Beyoncé’s 2006 album titled after her nickname and birth month is B’Day.
The title combines “B,” referring to Beyoncé, with “Day,” a reference to her birthday. The album was released on September 4, 2006, Beyoncé’s 25th birthday, giving the title an especially direct connection to the date.
B’Day produced several notable singles, including “Déjà Vu,” “Irreplaceable,” and “Beautiful Liar.” “Beautiful Liar” featured Shakira and became a major international hit. The album also supported Beyoncé’s expanding identity as a solo performer after Destiny’s Child’s period of group activity.
The title is commonly written as B’Day, with an apostrophe. It should not be confused with Beyoncé’s later albums 4, Lemonade, Renaissance, or Cowboy Carter. Its release-date wordplay is the key clue distinguishing it from those records.
