Board Game Arena

How can you tell which teal color on the calendar is the end of the game?
I have a few games going and some games I cannot tell if the game is coming to an end or if its the first scoring.

all level 1 buildings are replaced by the level 2 buildings at the second scoring. But well you can only use that as a trick if you know which buildings are which level. (if the level 2 buildings are present the next blue marker will be final scoring)

cheers,
Sawyer

Thanks, that helps....
I'm sure in a few more games I will have it figured out.
