Reply To: Sunday: First Day of the Week or Seventh?

I don’t know if I would call it miraculous, but no doubt some people would. Many civilizations have, had, or proposed a week of more or less than 7 days. Examples that come to mind are Stalin’s Russia (both 5 and 6 day weeks), and the Tang dynasty (10 day week). This would make life exceedingly complicated for Shabbos observers, so it is wonderful that this is not an issue.
