Do the play in games take place on wednesday/thursday or thursday/friday?

Hey guys, As a passionated league player i follow the worlds at the moment. But i am kinda confused now, the riot employes on stream talked about the play in games beeing settled on wednesday & thursday, but if i look up the official riot page it says thursday/friday....

As they take place in germany pretty early in the morning i do not wanna wake up for nothing....

So could somebody tell me when they take place now?

Would be rlly thankfully.

Greetings from Germany
