時間の単位

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（つき、がつ、げつ、英: month）は、時間の単位の一つ。年と日の中間にある単位で、一年を12分した日数である。現在世界で標準的に用いられるグレゴリオ暦は、修正元のユリウス暦の月を汲み、1か月の日数は30もしくは31日を基本とし、2月のみ通常（平年）は28日、400年間に97回ある閏年には29日としている。
