Register and Nuance
"終日" is more formal and literary than everyday expressions like "一日中" (いちにちじゅう). It is suitable for written reports, news, or formal conversations. Using "終日" in casual speech might sound stiff or old-fashioned.

Learners sometimes confuse "終日" with "一日中," which also means "all day." While both are correct, "一日中" is more common in daily conversation, and "終日" is preferred in formal or written contexts. Choose based on the situation to sound natural.
