Friday and Saturday are the weekend.<p>That might just be a factoid, except that the Jewish Sabbath was the origin of the weekend concept. It changed in countries with a strong Christian influence so that Monday because the first day.<p>It never changed in the US because the Jewish workweek had a stronger influence there than the Christian one.<p>&gt; I personally detest calendars which display Sunday as the first day of the week<p>And I personally find calendars that start on Monday quite bizarre since it&#x27;s obviously incorrect historically.
