noun
Usage
What does Monday mean? Monday is the weekday between Sunday and Tuesday.Many countries in North and South America, including the U.S. and Canada, consider the calendar week to begin on Sunday, with Monday being the second day of the week. In other places, including in much of Europe and Asia, Monday is considered the first day of the week. In parts of the Middle East and other places, the week is considered to begin on Saturday.Regardless of when the week officially begins, in many places Monday is considered the first day of the workweek, the five-day span during which many people work and that ends on Friday (with Saturday and Sunday considered the weekend).Since for many people Monday is the first workday (or school day) after the weekend, it is associated with a return to work and responsibilities. For this reason, and because Mondays have a tendency to be busy and hectic, it is often considered the most disliked day of the week (at least by Garfield, anyway).The phrase case of the Mondays is a humorous way of referring to the state of being grumpy or sluggish because it is a Monday. The slang term Mondaze (pronounced like Mondays) similarly refers to the daze you might find yourself in on a Monday.The word Mondays can be used as an adverb meaning every Monday or on Mondays, as in I work Mondays or Many restaurants are closed Mondays. To indicate the general time of day during which something will happen on a Monday, the word can be followed by the general time, as in Monday morning, Monday afternoon, Monday evening, and Monday night. Example: People hate Monday, but for me, the worst day of the week is Tuesday—it’s still days away from Friday without any of that recent weekend glow.
