The seven-day week dates back to the time of Moses and the origin of the Torah, including the "Ten Commandments". One of the Ten Commandments is to remember that every seventh day, the Sabbath, is a holy day on which no work may be done.
Despite the sacrilege of Emperor Constantine of Rome, proclaiming the first day of the week, the day of the sun god, to be the day of rest instead of the seventh day, thanks to calendars the cycles of seven days have endured in many places like an unbroken chain through time for over five millennia.
