Qirsyllvian Calendars

There have been many calendars used through Patria's history, but the most well known are listed here. All calendars divide the year into 403 days.

Zedylric Calendar
The Zedylric Calendar, also known as the Solramese Calendar, was first adopted at least four thousand years after the lifetime of the first seven lunaculi. Created by Solramese astronomers during the reign of Solram I, founder of the Kingdom of Solram, an ancient state once resting in central Eurodon founded in the wake of the Fall of the Zedylrian Empire.

The calendar was first adopted several years after the inauguration of the Kingdom of Solram – one of several empires that emerged out of the chaos that resulted in Zedylria's destruction – and uses the widely acknowledged year of Zedylria's end as start year, marking the first year and all years after as AFZ (After Fall of Zedylria), thus making years prior BFZ (Before Fall of Zedylria). The creators of the calendar viewed the Fall of Zedylria as a major turning point in history, and so used the year the empire fell as the base for the calendar, thus marking the year Zedylria fell as 0AFZ.

The most accurate of any previous calendar, this calendar was at first only used by the Solramese Kingdom to supplant the old calendar used by Zedylria, but has since been adopted by the majority of Patria. Even while the Kingdom of Solram has ceased to exist, it remains the most trusted calendars of Patria.

Tuzhu Calendar
The Tuzhu Calendar is the calendar used by the Tuzhu peoples throughout Huaxia, Zhonghua, and related countries.

It was invented by Huaxian astronomers during the waning years of the Chang Dynasty. The inventors of the calendar used the ascension of the Tian Dynasty to mark the beginning of the common era, so years prior are tagged TJQ [天於即位前|Tian yu Jiwei Qian|Before the Enthronement of Tian], while years since are tagged TJH [天於即位後|Tian yu Jiwei Hou|After the Enthronement of Tian]. Note: 0TJH = 421BFZ.

Wajin Calendar
The Wajin Calendar is the calendar used by the Wajin peoples and countries of Fuso and Yamatai's dependencies. The Calendar was adopted following the coronation of he first emperor.

Years prior to and after adoption of the calendar are referred to as ZT [前常|Zen Tsune|Before Tsune] and KT [来常|Ki Tsune|Since Tsune].
