注釈

このメソッドは、閏年と一般的な年の指定した月の日の別の数を返します。This method returns a different number of days in a specified month for a common year versus a leap year. たとえば、このメソッドを返します 29 または 30 閏年の (month = 12) かどうかに応じて、yearうるう年します。For example, this method returns 29 or 30 for Zulhijjah (month = 12), depending on whether year is a leap year.
