Halloween show times

[Disneyland1955*]

I have been for halloween before but I cant remember much about the park operation hours and the shows. Is it like summer where the park is open late or does it still close early over halloween. and also does anyone know if there is normally the fantasmic shows all week or just the weekend and how many one or two. so many questions lol. thank you so much for your help and input.

I think it just depends on what day you go and if its a weekend and all that
