Yosef Karo

“ On the seventh day, the first reading is "On the fifth day," the second is "On the sixth day," The third is "On the "On the seventh day," and the fourth is "On the sixth day...and on the seventh day." This is our practice (Rash"i in the name of his teachers, Mahari"v, Minhagim) . In Israel where there is no doubt about the day, they only read the sacrifice of the day. On the second day, which is the first day of Hol Hamoed, the first reading is "On the second day" and the three next readers read the same section. ”
