The time system in Eriania is based on two things: the day and the month. Since, as of yet, there has been no urge to keep record of anything, there has not been a named year. Regardless, the time and date system is written as follows
[Month number], Day, [Date Number]
While there are no years per se, there are also no named months. All months are just a number in the eyes of Erianians, with a set amount of 8 months and 40 days per month. The days, though simple, are named. They are as follows:
Odo, Eudo, Ido, Ado, Endo
The simplistic nature of the date system comes from a lack of record keeping. With no one to keep track of anything, there has yet to be a need for making anything more sophisticated.
