Relating to a recent post:
Why does the Mishna say "בראש השנה בחדש השביעי באחד לחדש" whereas when talking about the readings on Pesach and Sukkos it is called פרשת המועדות. In fact it is the same reading!! [We can't read on Rosh Hashana JUST about Rish Hashana because there wouldn't be enough pesukim for 5 Aliyos].
