What is Rocky Balboa's listed birth date in franchise character biographies?

Rocky Balboa's listed birth date in franchise character biographies is July 6, 1945.

That date appears in the character biography for Robert “Rocky” Balboa, the Philadelphia boxer created and played by Sylvester Stallone. Rocky is introduced in the 1976 film as a working-class club fighter nicknamed “the Italian Stallion,” and later stories follow his rise to the heavyweight championship, retirement, and return to boxing-related life.

The date is a character-profile detail rather than a major plot point. The films do not generally build their stories around Rocky’s exact birthday, so viewers may encounter approximate ages or timeline-based calculations instead. Those calculations can become confusing because the series spans several decades and includes sequels, flashbacks, and later Creed-era appearances.

The answer is therefore the date listed in the franchise biography, not a date inferred from Rocky’s age in a particular movie. July 6, 1945 is the single direct answer used by the cited character reference.
