十二星座是怎么来的

十二星座是什么，是怎么来的分享给大家。

十二星座希腊神话起源，星座起源于四大文明古国之一的古巴比伦，古代巴比伦人将天空分为许多区域，称为“星座”，不过那时星座的用处不多，被发现和命名的更少。黄道带上的12星座初开始就是用来计量时间的，而不像现在用来代表人的性格。

922年，国际天文学联合会大会决定将天空划分为88个星座，其名称基本依照历史上的名称。1928年，国际天文联合会正式公布了88个星座的名称。这88个星座分成3个天区，北半球29个，南半球47个，天赤道与黄道附近12个。

如同在东亚地区的一些民族根据出生年份所代表的动物来定义一个人的生肖，在很多国家，一个人的出生月份就以星座来对应。生日星座源于占星学，它试图利用人的出生地、出生时间和天体的位置来解释人的性格和命运。

出生月份与太阳星座的对应如下，由于天体运行的轨道与公历历法有差异，不同年份会前后相差1-2天，与中国农历的二十四节气各个“节”之间的距离吻合，节气时间的计算准确至分钟（并非子时开始），亦是星座的界线，每年均有差异。

白羊座 03月21日-04月19日 04月15日-05月15日 04月19日-05月13日 春分-谷雨前一天 金牛座 04月20日-05月20日 05月16日-06月15日 05月14日-06月19日 谷雨-小满前一天 双子座 05月21日-06月21日 06月16日-07月15日 06月20日-07月20日 小满-夏至前一天 巨蟹座 06月22日-07月22日 07月16日-08月15日 07月21日-08月09日 夏至-大暑前一天 狮子座 07月23日-08月22日 08月16日-09月15日 08月10日-09月15日 大暑-处暑前一天 座 08月23日-09月23日 09月16日-10月15日 09月16日-10月30日 处暑-秋分前一天 天秤座 09月24日-10月23日 10月16日-11月15日 10月31日-11月22日 秋分-霜降前一天 天蝎座 10月24日-11月21日 11月16日-12月15日 11月23日-11月29日 霜降-小雪前一天 蛇夫座 － － 11月30日-12月17日 － 射手座 11月22日-12月21日 12月16日-01月14日 12月18日-01月18日 小雪-冬至前一天 摩羯座 12月22日-01月19日 01月15日-02月14日 01月19日-02月15日 冬至-大寒前一天 水瓶座 01月20日-02月18日 02月15日-03月14日 02月16日-03月11日 大寒-雨水前一天 双鱼座 02月19日-03月20日 03月15日-04月14日 03月12日-04月18日 雨水-春分前一天 这只是时间表，12星座一般指的是黄道12星座（黄道带时间），即没有蛇夫座。因此，星座是按出生那年的公历（阳历）推算
