To determine the canonical birth years of some of these characters, I used the book Marvel Studios’ The Marvel Cinematic Universe: An Official Timeline as a reference. This book provides a chronological overview of the events and characters in the MCU.
Kamala Khan / Ms. Marvel: 2008 or 2009
One of the youngest heroes in the MCU is Kamala Khan, also known as Ms. Marvel. She makes her debut in the TV series Ms. Marvel, which takes place in Fall 2025, according to the official timeline. In the first episode, she reveals that she is 16 years old, so we can infer that she was born either in 2008 or 2009. She also appeared in the movie The Marvels, which is set right after the post-credits scene of the final episode of Ms. Marvel Season 1, as confirmed by director Nia DaCosta, which means she's still 16 years old at the time of the film's events.
Marc Spector / Moon Knight: March 9, 1987
In Moon Knight (TV series), we get a glimpse of Marc Spector’s US passport, which shows his date of birth as March 9, 1987. This means that Marc was 38 years old at the time of the series, which is set in Spring 2025 as per the official timeline.
Kate Bishop / Hawkeye: 2002
The official timeline places Hawkeye (TV series) in December 2024, where we learn that Kate Bishop is 22 years old. Later, in the mid-credits scene of The Marvels, which follows right after Ms. Marvel (set in Fall 2025), Kate Bishop mentions that she is 23 years old. From this information, we can deduce that her birth year is 2002.
Monica Rambeau: 1983 or 1984
Monica Rambeau appears as a child in Captain Marvel, which takes place in the summer of 1995, according to the official timeline. The actress who portrayed her in the film, Akira Akbar, was credited as “Monica Rambeau (11 Years Old)," implying that Monica was born in either 1983 or 1984. This is further supported by the fact that Azari Akbar, who played Monica in flashbacks (set in the late 1980s), was credited as “Monica Rambeau (5 Years Old)”. This puts Monica’s birth year in either 1983 or 1984.
Aaron Davis / Prowler: April 15, 1984
Aaron Davis’ date of birth was revealed by Karen, the AI in Spider-Man’s suit, in Spider-Man: Homecoming. She used facial recognition to scan his face and searched law enforcement databases to find his records.
Peter Parker / Spider-Man: August 10, 2001
In Spider-Man: Homecoming, which is set in the fall of 2016 according to the official timeline, Peter tells Tony Stark that he is 15 years old. This means he was born in either 2000 or 2001, depending on when his birthday falls. Luckily, we have a clue about that as well. In the teaser trailer for Spider-Man: Far From Home, we get a glimpse of Peter’s passport, which shows his date of birth as August 10. Putting these pieces together, we can conclude that Peter was born on August 10, 2001.
Peter Quill / Star-Lord: 1980
The official timeline confirms that Peter Quill was born in 1980. This is also evident from a flashback scene in Guardians of the Galaxy Vol. 2, where we witness Meredith Quill and Ego enjoying a romantic day in 1980, suggesting that Peter was conceived shortly after.
According to the official timeline, the events of the first Guardians of the Galaxy film took place in the summer of 2014, followed by the second one in the fall of the same year. This puts Peter at 33 or 34 years old during the events of these two films.
1980 | Ego Expands to Earth
After thousands of years of planting the seeds of his universal Expansion, the Celestial known as Ego sends his avatar to Earth (specifically, Missouri) and falls in love with the human Meredith Quill. She gives birth to a son, Peter, and raises him mostly as a single mother. Ego finds himself inextricably drawn back to Meredith, but he implants a tumor in her head that will eventually kill her—a murderous impulse derived from a wish to avoid entanglements that might distract from his grand plan.
James Gunn, the director of the Guardians of the Galaxy trilogy, also verified this in a tweet, where he answered a fan’s question about Peter’s birthday.
Q: @JamesGunn When is Peter's birthday? Because if he was conceived in 1980, how was he born in 1980?
James Gunn: I can’t believe how many people have asked me this. Guys, a pregnancy IS ONLY 9 MONTHS (& she could already be pregnant at the start of 2)."
Sam Wilson / Falcon / Captain America: September 23, 1978
A “Marvel Studios Secret Archives” video was uploaded by the official Marvel Latin America Facebook page, which revealed that Sam Wilson was born on September 23, 1978.
Loki: 965 — give or take a year
According to the official timeline, Loki was adopted by Odin as a baby around 965 CE. We can reasonably guess that he was born during that year — give or take a year. This means that Loki was about 1053 years old when he faced his tragic fate in Avengers: Infinity War, which happened in Spring 2018, according to the official timeline.
