There's tons of different cultural festivals around places every month and I wonder if it's common for people not from those backgorunds to celebrate/partake in it. For example Chinese New Year, Dia de Muertos, Independence days etc.
In Europe some countries are multicultural like the US but we don't have the same large scals influence as walking to a China town. I was surprised to hear a friend from UK try thanksgiving this year due to how influental it was in his tiktok feed last year.
