Yes you should be entitled to a day off for it, but you are supposed to inform the school beforehand. They shouldn't be able to refuse it. Try to plan more in advance.
You mean in the UK right?
All children in Muslim countries like the UAE have a 5-7 day holiday over Eid.
Bruh jus stay home, what they gonna do arrest you¿ I’m pretty sure everybody who’s doing Eid is staying home, including myself
take the time off bestie !! one missed day isn't gonna impact your school work and you should enjoy eid !!
Christmas isn't the best comparison as it is largely a secular affair with Father Christmas, presents and pine trees. Those aren't really Christian things. Easter is a far better religious comparison as there are bank holidays for Good Friday and Easter Monday. These days don't hold any significance for non-Christians.
