ATTENTION NON-JEWS OF TWITTER:

Here is a thread of super important Jewish days coming up that, if you are in charge of scheduling things, you should definitely avoid - assuming, of course, you want to be thoughtful for your Jewish friends and co-workers.

Rosh HaShanah, the Jewish New Year, begins Friday evening, September 18 and ends Sunday night, September 20.

Avoid scheduling things on those days entirely.

Many Jews will use the days before to prepare, so please be light in scheduling for that Wednesday & Thursday, too.

Yom Kippur, the holiest day on the Jewish calendar, begins Sunday evening, September 27, and continues through late Monday evening, September 28.

Please don't schedule anything for that Sunday or Monday at all. This is the biggest deal and the most important for most folks.

Sukkot, the holiday where we build huts and spend far too much time outside, begins Friday evening, October 2 and continues (broadly speaking) through Sunday night, October 11.

Definitely avoid scheduling from Friday-Sunday of each of those weekends.

Many observant Jews will fill their weekdays with celebratory meals and events, too. While it is ok for most folks to work those days, evenings will be pretty booked up observing the holiday.

Also, TEACHERS! These are days you should avoid homework assignments, and definitely don't schedule a test for the day or two after.

ALSO! If you're in charge of scheduling and you're not sure if you're choosing proper dates for your folks? ASK THEM!

Plenty of folks aren't so observant and they won't mind, but plenty of folks are and they will mind. You can't go wrong asking what everyone prefers.

(But if you're working with a large number of folks, it's always better to err on the side of being as cautious as possible, no?)
