I dont' even know what Eid mubarak is? It isn't English that's for sure
true not english
same here.
It's a greeting used on two Islamic holy days. https://en.wikipedia.org/wiki/Eid_Mubarak
"Eid mubarak" is just kind of a "Happy Eid", but it's Arabic and you wouldn't really use it in Indonesia. Most people would say "Selamat Idul Fitri/Adha"
