When do leagues end each week for placement?

From my understanding, the chance to move up is at the end of each week? What day and time do they restart each week to move up? I'm not entirely sure I understand the league format. 

I just noticed I was part of a "wooden league" apparently on my rating for Rapid while I progress in rank based on blitz wins (this is the only type I have played on chess. com). This I am already ranked #4 in this league I would appreciate it if someone could explain why I am there and how it works...

Same problem here. Its says there is 0 days 0 hours left to finish but people are still increasing their points

Same problem

Leagues end at 8 pm UTC every week. It shows 0 days 0 hours when there's less than an hour left, so even if there's still some time left.

Thank you

That’s because it ends in minutes, but doesn’t have a display to show that. It ends in less than an hour, but nothing to show how many minutes.

My time right now is 6:39 pm UTC. However, my league time shows 0 days 0 minutes. I think this time is also affected by the daylight saving time in the USA.

Are you sure it ends at 8 pm because it says one hour left now?

Divisions reset at 12 pm Pacific (8 pm UTC). 

Sundays 

Since California USA is more or less the last place on earth to change over, in some countries it will already be Monday... for example in Indonesia it would be early Monday morning.

So asking which of 2 days is reasonable... but you should ask Sunday or Monday
