I just saw a discussion among corporate event planners where one person was upset that event organizers don’t give proper consideration to scheduling over top of Rosh Hashana and Yom Kippur.
I can appreciate the annoyance, when I was still a practicing Christian I would never think to schedule a work thing over Easter or Christmas. We should treat others with consideration, and should be mindful of what others view as important days. But I also don’t know what each religion considers to be major, non negotiable holidays. Do you?
Another question, does it matter where the event is? (for example, in the US should less consideration be given to holidays of religions that have fewer adherents?)
As a secular American, I can tell you my favorite holidays.
Independence Day - Hot Dogs, Outdoors, Beer, Fireworks
Thanksgiving - Food, Wine, Family
Halloween - Costumes, Candy, Booze
New Year’s Eve - Party, Champagne, usually a charcuterie board
St. Paddy’s Day - Beer, Corned Beef
Memorial Day/Labor Day - Backyard BBQs, Beer
Maybe my religion is alcohol.
