Costco believes that its employees need to spend time with their families and hence remains closed on certain Federal holidays. It’s generally not open to business on New Year’s Day, Easter, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day but remains open on Christmas Eve and New Year’s Eve. However, on these days, Costco closes earlier than usual – at 6:00 P.M. instead of the typical 8:30 P.M.
