What is Peter Parker’s birthday?

Peter Parker, also known as Spider-Man, is a fictional superhero created by Stan Lee and Steve Ditko for Marvel Comics. Determining Peter Parker’s exact birthday requires looking at the original comics that introduced the character.

When Spider-Man First Appeared

Spider-Man made his first appearance in Amazing Fantasy #15 in August 1962. This issue provided some background on Peter Parker and how he gained his spider powers, but did not explicitly state his age or birthday.

Early References to Peter Parker’s Age

In early Spider-Man comics in the 1960s, Peter Parker is depicted as a high school student. Specifically, he is shown as a sophomore in high school in Amazing Spider-Man #1 in March 1963 and later a senior in Amazing Spider-Man #28 in September 1965.

Based on typical high school grade levels, this would suggest Peter Parker was likely 15 or 16 years old when he became Spider-Man in 1962. This aligns with a reference Peter makes to being 15 years old in Amazing Fantasy #15 when he is bitten by the radioactive spider.

Peter Parker’s High School Classmates

Further clues about Peter Parker’s age can be found by looking at his classmates in high school. Key classmates include:

  • Flash Thompson – Depicted as the same age/grade as Peter Parker in high school.
  • Liz Allan – Flash Thompson’s girlfriend, also the same age range as Peter.
  • Harry Osborn – Norman Osborn’s son who befriends Peter, similar age as well.

Birthday References in later Comics

In the comics after Peter graduates high school, there are occasional direct references to his birthday:

  • Amazing Spider-Man #17 (1964) – States Peter’s birthday is approaching as he prepares to graduate high school.
  • Amazing Spider-Man #18 (1964) – Peter celebrates his birthday shortly after graduating high school.
  • Amazing Spider-Man #252 (1984) – Gives Peter’s birthday as August 10th.


Based on these references, Peter Parker’s birthday appears to be on August 10th, and he was likely 15 or 16 years old in 1962 when he first became Spider-Man. This would place Peter Parker’s year of birth around 1946-1947.

While not definitively stated early on, clues from his high school peers and later direct comic references establish Peter Parker’s birthday as August 10th, making him a Leo!

Here is a quick timeline summarizing key dates related to Peter Parker’s birthday:

Additional References to Peter Parker’s Age

There are some additional comics that provide insight into Peter Parker’s age over the years:

  • Amazing Spider-Man #21 (1965) – Aunt May references Peter being 18 years old.
  • Amazing Spider-Man #98 (1971) – Peter celebrates his 23rd birthday.
  • Spectacular Spider-Man (2003) – Peter’s tombstone lists his birth year as 1947.

While there some inconsistencies in the comics as to time passage, most accounts point to Peter Parker being born in 1946 or 1947, making August 10th his established birthday in the Marvel universe.

Peter Parker’s Birthday in Other Media

While August 10th appears to be Peter Parker’s officially recognized birthday in the comics, there are some variations on this date in other Spider-Man media over the years:

  • In the 1967 Spider-Man animated series, his birthday is given as June 9th.
  • In the Ultimate Spider-Man comics, his birthday is listed as August 15th.
  • In the Marvel Cinematic Universe, his birthday has not been definitively established in the films or tie-in media.

So while not always consistent, the most commonly used date seems to be August 10th as first established in the main Marvel comics universe in 1984. This lines up well with the references to Peter’s age as a high school student in the early 1960s comics.


Based on an analysis of references in the original Spider-Man comics, Peter Parker’s generally accepted birthday is August 10th. This date fits with the timeline of Peter in high school in the early 1960s and hints about his age prior to Spider-Man’s first appearance in 1962.

While some other media uses different dates, the comics established August 10th as Peter Parker’s canonical birthday. So when wishing your friendly neighborhood Spider-Man a happy birthday, be sure to mark your calendars for August 10th!
