It seems that even CEDICT is full of the common English usage mistake confusing the adjective "everyday" with the adverbial phrase "every day". This means many dictionary sites and apps such as Pleco are also infested with this error.
Wiktionary, on the other hand, is still missing Chinese translations for many of the synonyms of "everyday". I don't have access right now to a quality bilingual dictionary.
So, which Chinese terms are the best for the correct sense of English "everyday", which means "commonplace, mundane, ordinary, quotidian, unremarkable, etc"?
I feel it might be 日常 but there's so much poor literacy in the public-edited dictionaries that I can't trust them.
