You try not to have observant Jews or Muslims on the 3 to 11 shift because they need both Friday and Saturday off every week, and that creates tensions. Other religions have other requirements, so none of them is easy.

It was a lot easier in the military as you worked your assigned shift unless you used vacation time that was approved in advance.

That calendar system sounds like a much better deal than having to buy the various calendars every year, which didn’t start in January in most cases.

Many of my friends and colleagues (especially musicians) are Jewish, and I lived with a Jewish woman in grad school. When I saw that Mozilla Lightning, the calendar add-on for Thunderbird, has a Jewish calendar among its dozens of calendars available (like the add-on itself) for free, I thought, “Ah… a chance for me to learn more about Judaism.”

Well, yes, it was, and I do keep it installed… but disabled. It is almost literally true that every single date has some commemorative event on it, not just the major holy days. Having that much (forgive me) clutter on my daily calendar was just too much!
