Birthday

A birthday is an occasion when a person or institution celebrates the anniversary of their birth. Birthdays are celebrated in numerous cultures, often with a gift, party, or rite of passage.

Many religions celebrate the birth of their founders with special holidays (e.g. Christmas, Buddha's Birthday).

Note the distinction between birthday and birthdate: The former, other than February 29, occurs each year (e.g. May 11), while the latter is the exact date a person was born (e.g., May 11, 1998).

Legal conventions

In most legal systems, one becomes designated as an adult on a particular birthday (usually between 12 and 21), and reaching age-specific milestones confers particular rights and responsibilities. At certain ages, one may become eligible to leave full-time education, or become subject to military conscription or to enlist in the military, to consent to sexual intercourse, to marry, to marry without parental consent, to vote, to run for elected office, to legally purchase (or consume) alcohol and tobacco products, to purchase lottery tickets, or to obtain a driver's licence. The age of majority is the age when minors cease to legally be considered children and assume control over their persons, actions, and decisions, thereby terminating the legal control and legal responsibilities of their parents or guardian over and for them. Most countries set majority between 18 to 21.

Katy Perry

Katheryn Elizabeth "Katy" Hudson (born October 25, 1984), known professionally as Katy Perry, is an American singer, songwriter, and actress. After singing in church during her childhood, she pursued a career in gospel music as a teenager. Perry signed with Red Hill Records and released her debut studio album Katy Hudson in 2001, which was commercially unsuccessful. She moved to Los Angeles the following year to venture into secular music after Red Hill ceased operations. After being dropped by The Island Def Jam Music Group and Columbia Records, Perry signed a recording contract with Capitol Records in April 2007.

Perry rose to fame in 2008 with the release of the singles "I Kissed a Girl" – which sparked controversy for its homosexual themes – and "Hot n Cold" from her second album, a pop rock record titled One of the Boys. Her third album, Teenage Dream (2010), ventured into disco, and contained the U.S. Billboard Hot 100 chart-topping singles "California Gurls", "Teenage Dream", "Firework", "E.T.", and "Last Friday Night (T.G.I.F.)" as well as the number-three single "The One That Got Away". The album became the first by a female artist to produce five number-one Billboard Hot 100 songs, and the second overall after Michael Jackson's album Bad. In March 2012, she reissued the album as Teenage Dream: The Complete Confection, which produced the songs "Part of Me" and "Wide Awake".

2 Chainz

Tauheed Epps (born September 12, 1977), better known by his stage name 2 Chainz (formerly Tity Boi), is an American rapper from College Park, Georgia. He initially gained recognition for being one-half of the Southern hip hop duo Playaz Circle, alongside his longtime friend and fellow rapper, Earl "Dolla Boy" Conyers. They are perhaps best known for being signed to fellow Georgia-based rapper Ludacris' Disturbing tha Peace label, as well as their debut single "Duffle Bag Boy".

In February 2012, Epps signed a solo record deal with Def Jam Records, an imprint of Universal Music Group. The following August, he released his debut studio album Based on a T.R.U. Story, to mixed reviews. The album spawned three successful singles: "No Lie", "Birthday Song", and "I'm Different", all of which charted in the top 50 of the Billboard Hot 100 and were certified Gold or higher by the RIAA, along with the album being certified Gold. His second studio album B.O.A.T.S. II: Me Time was released on September 11, 2013. It was supported by the singles "Feds Watching", "Where U Been?", and "Used 2".

Kanye West

Kanye Omari West (/ˈkɑːnjeɪ/; born June 8, 1977) is an American recording artist, record producer, fashion designer and entrepreneur. He is the founder of the record label GOOD Music and creative content company DONDA. West is one of the most acclaimed musicians of the 21st century. He has attracted both praise and criticism for his work and his controversial, outspoken public persona.

Raised in Chicago, West first became known as a producer for Roc-A-Fella Records in the early 2000s, producing hit singles for musical artists such as Jay-Z and Alicia Keys, before pursing a solo career as a rapper. In 2004, he released his debut album The College Dropout, to widespread commercial and critical success, and founded record label and management company GOOD Music. He went on to explore a variety of different musical styles on subsequent albums that included the baroque-inspired Late Registration (2005), the electronic-tinged Graduation (2007), and the starkly polarizing 808s & Heartbreak (2008). In 2010, he released his critically acclaimed fifth album My Beautiful Dark Twisted Fantasy. He collaborated with Jay-Z on Watch the Throne (2011), and released his sixth album, Yeezus, to further critical praise in 2013. Following a series of recording delays and work on non-musical projects, West's seventh album, The Life of Pablo, was released in 2016.
