The Complete Guide to the English Days of the Week [Vocabulary, Expressions and Tips]

Talking about the days of the week in English seems simple, but getting it wrong can cause some serious scheduling confusion.

In this post, we’ll give you tips for memorizing and correctly using each day of the week in English.

We’ll also show you essential expressions related to days of the week.


In many languages, the days of the week come from the names of the planets or the ancient gods that represented them. This is the case in English, which follows the Germanic names for these gods.

The etymologies (word origins) for all words below are based on this Live Science article and confirmed with the Merriam-Webster dictionary.

Monday: The Moon Day

Monday is the day of the moon god. In Old English, mōna was the name for the moon, and from this we get the name Monday.

In English, you might hear people talking about a “Monday morning feeling.” This is a popular idiom that means being downhearted about starting a new workweek.

You may also hear someone tell you that they have the “Monday morning blues.” Again, this means that they feel tired or annoyed about having to get up early and go back to work. You might want to offer them a cup of coffee!

On a calendar, you may see Monday abbreviated to “Mon.” This is useful when you’re writing it down, but it sounds strange when you say it aloud. In conversation, be sure to stick to the full name for each day of the week.

Tuesday: The Day of War

In Ancient Rome, this day of the week was named after Mars, the god of war. This is how we get mardi in French or martes in Spanish. But in English, the name comes from the Norse god Tyr (also spelled Tiw or Tiu).

If somebody warns you that you can say something “from here to next Tuesday,” they mean that even if you keep repeating yourself, the person you’re talking to won’t listen. For example, “You can tell Max from here to next Tuesday that he needs to wash his car, but he isn’t going to do it.”

Tuesday can be abbreviated to Tu., Tue. and Tues. Again, these abbreviations are only used in writing.

Wednesday: The Day of Wisdom

This word is out to trick everybody. Even native English speakers find it strange.

Rather than being pronounced “Wed-nes-day,” as the spelling suggests, it’s actually pronounced “wens-day.”

It’s probably the hardest English day of the week to remember, because most languages name this day after the Roman god Mercury. You might expect it to begin with an “m” like mercoledì in Italian or mercredi in French.

However, in English, this day is named after Woden, the Norse god of wisdom. You can use this to help you remember because “wise” and “Wednesday” begin with the same letter.

Sometimes English speakers will refer to Wednesday as “Hump Day.” This is a common piece of slang that refers to Wednesday being the “hump” or the middle point of the workweek. For example, somebody might say, “It’s Hump Day again, but that means we’re closer to the weekend.”

In diaries and calendars, you’ll see Wednesday abbreviated to Wed.

Thursday: The Day of Thunder

If you’ve seen any of the Marvel “Avengers” films, you’ll be familiar with the superhero Thor and his magic hammer. He’s the super-strong Norse god of thunder, and also where we get the word “Thursday” from. Originally, it would’ve meant “Thor’s day.”

A popular hashtag that English speakers use on Instagram is #throwbackthursday. In English, a “throwback” reminds you of something that happened in your past, so this hashtag is used to share memories such as holiday photos or baby pictures.

There are a few ways of shortening the word Thursday. You can use just the first two or three letters, but it’s most commonly written as Thurs.

Friday: The Day of Love

Everyone loves Friday.

It’s a chance to unwind after a week of work, to go out with friends or to spend time with family. It seems appropriate that in English it’s named after the Norse goddess Frigg, who represented love, marriage and wisdom.

“That Friday feeling” is a popular English expression. Unlike “Monday morning blues,” it means feeling excited about the end of the workweek. “Get that Friday feeling” is a phrase you may encounter in advertisements, meaning that a product is supposed to make you feel the same sense of happiness and anticipation as you would before the weekend.

You’ll usually see the word Friday abbreviated as Fri. in writing.

Saturday and Sunday: The Weekend Is Here!

There are seven days of the week, but there are only five “weekdays.” This word refers to the five days we’ve already covered, when most people are at work or studying.

For the majority of us, Saturday and Sunday are the most important days of the week! They’re referred to separately as “the weekend.”

Saturday is named after the Roman god Saturn, but Sunday is easy to remember. It simply means the day of the sun. The written abbreviations are also pleasingly easy: Sat. and Sun.

In English, there are plenty of idioms that use these words.

If somebody asks you to come dressed in your “Sunday best,” they want you to wear your nicest clothes, because traditionally that’s what you’d wear if you went to church on Sunday. If someone talks about a “long weekend,” they mean not going to work on Friday or Monday, and having a short holiday.

Perhaps one of the weirdest English expressions you’ll hear is, “it will never happen in a month of Sundays.” This means that something is never, ever going to happen, so you probably shouldn’t hope for it.

How to Practice Using the English Days of the Week

Using the English days of the week might take some getting used to. The best way to learn is always through practice, so you can start by organizing your own calendar or diary using the English words.

Some people prefer to plan on paper, but there are plenty of websites in English that’ll help you create a timetable yourself. If you’re a student, consider using platforms like Any.do or MyStudyLife, which let you organize your calendar and make to-do lists.

This is a great way to integrate new vocabulary into your daily life while making English practice a part of your routine. It’ll also prepare you for life in an English-speaking country, where knowing the days of the week (and their abbreviations) is an important skill for managing your time.

Master these practical English words and phrases about the days of the week, and your confidence will begin to grow and grow!
