Halakhah su Levitico 22:8

The commandment of resting on the seventh [day] of Pesach: To rest on the seventh day of Pesach, as it is stated (Leviticus 22:8), "and on the seventh day, a holy occasion." And I have already written above close by to this commandment (Sefer HaChinukh 297) that in every place in which it is stated in the Torah, "a holy occasion," its content is to say, make it holy, to not do work on it, and [that] it is a positive commandment. And a hint from the roots of the commandment from the angle of its simple understanding is also written there. And as is our custom, we will write a few of its laws with God's help in the negative commandment of the prohibition of work in this Order (Sefer HaChinukh 298). And the entire content of resting on the seventh [day] is like the rest of the first day. And they are both considered one festival with regards to that which we do not say [the blessing over] time (shehechiyanu) on the seventh; and so with every matter - which is not the case on Shemini Atseret, which is a holiday on its own (Yoma 2b), and as we will write in its place (Sefer HaChinukh 323), with God's help.
