Usage
What does Sunday mean? Sunday is the day between Saturday and Monday. In North and South America, most countries (including the U. S. and Canada) consider the calendar week to begin on Sunday, making it the first day of the week. In other places, including in much of Europe and Asia, the week is considered to begin on Monday, making Sunday the seventh and final day of the week. In parts of the Middle East and other places, the week is considered to begin on Saturday, making Sunday the second day of the week. Regardless of when the week officially begins, in many places Sunday is considered (along with Saturday) one of the two days that make up the weekend, during which many people do not work. In contrast, the other five days, Monday through Friday, are considered weekdays, which make up the workweek (or school week). In this sense, Sunday is not considered a weekday but a weekend day. Many people’s favorite day is Saturday because it’s the official start of the weekend, with another weekend day ahead of it—Sunday. Sunday is often enjoyed as a day of recreation and rest (some people call it Sunday Funday). But it comes with a catch: it’s followed by Monday, which is famously disliked due to being the first day of the workweek. (This feeling of dread over the weekend ending is sometimes called the Sunday scaries.)The word Sundays can be used as an adverb meaning every Sunday or on Sundays, as in I work Sundays or The shop is closed Sundays. To indicate the general time of day during which something will happen on a Sunday, the word can be followed by the general time, as in Sunday morning, Sunday afternoon, Sunday evening, and Sunday night. Example: Sundays are bittersweet—I like relaxing, but in the back of my mind I’m worrying about the coming workweek.
