I will give my 2 cents: in the 90s, my Italian family held a vigil of sorts at home, with a rosary prayer and then dinner with some dishes that were only prepared in this occasion (nothing overly fancy, over time it just got associated). Nowadays, I think some nuclear families still hold a short vigil, but mine doesn’t anymore. It feels it got less popular with the drop of religious attendance/affiliation.

Trick or treating is becoming increasingly common, (as in: it used to not exist and now some kids go around, not many).

I honestly forgot about it this year, until yesterday evening. Next year I’ll try to carve a pumpkin and do my grandma’s special recipe.
