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 Monandæg, 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 Tiw (also known as Tyr), a god of war and sky. The Old English term Tiwesdæg 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 Odin (or Woden), the chief god in Norse mythology. The Old English Wodnesdæg translates to "Woden's day". This day is associated with Mercury in Roman mythology, which is why it's called miércoles in Spanish and mercredi in French.

Thursday name meaning

Thursday is named in honor of Thor, the Norse god of thunder. The term 'Thor's day' serves as the etymological basis for Thursday. In Old English, it was Þūnresdæg (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 Frigg (also known as Frigga or Freya), the Norse goddess associated with love and beauty. The Old English term Frigedæg 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 Saturn, the Roman god of wealth and time. The Old English Sæternesdæg 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 Sunnandæg 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.

    Funny literal translations from around the world

    By Charlotte Guest
    Reading time: 3 minutes

    One of the fun things about learning a new language is discovering how different cultures describe everyday objects and concepts. Sometimes, these descriptions are so literal and imaginative that they bring a smile to our faces (and maybe a few confused looks). Here are some examples of words in other languages that, when translated literally, are probably not what you expected.

    Four motivating activities to teach core values through reading

    By Nicola Schofield
    Reading time: 4 minutes

    Teaching our children core values is so important in helping them to become happy, well-balanced citizens who will make a positive contribution to our future society. 

    Values are present and visible everywhere and they are the foundation or starting point from where we make our decisions, which ultimately determine our futures. It is, therefore, important that our children learn a strong, moral set of values that will help guide them as they grow older, inform their decisions, help them to know right from wrong, solve problems, assert themselves and build self-esteem and confidence.

    Values can be built on a personal level or even shared at a group level such as a family and friendship group. However, we often see them on a larger scale within communities, countries or even the whole world. 

    Having a shared set of values connects people on a deeper level and helps us to all work towards the same goals and standards – they can even encourage people to see the similarities between each other, rather than the differences. 

    Learning values through reading

    Children learn about values through their families, friends, and teachers, through what they watch or listen to and through their life experiences. They also learn about values through the books they read. These lessons can be subtle but are often extremely powerful and can have a significant impact and influence.

    As an example, let’s have a look at how shared values are explored in the new graded readers series for young learners, Disney Kids Readers, where special emphasis has been put on exploring values within a story. At the end, you will find several value-based activities that you can download for use in the classroom or as an activity at home. 

    How do Disney Kids Readers teach core values?

    1. Learning through stories that are already familiar can help children to trust in and take on board the key messages much more easily. Familiarity can break down many barriers to communication and help us understand that values are often universal. 
    2. Many children are also familiar with the Disney characters and can find inspiration from reading how they react to situations in life, make decisions and behave. Children often look up to characters and can see them as role models within their own lives. As a result, the readers can be a reference point on how to respond to key life moments and how to incorporate values into real life.
    3. Also, depending on the child's age, some values may be new and children may not yet have experience with them in the real world. Therefore, the Disney stories allow them to explore these key messages through their favorite Disney character’s point of view. 

    Each Disney Kids Reader is linked to a key value and contains a ‘Values’ page with a short comic strip that brings to life a specific value. 

    The list below details a selection of key values taught across the readers. You could ask the children in your class to talk about which values are most important to them and why. Ask them to give an example of a time when they have demonstrated this value in their own lives. 

    Friendship, positivity, curiosity, confidence, open-mindedness, courage, determination, self-belief, responsibility, resilience, respect, honesty.

    Examples of key values in Disney stories

    In The Jungle Bookfriendship is a key value, and we learn that it is important to help our friends. Baloo helps Mowgli when he is alone in the jungle and scared. An angry tiger wants Mowgli to leave the jungle, but when Mowgli meets Baloo, he finds a friend in him. Baloo sees that Mowgli is scared and looks after him. We learn that it is important to help our friends when they are in need. 

    Do: Ask the children when they have helped their friends.

    In Inside Out, we learn about sincerity and how important it is to talk about how we are feeling. Riley is a teenager struggling with a whole range of emotions and we learn that life isn’t about being happy all the time and that it is okay to be sad sometimes. The children learn that this is a normal part of life and that talking it through with a friend, a parent or a teacher can help.

    Do: Ask the children if they share their feelings with others.

    Here are some activities for you to use with your class to help put into practice the core values from the readers. You can use these activities with any book, in and outside the classroom.

    1. My Values Road Sign (L3-4)

    This activity is a great way of talking to children about their values. By creating a road sign poster, it will help them to decide which values are most important to them and it is something that they can refer to again and again in challenging times. They can stick it on their bedroom wall, display it on the fridge or you could even make a classroom display of shared values when children have finished their books!

     2. Kindness Calendar (L4-6)

    This activity can be done as a family, with friends or as a class. The children fill in the calendar with kind actions they are going to do for 7 days. They can cut them out and place them into a jar and ask a different family member/friend/classmate to choose one a day. Do this for a week and discuss how carrying out kind actions makes them feel. Chances are it will make them feel good!

    3. Core Values Quiz (L5-6)

    Try this quiz with your class and test their values. The questions focus on the following values: sincerity, honesty, positivity, resilience and friendship. If they answer mostly As, then they already demonstrate most of the values in their lives. If they answer mostly Bs, talk to them about why it is important to be honest, positive, strong and kind. The quiz will start a meaningful conversation about their own values and how they react to common situations in life.

    4. My future self (L1-2)

    The children fill in the crystal ball with pictures of who they would like to be in the future. Do they want to be smart, funny, have a good job, live abroad, have a family, be rich, be a good friend or help the planet? Which of the plans make one person (themselves) happy and which plans make the world better? Do they need to change any of them?

    Enhancing workplace communication: The new role of language assessments in business success

    By Andrew Khan

    The integration of AI tools into workplaces around the world is starting to change the way people communicate professionally. Research suggests that the use of AI to help draft documents and emails is driven not only by convenience and efficiency but also by a desire to be clear and precise in language.

    While potentially useful, tools to translate, generate, or ‘correct’ written text won’t help with the effectiveness of the verbal communication that powers business relationships.
