Beyoncé’s 2006 studio album named for her birthday is B’Day.
Columbia Records released B’Day on September 4, 2006, Beyoncé’s 25th birthday. The title combines the abbreviation “B” for Beyoncé with “Day,” creating a reference to both her name and birthday.
The album followed Dangerously in Love and included the singles “Déjà Vu,” “Ring the Alarm,” and “Irreplaceable.” “Irreplaceable” became one of Beyoncé’s best-known songs and spent ten weeks at number one on the Billboard Hot 100.
B’Day was recorded in a short, intensive period after Beyoncé completed work on Dreamgirls. Its sound blends contemporary R&B, pop, hip-hop, and funk. The title is often confused with the album 4, whose name refers to Beyoncé’s personal connection with the number rather than her birthday.
