Jade makes this calendar for Owen in the next chapter. I felt that it was better to post it as a [Guide] chapter since the months/seasons are different in this world.

This calendar originated from both Khelios and Dalios (The God Of The Sun).

Also, the days in Adrios are more or less the same as ours:

Sundas (Sunday)

Mondas (Monday)

Tusdas (Tuesday)

Wedas (Wednesday)

Thurdas (Thursday)

Fridas (Friday)

Saturdas (Saturday)

Our naming scheme is used (Monday, Tuesday, etc.), but it's considered to be an informal way of saying it.

Jade will handle most of the accounting tasks, so having a calendar is important. Also, since you guys wanted to see Owen as a traveling Merchant, knowing the date is important.

Jade will explain this calendar in the next chapter as they get ready to open.
