Usage notes

Common mistakes

以内 always comes after the number or range expression, not before (e.g., 三天以内, not 以内三天).

Formality

Common in both spoken and written Mandarin; can be used in formal and informal contexts, but note that it refers to 'within a range' or 'less than' when following numbers.
