Historical Perspectives on the First Day of the Week
Ancient Civilizations and Their Calendars
Throughout history, different civilizations have adopted varying conventions for the week's start:
- Babylonians and the Sumerians:
The Babylonians, among the earliest known civilizations, used a seven-day week influenced by astronomical observations, especially planetary movements. They considered the week to be aligned with celestial bodies, with the number seven representing completeness.
- Ancient Egypt:
The Egyptians divided their calendar into ten-day weeks called "decades," but they also recognized a seven-day cycle linked to lunar phases.
- Ancient Hebrews:
The Jewish tradition, as documented in the Hebrew Bible, designates Sunday as the first day, with the week culminating in the Sabbath on Saturday. This structure has influenced religious and cultural calendars for millennia.
- Roman and Gregorian Calendars:
The Romans initially used an eight-day market cycle but later adopted the seven-day week from the Egyptians and Jews, with Sunday traditionally considered the first day in many Christian-influenced calendars.
Religious Influences on the Week's Start
Religious beliefs have profoundly shaped perceptions of the week's beginning:
- Judaism:
The Sabbath (Saturday) is the seventh day, with Sunday viewed as the first day of the week. This structure is rooted in biblical commandments and continues to influence Jewish and Christian calendars.
- Christianity:
Many Christian traditions consider Sunday as the first day, honoring the resurrection of Jesus Christ, which is believed to have occurred on a Sunday. The early Christian church adopted this convention, which persisted through centuries.
- Islam:
Muslims observe Friday as a day of congregational prayer (Jumu'ah). In Islamic tradition, the week begins on Saturday, with Friday being a special day, but the overall calendar varies regionally.
