Etymology

Origin of out-of-date

First recorded in 1620–30

Explanation

Something that's out-of-date is either old-fashioned or so old that it's invalid. That typewriter in your closet is out-of-date, as well as that acid wash denim vest. An expired driver's license is out-of-date, and the out-of-date milk in your refrigerator is pretty likely to smell sour (depending on how out-of-date it is). Another way to be out-of-date is to be hopelessly unfashionable, like your mom's out-of-date bell bottom jeans or your grandparents' out-of-date kitchen, with its appliances from 1970. You can also use the words obsolete or outdated to mean out-of-date.
