What is Birthday Called ?

A birthday is the anniversary of the birth of a person. It is typically celebrated with a birthday party, gift-giving, and the presence of friends and family. Birthdays are often marked by a person's age, and milestones such as 16, 18, 21, 30, 40, 50 and so on are often considered significant. Birthdays are often celebrated with a cake, candles and the singing of "Happy Birthday to You" song. Some people also celebrate their birthday by doing something special or going on a trip.
