最近，有一部由雷佳音和易烊千玺领衔主演的古装悬疑剧?《长安十二时辰》?，据说豆瓣评分还挺高，这部改编自马伯庸的同名小说的剧，听名字跟时间有不少关系呢！
它的英文译名是The Longest Day in Chang’an，而不是24 Hours in Chang’an，为什么呢？因为hour无法体现古代中国“时辰”的概念。说到“时辰”，今天我们就来看看在英语的“时辰”应该怎么说？
one of the 12 two-hour periods into which the day was traditionally divided, each being given the name of one of the 12 Earthly Branches（地支）.
古代人把一天划分为十二个时辰，每个时辰相等于现在的两小时。

(early) morning?清晨；早晨；午夜至正午的时间
