Periodic reminder:

If you're in charge of dates for a professional event, check the Jewish liturgical calendar before locking in your dates

Jewish friends please correct me if I need it but this is my basic understanding:

The "top tier" holidays are Passover, Rosh Hashanah, and Yom Kippur. If you schedule professional events over them you're imposing hardship on your Jewish colleagues.

Yom Kippur is especially important and especially tricky, because many people observe it by fasting -- total fasting, no water. So anything just after Yom Kippur is going to be hard, too.

Passover, on the other hand, can demand a lot of preparation right beforehand. Many people do a ton of cleaning, and it can be a big family meal holiday as well. (With all the stress and family feelings that can bring.)

I would also keep a particular eye out of Tisha B'Av and Yom HaShoah. Tisha B'Av is another major fasting day, and I don't know in detail how Yom HaShoah is observed but it's likely to be a tough day for people.

Let's attach this to the main thread actually https://twitter.com/yechielk/status/1308099657109778434

This is, honestly, a good example of one of my big blindspots around Judaism.

My religious education is relatively good but growing up I was taught about... Passover and... Chanukah.

There are a *lot* more than that, and a lot more big ones than that.

And, like, none of this even touches on Shabbat, which is weekly and requires prep, especially in the winter when it starts quite early.

Fun fact, I learned about Purim ~2 years ago, when I discovered Jewish Twitter and then in February/March everyone suddenly started arguing about pastry. https://twitter.com/yechielk/status/1308105273018658817
