I know people (me being one of them) are sometimes struggling with the different time measurements in and out of the game, so I made this guide.
It turns out that the Aetolian weekdays are static, making it easier to refer to which days of the week one might be most likely to be around. For example, Teani would be more likely to be awake and aware on a Tisday or Falsday, while Kinsday appearances would be very scarce. During RL weekends, certain Quensday appearances are also likely, especially if planned ahead, making Gosdays less likely.
I hope you find this helpful in some way!
*DISCLAIMER: it might not be perfectly accurate, but it's close enough, I think!
