Everyone knows this, yet in this article, we will cover more: weekends, weekdays, origins, why the first day of the week is different in different parts of the world, the order of the seven days, and their translations in popular languages.
The seven-day week, a unit of time consisting of 7 consecutive days, is a practical division of time. It effectively divides the month into manageable periods and is the standard period used in calendars, aiding in planning and organization.
Weekdays are the days of the week that are typically considered working days. In general, there are five weekdays, or workdays, and these are Monday, Tuesday, Wednesday, Thursday, and Friday.
The weekend, which includes Saturday and Sunday, is a much-needed break from the typical workweek. It is a time for relaxation, leisure, and rejuvenation, balancing the weekdays.

Where do the names of the seven weekdays come from?
The names of the seven days of the week come from ancient Roman and Germanic cultures. They are named after the seven visible celestial bodies known to the ancient Romans.
Day of the week | Named after | Latin | Germanic |
Sunday | Sun | Dies Solis | |
Monday | Moon | Dies Lunae | |
Tuesday | Mars | Dies Martis | Tiw's day |
Wednesday | Mercury | Dies Mercurii | Woden's day |
Thursday | Jupiter | Dies Iovis | Thor's day |
Friday | Venus | Dies Veneris | Freya's day |
Saturday | Saturn | Dies Saturni |
The Greeks named the days of the week after the Sun, Moon, and five known planets, each named after a god: Ares, Hermes, Zeus, Aphrodite, and Cronus. The Greeks referred to the days of the week as Theon hemerai, or "days of the Gods". Mars, Mercury, Jupiter, Venus, and Saturn were the Roman gods who replaced the Greek gods. The Germanic people often substituted nearly identical gods for the Roman gods, Tiu, Woden, Thor, and Freya (Fria), but did not replace Saturn.
What is the origin of 7 days?
The origin of the seven-day week is not certain, but it is believed to have originated from the ancient Babylonians, who used a sexagesimal (base-60) system for mathematics and timekeeping. The seven-day week may have been influenced by the seven visible celestial bodies known to the ancient Babylonians.
What is the order of the 7 days of the week?
If we consider the ISO start of the week, then the order of the seven days of the week is Monday, Tuesday, Wednesday, Thursday, Friday, Saturday, and Sunday.
Otherwise, if we consider the US standard, then the order will be Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, and Saturday.
