#sukkot begins on the 15th day of Tishrei and lasts for seven days, but the next day--the eighth day--is also special. God commanded us to rejoice before him for the entire week (Oh, what a burden!), but to set apart the first and eighth days especially for rest and gathering together in his name. Like Passover and Shavuot/Pentecost, Sukkot is a feast of YHWH. It's not just a Jewish holiday and it has no expiration date. It is "a statute forever."
