Any upcoming tournaments and matches and their dates?

I want to watch matches live whether it be pro league or premiership etc, but idk how to get dates and stuff as i am busy most of the hours with work and stuff and have only like 4-5 hours before sleep which i spend half playing the game itself.

Is there any site or something which keeps giving every date of matches if not link? I appreciate all kind of tournaments like premiership and challenger league and stuff.
