128. When We Don’t Say Tashlumin

21:7 If someone erred in the Rosh Chodesh mincha and didn't say ya’aleh v’yavo when the next day is not also Rosh Chodesh, there’s no point in saying a compensatory prayer at maariv since he still won’t be saying ya’aleh v’yavo. (The Mishnah Brurah disagrees – MB 108:33.)

21:8 The musaf service can be said the entire day so the time for its compensatory prayer would logically be at maariv. However, there is no tashlumin for a missed musaf at night because the musaf prayers were instituted in lieu of sacrifices. If their time passed, there was no make-up period.
