The 50th birthday is often called a golden birthday, which is considered a festive jubilee. It is called a golden birthday because it is the day when someone turns the age of their actual birth date, such as turning 22 on the 22nd. The term "golden" is also used because it is a milestone birthday, marking the half point of a century. In addition to being called a golden birthday, it can also be referred to as a "Champagne birthday". The term "jubilee" can also be used to describe a 50th birthday, which is a special anniversary, especially a 25th or 50th one.
