"Happy Birthday to You", also known as "Happy Birthday", is a song traditionally sung to celebrate the anniversary of a person's birth. According to the 1998 Guinness World Records, it is the most recognized song in the English language, followed by "For He's a Jolly Good Fellow". The song's base lyrics have been translated into at least 18 languages. The melody of "Happy Birthday to You" comes from the song "Good Morning to All", which has traditionally been attributed to American sisters Patty and Mildred J. Hill in 1893, although the claim that the sisters composed the tune is disputed. A birthday is the anniversary of the birth of a person, or figuratively of an institution. Birthdays of people are celebrated in numerous cultures, often with birthday gifts, birthday cards, a birthday party, or a rite of passage.
