星期又作週或者礼拜，是一个时间单位，每星期有7日。中國古代七曜一詞，起源於先秦時代的天文占星學，又稱七政；漢朝的數學家劉洪著作七曜術講述天文算學，《後漢書志二律历》:「正月甲子朔旦冬至，七曜之起，始於牛初。」；東晉范甯的《春秋穀梁傳序》：“陰陽為之愆度，七曜爲之盈縮。”疏：“謂之七曜者，日月五星皆照天下，故謂之曜。”五星指火、水、木、金、土。在唐代以前還未有使用七星指代輪回的7日或一週；古巴比伦人首先使用7日為一週的时间单位，后来犹太人把它传到古埃及，又由古埃及传到罗马，公元3世纪以后，就广泛地传播到欧洲各国。唐朝时期在西域和中国的交流中传入了中土獲得發展，再传入朝鮮半島、日本。光緒三十一年（1905年）由袁嘉穀所定用「星期」代替「曜日」，到了民国以後星期被廣泛使用。
