B’Day is the 2006 Beyoncé album named after the nickname associated with her birth date.
B’Day was released on September 4, 2006, Beyoncé’s 25th birthday. The title combines the letter B from her first name with “day,” creating a birthday reference while also echoing the compact naming style of a celebration. The album followed her debut Dangerously in Love and expanded her role as a writer and producer.
Its singles included “Déjà Vu,” featuring Jay-Z, “Ring the Alarm,” and “Irreplaceable.” “Irreplaceable” became one of Beyoncé’s biggest U.S. hits, spending ten weeks at number one on the Billboard Hot 100. The album’s sound draws on R&B, pop, funk, and soul.
B’Day is often confused with Beyoncé’s self-titled album because both titles begin with the letter B and both had strong visual components. However, B’Day is the 2006 birthday-timed release, while Beyoncé arrived in 2013 as a surprise visual album.
