I don't get it. Keep in mind that a lot of people here aren't muslim. 
Captain? 
In Islam, we have 2 Eids. The first one is after Ramadan and its normal, the second one happens in 10th of Tho Heja (Its an Arabic month, it doesn't have an exact date because it comes after 10 days than it did before in each year). In the second Eid (Tho Heja), we have to give away a sacrifice to poor people. And the sacrifice is (In most of times) a sheep, you can sacrifice a cow or a camel..etc (Anything but the forbidden Animals which we cant eat, like pigs.. for obvious reasons of course.. it eats shit and its blood is full of it lol).
Sorry my English isn't that great but I tried my best.
