What is Roger Federer's date of birth?

Roger Federer was born on 8 August 1981.

Federer was born in Basel, Switzerland, and became one of the defining tennis players of the modern era. He turned professional in 1998 and later spent 310 weeks ranked world No. 1, including a record 237 consecutive weeks at the time. His precise birth date is separate from the dates of his major career milestones.

He won 20 men’s singles Grand Slam titles, including a record eight Wimbledon singles championships. Federer also won the 2008 Olympic men’s doubles gold medal with Stan Wawrinka and helped Switzerland win the Davis Cup in 2014. He retired from professional tennis in September 2022.

A common source of confusion is the use of different date formats: “8 August 1981” is the same date as “August 8, 1981.” The other listed dates belong to no canonical Federer biography and should not be treated as alternate answers.
