Clubbing on a weekday?

Hey im planning a trip to Europe from in October and due to some plan changes i’ll be visiting Berlin for 4 days.

Thing is, 4 days thru the week… I have a friend in Berlin that says clubs are only open on weekends but I’d like to think there is still hope for me.

I love Techno, House, Trance. Electronic music en general but those are my favorites.

Does anyone know about clubs/events happening during the week of the 20th to 24th of October in Berlin ?
