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.

    Reaching exam success with happiness and wellbeing in mind

    By Sophia Fergus

    Are you or your students preparing for an exam like ? If so, you might find that things are more stressful than usual or that motivation is starting to lack. When preparing to take an exam, it’s easy to overlook the fact that people also need to destress and relax a little.

    Exam preparation is an important period. That’s why we’ve come up with some tips and advice that will help increase happiness and well-being. It will also help develop good study habits and ensure you or your students remain happy right up to their exams and beyond.

    1. Create a study plan

    A clear plan can help you get off to a positive start. At the same time, it will inevitably lead to more confidence and better results on the big day. Make sure to gather all the materials and equipment you will need (or provide your students with a list of what they need to gather). Once prepared, set up a comfortable workspace where you will feel happy to spend time. If you’re a teacher, you can ask your students to describe their ideal study spaces in class – this will help them visualize what they need to do at home!

    It's also helpful to create a schedule where you write down what you need to work on and when. Try to include all areas of the exam but prioritize those areas that may need more work and improvement.

    2. Take time out

    If you're starting to feel anxious or stressed as the exam day comes nearer, here are some ideas to help manage:

    Take a break

    It’s better to study for short periods rather than spending hours on end at their desk. It’s a good idea to break up study periods and take a short break at regular intervals. If possible, also go outside and get some fresh air at least once a day.

    Try mindfulness techniques

    Guided meditation apps such as or can help reduce stress and prepare learners to focus better on their studies. You can also find guided meditation videos and audio tracks on Youtube or Spotify.

    Be positive

    Remember how far you’ve progressed and celebrate what you can do, and if you’re an educator encourage them to visualize themselves confidently completing the exam.

    3. Have fun!

    Although exam practice and reviewing are important parts of preparing for an exam, you can also have some fun. Play games and base activities around a variety of different media, including short videos and podcasts and other forms of entertainment.

    Make English a part of your leisure time. Watch series or films in English, listen to music or choose podcasts related to your interests. A good tip is to look for English-language alternatives to any materials or media usually consumed.

    4. Stay healthy

    The stress caused by exams can result in bad habits, and eating unhealthily – fast food, snacks and caffeine can provide a false sense of energy. However, the food we eat and drink can greatly affect our body and mind. A healthy diet can improve our mood, our memory and our levels of concentration:

    • Healthy carbs such as brown rice, pasta, whole grain bread and cereals will provide the necessary energy to allow students to keep working through the day.
    • Oily fish like salmon and sardines are great for the brain, heart and joints, as well as increasing serotonin which makes us feel good!
    • Other sources of Omega 3 such as nuts and seeds are a great substitute for vegans.
    • A variety of fruits and vegetables will ensure that students have a balanced diet that will improve memory, brainpower and mental agility.

    5. Get a good night’s sleep

    Sleep is essential for learning to take place. The time you spend asleep is just as important as the time you spend awake. You should aim to sleep for 8 hours a night. This will help your brain to recharge, allowing you to start the day with energy and focus.

    It’s especially important that you sleep well the day before the exam. This will help you relax and ensure that you are alert and ready to give your best performance.

    6. Offer incentives

    If you are studying intensively or for a long time, motivation levels may start to drop. If you’re a teacher and you see this is the case, your class will need some additional support and encouragement to help them keep going. Small rewards can help with this.

    Teacher: You can offer rewards in class by allowing students to choose an activity they enjoy, but it’s also useful for students to give themselves rewards for any goals they set and accomplish. This personalization will make the reward even more satisfying.

    Self-learner: When you get to certain checkpoints of your study make sure to reward yourself with something small that you enjoy. Small rewards include things like listening to your favorite song, eating a sweet treat or watching a funny video.

    7. Reduce the workload

    As the exam approaches, make sure to gradually slow down. Rather than trying to learn something new, spend the last few days reviewing what you’ve studied and practice English as much as you can. On the day before the exam, do something completely different, like go for a long walk or watch a good film. Just to get your mind to wind down and relax before your exam, which will likely be quite demanding on the brain.
