Birthdays are celebrated all over the world. Some ways to celebrate birthdays are rather similar from county to country---candles, cakes and birthday wishes. But there are also different ways to celebrate birthdays. Here are a few:

Denmark A flag is flown outside a window to show that someone who lives in the house is having a birthday. Presents are placed around the child’s bed while he is sleeping so he will see them at once when he wakes up.	India Usually Indian children wear white to school. However, on their birthdays, children wear colored clothes to school and give out chocolate to everyone in the class. Their best friends help them to do this.
Japan The birthday child wears new clothes to mark the special time. Certain birthdays are more important than others. These are the third and seventh for girls and fifth for boys.	Holland The birthday child receives an especially large present. The family also puts flowers on the birthday child’s chair to make it beautiful.
