Unlucky Numbers

Every counties have a number contain to bad luck, and every culture has a different number. In the U.S number 13 is contain to bad luck, and some poeple call today "Black Friday " because today is 13. I don't konw why this country 13 is the unlucky number, becuase I didn't born in here. But I do knew why number 4 contain to the unlucky number in China, because in Chinese number 4 is almost the same pronunciation with die. And that is why Chinese people didn't like 4.
