Origins of the seven-day week

The concept of a seven-day week has ancient origins, tracing back to the Babylonians around 1500 BCE. The Babylonians, keen astronomers, divided their lunar cycle into four weeks of seven days each, aligning with the phases of the moon. This practice was later adopted by the ancient Greeks and Romans, who found the seven-day cycle practical and meaningful.

The ancient Hebrews' influence also played a crucial role in establishing the seven-day week. According to the biblical account of creation, God created the world in six days and rested on the seventh, establishing a divine precedent for a seven-day cycle. This tradition was deeply ingrained in Hebrew culture and religious practices.

By the 1st century CE, the Romans had formalized the seven-day week, integrating it into their calendar system. This structure, combining astronomical observations and religious traditions, eventually spread throughout the Roman Empire and beyond, becoming the foundation of the modern seven-day week we use today.

In the Arabic and Hebrew calendars, the day begins at sunset, which contrasts with the Swahili concept of the day starting at sunrise and the Western world, where the day starts at midnight. This highlights the cultural influences on how days are numbered and identified within these different calendrical systems.

Origins of days of the week

How did Monday get its name? Meaning of Monday

Monday is named after the Moon. The Old English word for Monday was ѴDzԲԻæ, which translates to "Moon's day". This naming convention is quite common across various languages; for instance, in Latin, it's dies Lunae, also meaning "day of the Moon".

Tuesday name origin

Tuesday is named after the Norse god (also known as Tyr), a god of war and sky. The Old English term վɱæ directly reflects this association. The connection to Mars, the Roman god of war, can also be seen in other languages, such as French (mardi).

Why is Wednesday called Wednesday?

Wednesday is named after (or Woden), the chief god in Norse mythology. The Old English ´ǻԱæ translates to "Woden's day". This day is associated with Mercury in Roman mythology, which is why it's called éDZ in Spanish and mercredi in French.

Thursday name meaning

Thursday is named in honor of , the Norse god of thunder. The term 'Thor's day' serves as the etymological basis for Thursday. In Old English, it was Þū԰æ (Thunor’s day). The link to Jupiter, the Roman king of gods and god of thunder, explains the name jeudi in French and jueves in Spanish.

Friday history and meaning

Friday is named after (also known as Frigga or Freya), the Norse goddess associated with love and beauty. The Old English term æ means "Frigg's day". In Roman mythology, this day is linked to Venus, the goddess of love, which is reflected in names like viernes in Spanish and vendredi in French.

Saturday name origin

Saturday is unique among the English day names as it retains its Roman origin, specifically named after the Roman god , the Roman god of wealth and time. The Old English æٱԱæ directly references this deity. Interestingly, in other Germanic languages, the name often refers to the Sabbath, such as Samstag in German.

Sunday - The sun's day

Sunday is named after the Sun. Icelandic uniquely retains 'only the Sun' as the name for Sunday, rejecting names derived from pagan gods. The Old English ܲԲԲԻæ translates to “Sun’s day”, reflecting its importance and reverence in various cultures. This name is consistent across many languages, highlighting the widespread significance of the Sun.

The importance of understanding day names etymology

Understanding the etymology of day names helps language learners grasp the historical context and deepens their appreciation of English. These names are more than just labels for days; they are windows into ancient beliefs, cultures and linguistic evolution. The influence of Greek and Latin names on the naming of the days of the week during the Greco-Roman tradition is particularly notable, as the classical planets from Hellenistic astrology played a significant role in this process.

Exploring the origins of the day names in English reveals a blend of mythology, history and language evolution. From the Moon to Norse gods to Roman deities, each name tells a story of cultural significance.

    5 of the strangest English phrases explained

    By Steffanie Zazulak

    Here, we look at what some of the strangest English phrases mean – and reveal their origins…

    Bite the bullet

    Biting a bullet? What a strange thing to do! This phrase means you’re going to force yourself to do something unpleasant or deal with a difficult situation. Historically, it derives from the 19th century when a patient or soldier would clench a bullet between their teeth to cope with the extreme pain of surgery without anesthetic. A similar phrase with a similar meaning, “chew a bullet”, dates to the late 18th century.

    Use it: “I don’t really want to exercise today, but I’ll bite the bullet and go for a run.”

    Pigs might fly

    We all know that pigs can’t fly, so people use this expression to describe something that is almost certain never to happen. It is said that this phrase has been in use since the 1600s, but why pigs? An early version of the succinct “pigs might fly” was “pigs fly with their tails forward”, which is first found in a list of proverbs in the 1616 edition of John Withals’s English-Latin dictionary, A Shorte Dictionarie for Yonge Begynners: “Pigs fly in the ayre with their tayles forward.” Other creatures have been previously cited in similar phrases – “snails may fly”, “cows might fly”, etc, but it is pigs that have stood the test of time as the favored image of an animal that is particularly unsuited to flight! This phrase is also often used as a sarcastic response to mock someone’s credulity.

    Use it: “I might clean my bedroom tomorrow.” – “Yes, and pigs might fly.”

    Bob’s your uncle

    Even if you don’t have an uncle called Bob, you might still hear this idiom! Its origin comes from when Arthur Balfour was unexpectedly promoted to Chief Secretary for Ireland by the Prime Minister of Britain, Lord Salisbury, in 1900. Salisbury was Arthur Balfour’s uncle (possibly his reason for getting the job!) – and his first name was Robert. This phrase is used when something is accomplished or successful – an alternative to “…and that’s that”.

    Use it: “You’re looking for the station? Take a left, then the first right and Bob’s your uncle – you’re there!”

    Dead ringer

    This phrase commonly refers to something that seems to be a copy of something – mainly if someone looks like another person. The often-repeated story about the origin of this phrase is that many years ago, people were sometimes buried alive because they were presumed dead – when actually they were still alive. To prevent deaths by premature burial, a piece of string would supposedly be tied to the finger of someone being buried – and the other end would be attached to a bell above ground. If the person woke up, they would ring the bell – and the “dead” ringer would emerge looking exactly like someone buried only a few hours ago! Other stories point to the practice of replacing slower horses with faster horses – “ringers”. In this case, “dead” means “exact”.

    Use it: “That guy over there is a dead ringer for my ex-boyfriend.”

    Off the back of a lorry

    This is a way of saying that something was acquired that is probably stolen, or someone is selling something that’s stolen or illegitimate. It can also be used humorously to emphasize that something you bought was so cheap that it must have been stolen! “Lorry” is the British version – in the US, things fall off the back of “trucks”. An early printed version of this saying came surprisingly late in The Times in 1968. However, there are many anecdotal reports of the phrase in the UK from much earlier than that, and it is likely to date back to at least World War II. It’s just the sort of language that those who peddled illegal goods during and after WWII would have used.

    Use it: “I can’t believe these shoes were so cheap – they must have fallen off the back of a lorry.”
