Why our calendar is divided into seven-day increments
In short: The seven-day week is a global standard, yet its origins remain somewhat mysterious. This video explores how ancient lunar cycles may have shaped the way we measure time today.
The origins of the seven-day week are linked to two of the earliest known civilizations to use it: the Babylonians and the Jews. While direct evidence is scarce, scholars suggest the system may have emerged from observing the moon's phases. Each notable stage of the lunar month—from the first visible crescent to the full moon—occurs approximately every seven days.
