The names of the days of the week are so ingrained in our daily lives that we rarely stop to wonder where they actually come from. These familiar terms have deep historical roots that trace back thousands of years, intertwining mythology, astronomy, and ancient cultures.
Each day’s name reveals a fascinating story about how early civilizations understood time and the cosmos. Exploring these origins not only enriches our appreciation of language but also connects us with the beliefs and traditions of our ancestors.
From the Roman gods to Norse mythology, the etymology of the week’s days reflects a blend of cultures and celestial observations. Understanding these names offers insight into how ancient societies balanced their spiritual beliefs with the scientific knowledge of the stars and planets.
As you read on, you’ll discover how the names of the week are more than just labels—they are a legacy of humanity’s quest to measure and make sense of time itself.
Origins of the Seven-Day Week
The seven-day week has become a universal standard, but its origin is a fascinating tale of astronomy and culture. The choice of seven days is closely linked to the seven classical “planets” visible to the naked eye: the Sun, Moon, Mars, Mercury, Jupiter, Venus, and Saturn.
This system dates back to ancient Babylon, where astrologers observed these celestial bodies and assigned significance to each. The seven-day cycle was embraced by other civilizations, such as the Jews and Romans, eventually spreading worldwide.
Unlike months or years, which are based on natural cycles, the week is a human invention with cultural and religious significance.
The adoption of the seven-day week helped structure society and religious practices, influencing work, rest, and worship. The fact that this structure persists today is a testament to its practicality and deep historical roots.
“The seven-day week is a testament to the ancients’ fascination with the heavens and their desire to impose order on the passage of time.”
Sunday: The Day of the Sun
Sunday’s name is derived from the Sun, a celestial body that has held special importance in many cultures. It is traditionally considered the first day of the week in many parts of the world.
The term “Sunday” comes from Old English “Sunnandæg”, which literally means “Sun’s day.” This naming reflects the influence of Roman culture, where Sunday was dedicated to Sol, the Sun god. Many ancient societies worshipped the sun as a source of life and energy, which is reflected in the day’s name.
In Christianity, Sunday is particularly significant as a day of rest and worship, commemorating the resurrection of Jesus Christ. This religious importance helped solidify Sunday’s place as a day of rest in Western cultures.
- Originates from the Latin “dies Solis” meaning “day of the Sun”
- Associated with the Sun god in Roman mythology
- Religious significance in Christianity as the Lord’s Day
Modern Cultural Impact
Today, Sunday remains a day for relaxation and religious observance in many countries. The name continues to remind us of ancient connections to the Sun and its vital role in human life.
Even in secular contexts, Sunday often symbolizes a time of renewal and rest.
Monday: The Day of the Moon
Following Sunday, Monday is named after the Moon, highlighting the importance of this celestial body in early timekeeping. It is the second day of the week in many traditions and is linked to lunar cycles.
The term “Monday” originates from the Old English “Monandæg”, meaning “Moon’s day.” This reflects the Latin phrase “dies Lunae,” which also designates Monday as the day of the Moon. The Moon’s phases have long been used to mark the passage of time, influencing calendars and agricultural practices.
In various mythologies, the Moon is associated with femininity, mystery, and change, which adds layers of symbolism to the day’s name. Monday often carries a cultural connotation of new beginnings, as it starts the workweek for many.
- Derived from Old English and Latin terms referring to the Moon

The English word “Tuesday” comes from Old English “Tiwesdæg”, which means “Tiw’s day.” Tiw is the Anglo-Saxon equivalent of the Norse god Tyr. This naming corresponds with the Latin “dies Martis,” or “day of Mars,” the Roman god of war, showing how Roman and Norse traditions merged.
Tuesday is often associated with strength, conflict, and decisiveness, reflecting the martial attributes of its namesake gods. It marks a day of action and effort in many cultural contexts.
