The Lord spoke to Moses, saying: Say to the Israelite people:
On the fifteenth day of this seventh month there shall be the Feast of Booths to the Lord, [to last] seven days. The first day shall be a sacred occasion: you shall not work at your occupations; seven days you shall bring offerings by fire to the Lord. On the eighth day you shall observe a sacred occasion and bring an offering by fire to the Lord; it is a solemn gathering: you shall not work at your occupations.
Those are the set times of the Lord that you shall celebrate as sacred occasions, bringing offerings by fire to the Lord–burnt offerings, meal offerings, sacrifices, and libations, on each day what is proper to it–apart from the sabbaths of the Lord, and apart from your gifts and from all your votive offerings and from all your freewill offerings that you give to the Lord.
So Moses declared to the Israelites the set times of the Lord.
