B’Day is the title of Beyoncé’s 2006 solo album named after her birthday month.
The album was released on September 4, 2006, Beyoncé’s 25th birthday. Its title is a stylized combination of “B” and “birthday,” linking the record directly to the singer’s birthday and initials.
B’Day followed her 2003 debut album, Dangerously in Love. It produced major singles including “Déjà Vu,” “Irreplaceable,” and “Beautiful Liar,” the last of which features Shakira. The album’s recording process was notably fast: much of it was made during an intensive period at Sony Music Studios in New York.
B’Day is sometimes confused with Beyoncé’s later self-titled album, released without advance promotion in 2013, or with the album 4, released in 2011. Its title is distinctive because it refers to a date-based celebration rather than a number or a character.
