The Sythian calendar is comprised of four parts-- the era, the day, the year, the sign.
Each era is consisted of every century (every 100 years equals 1 era)
There are 100 days in each year, after which the year will increase by 1.
As for the signs there are three separate signs- Juniper, Claudia, and Freya each the year after the next (while year 1 might be the year of Claudia, year 2 will be the year of Freya, and 3 will be the year of Juniper).
The correct way of organizing the dates are as followed: #:##:###:S
For example, Rolf Stahel was born on 6:14:99:J (6th era on the 14th day of the 99th year of Juniper)
