I’m glad you’re enjoying the game so far! Hint: the book code is made up of the 7 and another marking on the calendar put together.
I've been assuming it's the 7 and the Y making 70(seventy) is that not it?
The Y is not the hint, but the arrow pointing in that direction is. Think about what else it could mean.
honestly I'm pretty stuck QvQ
(Spoiler)
The arrow is pointing at February.
