Easter? What's that?

I have often gone into a class with Spanish people and started talking about Easter, only to notice about 5 minutes later that nobody knows what I am talking about. They all say: "Easter? What is that?" Well, for those of you who don't know, "Easter" is "Semana Santa".

It is quite common for Spanish people to talk about this specific holiday as "the holy week" but in the UK we generally say "Easter" or "Easter Holiday" or even "Easter Sunday" for the specific day. Generally, it is traditional in the UK that children are given "Easter eggs" or that they need to search for them in the garden.  

So tell me: What are you doing for your "Easter" holidays?
