Resolved: time zones, leap years, leap seconds, and solar timekeeping should be abolished

Here’s a previous thread on the seven-day week (a blast from the past).

About seven-day week

Hi guys, I am a bit curious about the seven-day week. Who first invented it and who decided which day was Sunday etc? Is there any record of it? Has there been any adjustment in history (like the day-of-year adjustment when we shifted from Julian to Gregorian Calendar) I guess it has some religious link, so how did people make sure that the sabbath people use today is actually the day of rest ordered by God?
