Is it correct to say : all the day, all the week, all the night, all the summer? I always say : all day, all week, all night, all summer. Am I right? Is there a grammatical rule to follow in this respect?
You are partly right; "All week" and "all day" are fine. Sometimes people say "the whole day" or "the whole week" to emphasize the length of time, but "all the day" doesn't sound fluent. You could say "all week long" or "all day long" also to emphasize the duration of time.

You would use "all the" before plural nouns and non-count nouns:
all the people
all the information
