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 STEAM myths debunked

    By Sarah Hillyard
    Reading time: 4 minutes

    STEAM (Science, Technology, Engineering, Art and Maths) sounds like an overwhelming combination of subjects to teach – and only suitable for expert educators. But the reality is doing STEAM is simpler than you think. Here are 5 common STEAM myths and the truth behind them. We also outline a number of simple activities you try with your students.

    1. STEAM requires a lot of time

    STEAM projects encourage curiosity, creativity and collaboration in the classroom – but they have a reputation for being preparation-heavy and for requiring a lot of teaching time and energy.

    But to get the full benefit of STEAM, there’s no need to plan out a full-blown project that lasts a whole month. In fact, you might integrate just one STEAM lesson into your syllabus. Or a lesson could contain a one-off 10-minute STEAM challenge.

    Here are some easy, low-preparation challenges your classes can take part in:

    10-minute STEAM challenges:

    • Winter unit: How tall can you build a snowman using paper cups?
    • Shapes theme: Using five toothpicks make a pentagon, two triangles, a letter of the alphabet.
    • Bug project: Can you create a symmetrical butterfly?

    2. You need fancy materials to do STEAM

    The biggest misconception is around technology. When you think of STEAM, you might imagine you need apps, computers, tablets and robots to teach it successfully. It’s true that you will certainly find STEAM challenges out there that involve extensive supply lists, expensive equipment, knowledge of programming and robotics.

    However, in reality, you probably have everything you need already. Technology doesn’t have to be expensive or complicated. It can refer to simple, non-electronic tools and machines, too. Think funnels, measuring cups and screwdrivers, for example. You can use low-cost regular classroom or household items and recyclable materials that learners' families can donate. Toilet paper rolls and cardboard boxes are very popular items in STEAM.

    Here is a low-tech activity you can try:

    Combine engineering, art and math using cardboard and a pair of scissors

    This challenge involves creating 3D self-portrait sculptures in the using only cardboard. First, teach about parts of the face by observing and analyzing some Cubist portraits (eg, explore Georges Braque and Pablo Picasso). Then have learners cut out cardboard shapes and make slits in them to attach together. They create their self-portrait sculptures by fitting the pieces together using the slits so that the final product will stand by itself. Display the self-portraits and talk about them.

    3. STEAM is targeted to older learners

    Young children are naturally curious about the world around them, and STEAM experiences begin very early in life. They explore with their senses and test their hypotheses about the world, just like scientists do. Much of their play is based on engineering skills, such as building houses with LEGO® bricks. They learn to manipulate tools while they develop their fine motor skills and their awareness of non-electronic technology. They use dramatic play and enjoy getting their hands full of paint while engaged in art. They learn about maths concepts very early on, such as size (big and small toys), quantities of things, and even babies start using the word “more” if they’re still hungry.

    Check out this simple STEAM experiment to learn about plants and their needs.

    How do plants eat and drink?

    Have students put water and food dye in a pot. Put a white flower in the water. Ask students to guess what will happen.

    After a few days, students should check their flowers and observe how it has changed color. They must then record their results. Extend the experiment by asking if they can make their flowers two colors.
