次の制約により、請求書の日付を使用して期日を計算しようとしています

  • 2 つのテキスト ボックスがあり、1 つは日付を入力し、もう 1 つは期日の前日を入力します。

  • 毎月の日が 4 で、期日の前日が 5 の場合、減算された値が -ve 1 で、入力された請求日が 2016 年 11 月 13 日である場合、4 と 5 を減算して値を計算する必要があります。日付は 2017 年 4 月 12 日でなければなりません (ここで 04 は月の日です)

  • 毎月の日が 15 で、支払期日の前日が 5 で、減算値が 10 (負ではない) の場合、入力された請求日は 2016 年 11 月 13 日です。請求書の日付が差し引いた値以下、つまり請求書の日付が 11/09/2016 のように 10 の場合、請求書の日付は 2016 年 11 月 15 日である必要があります。

上記の制約は、燃料の日付を計算する際にうるう年も満たさなければならないことに注意してください
