How it works

What did the librarian tell him? He passes the library information he heard on to a friend.

「んだって」 marks hearsay or reported speech. The information comes from someone else, rather than your own guess.

This is a casual expression used among friends. For formal or polite reporting, use the 「そうです」 you already learned.

Use the plain form of verbs and い-adjectives, as in 「開いている+んだって」.

For nouns and な-adjectives in the present affirmative, use 「な+んだって」, without 「だ」.

In the summer example, 「なる」 expresses a future change; 「んだって」 simply shows that the information was heard from someone else.
