משנה אויף במדבר 28:11

On Hanukkah they read the section of the princes (Numbers. On Purim, “And Amalek came” (Exodus 17:8). On Rosh Hodesh, “And on the first of your months” (Numbers 28:11). On Maamadot, the account of the creation (Genesis 1:1-2:3). On fast days, the blessings and curses (Leviticus 26:3 ff and Deuteronomy. They do not interrupt while reading the curses, but rather one reads them all. On Monday and Thursday and on Shabbat at minhah they read according to the regular order and this does not count as part of the reading [for the succeeding Shabbat]. As it says, “And Moshe declared to the children of Israel the appointed seasons of the Lord” (Leviticus 23:44) it is their mitzvah that each should be read in its appropriate time.
