Joe Biden is 83 years old in 2025, the oldest living U.S. president, having left office at 82 years and 61 days on January 20, 2025. His age at every milestone — Senate at 29, president at 78 — has drawn sustained attention as both a political talking point and a factual matter of record.

Born: November 20, 1942 · Current Age: 83 (as of November 2025) · President at Age: 78 · Spouse: Jill Biden, 74

When Was Joe Biden Born?

Joe Biden’s full birthdate is November 20, 1942 — making him a Scorpio born in Scranton, Pennsylvania, raised in modest circumstances that would shape much of his political identity. His birth year places him firmly in the baby boom generation, now in his eighties alongside a shrinking group of living former presidents.

Birth Date and Place

The records are straightforward: Joseph Robinette Biden Jr. entered the world on November 20, 1942, in Scranton. He was the first of four children in a Catholic family that later moved to Wilmington, Delaware. He would return to the Senate in 1972 at age 29 — making him one of the youngest senators in modern history — before his decades-long career eventually led to the White House.

How Old is Joe Biden When He Became President?

Biden took the oath of office on January 20, 2021, at the age of 78 years and 61 days — making him the oldest president to take office for the first time in U.S. history at that moment. The record he set would not last long, however.

Age at Inauguration

When Biden placed his hand on the Bible that frigid January morning, he had already spent nearly 50 years in public office. Statista notes that the average U.S. president takes office at around 57 years old, with a median of 55 — putting Biden roughly two decades beyond the typical debut age for a commander-in-chief. His inauguration age of 78 years and 61 days was verified across multiple sources including POTUS.com and remains one of the most cited facts about his presidency.

How Old Was Joe Biden When He Left Office?

Biden’s single term ended on January 20, 2025, when he departed Washington at 82 years and 61 days old — matching the age at which Donald Trump’s second term will also conclude in 2029, according to Statista’s historical projections.

Age at Term End

His birthday on November 20, 2024, marked his 82nd year. CBS News confirmed that he turned 82 on that date, making him 82 years and roughly two months when he left the White House. He remains the oldest living U.S. president by a comfortable margin. As of late 2025, he is 83 years old — an age that places him in a category of presidential longevity that few have matched.

How Old is Joe Biden’s Wife?

Jill Biden, the former second lady and first lady, was born June 3, 1951, making her approximately 74 years old as of November 2025. She is seven years Joe Biden’s junior — a gap that places her among the older spouses of a U.S. president, though not an unusual one historically.

Jill Biden’s Age

Dr. Jill Biden has maintained an active public profile throughout her husband’s presidency, teaching remotely and participating in policy initiatives around community college access and military family support. Her 1951 birth year means she was 69 when her husband was inaugurated — and she left the White House at 73, an age at which many Americans are still in the workforce, as she herself has been.

How Old Are Joe Biden and Donald Trump?

This is where the age story gets genuinely interesting: both men have now been 78 at their inaugurations, but Trump edged past Biden by a matter of months to claim the overall record. Biden was 78 years and 61 days at his 2021 inauguration; Trump was 78 years and 220 days when he took office again on January 20, 2025.

Age Comparison Table

Three presidents span nearly two decades of age difference among the current living group. Biden and Trump are both in their eighties, Obama is in his sixties, and Reagan — who left office in 1989 — spent his final years in his eighties as well.

Trump is roughly four years older than Biden despite being inaugurated at the same nominal age — the five-month gap at the time of their respective oath-taking reflects when their birthdays fall relative to January 20. CBS News confirms Trump turned 79 on June 14, 2025, while Biden had already turned 82 the previous November.

Obama Comparison

Obama offers a striking counterpoint: he was inaugurated at 47 years and 169 days in 2009, making him the fifth youngest president ever at that milestone. By comparison, Biden was 31 years older on his inauguration day. Obama left office at 55 years and 169 days — roughly 27 years younger than Biden when Biden departed. The gap illustrates how the age distribution among recent presidents has skewed sharply older since Reagan’s era.

Donald Trump’s victory in 2024 made him the oldest man ever elected as president, where he will be 78 years and seven months old when taking office again.
