‘限期’ is a compound noun meaning 'deadline' or 'time limit' — the fixed point in time by which something must be completed or action taken. The first character, 限 (xiàn), means 'to limit' or 'restriction'; the second, 期 (qī), means 'period', 'term', or 'due date'. Together, they literally convey 'a limited period' — emphasizing not just duration, but an imposed cutoff. It’s commonly used in formal, administrative, academic, and workplace contexts: government notices, school assignments, contract clauses, and official instructions.

This term carries a sense of authority and urgency; it implies consequences if the time limit is missed. Unlike more casual expressions like 截止时间 (jiézhǐ shíjiān), 限期 often appears in directives ('You must submit by X date') rather than neutral statements. It frequently co-occurs with verbs like 规定 (guīdìng, 'to stipulate'), 设定 (shèdìng, 'to set'), or 到期 (dàoqī, 'to expire'), and may be modified by numerals or time phrases (e.g., 限期三天, 'a three-day deadline').
