Thurásin Standard Calendar

When I left home, it was the 386th year after the Collision. Here, it is the 33rd year after... Mer contact, I think? I must confess, I don't think I will ever understand this Thurasin system.

While no country or culture in Thurásin is identical, many have come together to use a unified calendar and way of arranging years, to minimise confusion in diplomatic and trade negotiations.

Origins

The Thurásin Standard Calendar began its life in central-west Thurásin, on the banks of the River Tsädh, due to the large variety of groups which relied on the river for trading amongst each other. Representatives from nearly every town and group along the river came together at a nominated location to talk numbers, finally settling on an Era system, and agreeing that the start of the next thawing season would mark the first years in their new calendar. Years prior to the beginning of the Thurásin Standard are counted either in local calendars, or in negative numbers as part of an "Era of Origins".

Conversion

Converting between the Thurásin Standard and the Abravosti calendar is an inexact science, owing to the limited contact between the two continents. According to the only primary sources in Thurásin about the latter, the year 386 After Collision aligns with the year 33 Contact.
While both calendars start in equivalent seasons, being that of the thawing and harvest respectively, its highly likely they do not neatly fit into each other due to their distance and differences in the lengths of years. For simplicities sake, Abravosti years are used 1:1.

Thurásin Eras

Eras in the standard calendar start the next thawing season after a major defining event, or approximately every 100 years if no such event occurs. As such, there are some eras which are significantly shorter than others. Each era starts at year 1, and counts upward until the next era begins. Many of the initial eras are specific to central and southern Thurásin, but later becomes more all encompassing as more people adopt the calendar.
