首先，“端”的意思就是“初”，所以五月初五也可以叫做五月端五，然后呢，按照地支的顺序推算，五月就是“午月”，五日就是“午日”，“端五就成了“端午"了。

First of all, "Duan" means "initial" or "start", so instead of saying the fifth day of the fifth lunar month using the customary phrase "五月初五", you can substitute "初" with "端" to give you "五月端五", and then, according to the order of the 12 earthly branches, May is referred to as "午月", while the fifth day of a month is referred to as "午日", which is how Duanwu Festival became Duanwu Festival.
