Most of my Eids have been spent at work. This time it fell on Black Friday, so everyone was off anyway, so I had off.
But usually, maybe Eid namaaz if I have a day off.
The rest of your questions are broad. I was born in America. I’m fairly American in my pastimes.
We don’t really do anything “cultural” anymore. Even down to the food I eat is mostly American. I used to go to Islamic school when I was a kid. I used to go to desi melas for Eid. I guess they still do them now - I never hear about them.
