PHP
日付操作

DatePriodが優秀なので、こんな感じで簡単に取得できます。
日毎の配列も作成できますし、範囲の指定方法もDatetimeを操作するだけなので、便利ですね！

qiita.php

$datePeriod = (new DatePeriod(
    new DateTime('2021/01/01'),
    new DateInterval('P1M'),
    new DateTime('2022/01/01'),
));

foreach ($datePeriod as $dt) {
     echo $dt->format('Y/m')."\n";
}
//出力結果
//2021/01
//2021/02
//2021/03
//2021/04
//2021/05
//2021/06
//2021/07
//2021/08
//2021/09
//2021/10
//2021/11
//2021/12
