Also 24/7. Indication that something—a store, a service, a person—is available at all times (twenty-four hours a day, seven days a week). Used since the second half of the 1900s, at first for shops that never close, the term was soon applied in numerous other contexts. For example, “I’m not looking to get a knife in my chest. I’ve got twenty-four/seven protection on me” (David Baldacci, Hour Game, 2004). A theater review by Ed Siegel in the Boston Globe (Feb. 1, 2005) also had it: “The younger generation. What are we to do with them, with their ‘whatever’ attitude, their irony, and their 24/7 access to sex, drugs, rock’n’roll, and the Internet?” See also whatever.
