when do factories close for chinese new year Factories in China typically close for Chinese New Year celebrations, which usually fall between late January and February, depending on the lunar calendar. The holiday period can last from one to two weeks, with many factories closing for at least a week. During this time, production may halt or slow down, and workers travel to their hometowns for family reunions. Businesses should plan accordingly and place orders well in advance of the holiday season to avoid delays.
