Karthian Calendar

The Karthian Calendar is a 13th month calendar with three 11 day weeks in each of the months. The calendar was created by B'jova Rakarren Cartis. It is the standard calendar used by the majority of countries on Karth. The Calendar itself was used by the Gold Dwarves for their until existence, but was never used outside Gold Dwarf culture until the rise of the Esterackian Empire.

Dates and Seasons
Due to the months not being a multiple of 4, certain season overlap in a month. How the people handle this that in any part of the month they consider it one season more than the other. This has created disputes, and during the Bizuqui Fey era there were many wars, and this issue wasn't even solved during Setting The Seasons Straight.

Years and Era
Throughout history of Karth, how counting years has been a heavy topic of debate. Since every few thousand of years, a reset is made. And while this system works during each block. As an overall counting system, it is more awkward. Many citizens either count all years since the earliest point as one block, rather than just many blocks. This counting system has also been criticized as being more awkward then the current. As if more points on the timeline can be found, more years will have to be added to even out the disparity.
