This rule is to avoid confusion in the chapters.

So like Chapter #, Day #?

yea

So chara is day 3?

No. It's whatever day it's in. The first chapter is day one because it's the first day of the series. Chapter 2 is still in day 1 because it's still the same day as day 1.

Oh.

ye but sometimes two chapters are at the same time

They will have the same day then.

each person has their own day count?

Yes. I'm still in day one because I haven't done a chapter in day 2 yet.

i see. im still in day 1 two cuz i only did 2 total chapters, chapter 3 prolly gonna be day 2
