What is a weekday?

A weekday is any day that is not a weekend day.

Since the weekend is considered to consist of Saturday and Sunday, the weekdays are Monday, Tuesday, Wednesday, Thursday, and Friday. (Even though Friday evening is sometimes considered the start of the weekend, Friday is still considered a weekday.)

The evenings of weekdays are called weeknights.

The word week most commonly refers to any period of seven consecutive days, or to the seven-day period on the calendar that begins on Sunday and ends on Saturday. However, in weekday and weeknight, it refers to the five-day period that’s often considered the workweek or school week. The standard workweek is from Monday through Friday, though working schedules vary widely. Days of the workweek can be called workdays. Weekdays are usually (but not always) workdays or school days.

For this reason, terms like weekday and weeknight are typically used—instead of just saying day or night—to distinguish them from the days and nights on the weekend.

The word weekdays can be used as an adverb meaning on weekdays—Monday through Friday. The word weekends can be used as an adverb in the same way, as in We’re open weekdays from 9 a.m. to 5 p.m., but we’re closed weekends.

Example: I don’t usually like to be out so late on a weekday, but I couldn’t miss this!

Where does weekday come from?

The first records of the word weekday come from before the 900s. The seven-day week dates back thousands of years, and the concept of the week being divided into working days and nonworking days is also very old. The seven-day week appears in the Biblical account of creation, which introduces the idea of a rest day.

If weekdays are workdays or school days for you, you probably have strong opinions about each one. People famously hate Mondays and love Fridays, with Wednesdays being seen as a hopeful halfway point to the weekend. Tuesday might be the worst weekday, though—it’s still days away from Friday without any of the leftover glow from the weekend. And Thursdays just wish they were Fridays.
