Also known as months

時間的單位

AI overview

A month is a unit of time used in calendars that is roughly based on the Moon's natural cycle, which lasts about 29.53 days—this is why the words "month" and "Moon" are related. Months matter because they provide a practical way to organize time into manageable periods, a practice that humans have used since at least the Paleolithic age when people tracked days according to the Moon's phases.

月是一個時間單位，在與日曆一起使用時，大約與月球的自然軌道週期一樣長；單詞“month”和“Moon”是同源。傳統的概念隨著月相的週期而出現；這樣的太陰月（“lunations”）是朔望月，持續約29.53日。從出土的中，研究人員推斷，人類早在舊石器時代就根據月相來計算日期（天數）。基於月球相對於地球-太陽軌道週期的朔望月仍然是當今許多曆法的基礎，並用於劃分年。中国的农历一年通常为12个月，闰年为13个月，多出的一个月称为闰月。
