You know, if you think about it, it’s a good thing that when Pope Gregory skipped 10 days in 1582* to correct deficiencies in the Julian calendar, that he only skipped the calendar dates and not the actual days of the week. Otherwise, we’d be celebrating Shabbos in the middle of the work week. 🙂

* Thursday, Oct 4, 1582 was followed by Friday, October 15, 1582.
Wolf: If the story I heard was correct, they wanted to add an “Earth Day” between a Saturday and a Sunday one day in the 70s and one of the main reasons they didn’t was that it would make Shabbos on Friday from then on.
Also, imagine how tough it was for Jews under the French Revolution during the few years that they actually tried to make the 10-day week stick.
