in everyday life.
