Many Kmart stores are open from 8 a.m. to 10 p.m. Monday through Saturday, and 8 a.m. to 9 p.m. on Sunday. There is some variation in hours, an example being that some stores open at 7 a.m., and others close at 9 p.m. Monday through Saturday.
While these hours tend to serve as a guideline, some Kmart stores, such as the South Burlington, Vermont location, are open 24 hours per day. Other stores, such as the Salt Lake City, Utah location, close as early as 6 p.m. Monday through Friday, 3 p.m. on Saturday, and remains closed on Sunday. It is also important to consider that the store front may be open at certain hours when some of its features, such as a drive-through, are not.
