On [the eighth day of] Chanukah [we read the portion of] the princes. On Purim [we read the portion of] And Amalek came. On Rosh Chodesh [we read the portion of] On your New Moons. On maamados [we read the portion of] the Creation. On [public] fasts [we read the portion of the] blessings and curses.  We may not interrupt [the reading of] the curses; therefore, one [person] reads them in their entirety.  On Mondays, Thursdays, and at Minchah on the Sabbath we read the regular order [of portions], but this [reading] is not taken into account.  As it is said, And Moses declared the appointed seasons of Hashem to the children of Israel —- the precept is that each [portion] should be read at the appropriate time.
