I just set my Google calendar to start each week on a Monday. I now prefer calendars that end the week with, well, weekends. I also set the little calendar on the Windows 10 task bar to default to that format.It simply seems more logical as that's how a hypothetical week runs in my mind. I have come to this realization long after giving up work weeks. More precisely, I've given up working all together.
I think the silliest calendar format puts Sundays on the left and Saturdays on the far right-hand side. That essentially breaks up each weekend. How silly is that!
This calendar returned from Sri Lanka with us this year. That's where we were for the New Year. It came back in the luggage.
