The origins of the names of the days

The names of the days are in some cases derived from Teutonic deities or, such as in Romance languages, from Roman deities. The early Romans, around the first century, used Saturday as the first day of the week. As the worshipping of the Sun increased, the Sun's day (Sunday) advanced from position of the second day to the first day of the week (and saturday became the seventh day).
「天」的名字，來自日耳曼神明或羅馬神明。早期羅馬人，大約一世紀左右，將星期六視為一星期的第一天。隨著對於太陽的崇拜增加，太陽的日子（星期天）從第二天的位置變成第一天。原本的Saturday變成第七天！
