Direct answer: Bill Clinton’s age at inauguration
Bill Clinton was 46 years old when he took office as the 42nd President of the United States. He was inaugurated on January 20, 1993, following the November 1992 election. The calculation is straightforward: he was born on August 19, 1946, and had already celebrated his 46th birthday about five months before the inauguration. This profile explains the exact dates, how the age is determined, and why the timing matters for presidential transitions and historical comparisons.
Bill Clinton’s birth date and early background
To determine a president’s age at inauguration, you start with their birth date and compare it to the inauguration date. For Bill Clinton, the key dates and biographic context are well documented by official records including White House archives and the National Archives.
- Full name: William Jefferson Clinton
- Date of birth: August 19, 1946
- Place of birth: Hope, Arkansas, United States
- Original surname at birth: William Jefferson Blythe III (changed after his mother married Roger Clinton in 1950)
These facts anchor all age calculations and are widely cited in reference works such as the Biographical Directory of the United States Congress and official presidential libraries. Establishing a precise birth date is essential for any reliable age determination at a specific point in time.
Inauguration date and age calculation method
The age of a president on inauguration is determined by subtracting the birth year from the inauguration year and adjusting for whether the birthday has occurred in that calendar year before the ceremony. The U.S. presidential inauguration is fixed by the 20th Amendment to the Constitution, which specifies noon on January 20 following the November election. For Bill Clinton:
- Birth date: August 19, 1946
- Inauguration date: January 20, 1993
- Elapsed time between dates: 46 years, 5 months, and 1 day
- Age on the day of inauguration: 46 years old
If the inauguration had occurred before August 19, he would have been 45 at the time. Because January 20 falls after his birthday each four-year cycle in non-leap-year transitions, he was always 46 or older during his inaugurations.
Historical context of Clinton’s presidency and age
Clinton’s age at inauguration places him among the younger modern presidents at the start of their first term. His birth in 1946 situates him between earlier postwar leaders and those who came into office after him. At 46, he was younger than George H.W. Bush (64 in 1989) and slightly younger than Ronald Reagan (69 in 1981) at their first inaugurations, but older than Barack Obama (47 in 2009) and significantly younger than Donald Trump (70 in 2017) and Joe Biden (78 in 2021) at their first inaugurations.
Context matters when comparing ages across eras, because life expectancy, career timelines, and political norms evolve. Clinton’s relatively young age at entry coincided with a focus on economic renewal and welfare reform, and it influenced perceptions of vigor and long-term political potential during his two terms.
Term dates and age at start of each term
Bill Clinton served two full terms, and his age at the start of each inauguration is easily verified. The table below summarizes the key dates and his age on each inauguration day.
| Term | Inauguration date | Bill Clinton’s age on that date |
|---|---|---|
| First term | January 20, 1993 | 46 years old |
| Second term | January 20, 1997 | 50 years old |
Both inaugurations occurred well after his birthday in August, confirming the ages shown. These milestones are consistent across authoritative sources such as the Miller Center, the Clinton Presidential Center, and the official federal records maintained by the National Archives.

How age at inauguration influences historical comparisons
When analysts compare presidencies, age at inauguration is one input among many, including prior experience, major events, and partisan context. Clinton was 46 when he first took office, which is younger than several of his predecessors and successors in the modern era. This can affect perceptions of leadership style, adaptability, and the length of political horizon during a presidency. However, age alone does not determine effectiveness; context, coalition-building, and global conditions also play decisive roles. Understanding the exact age and date helps reduce noise in such comparisons.
Common questions about presidential age at inauguration
Because age calculations appear frequently in historical and trivia discussions, a few recurring questions are worth clarifying up front.
- Why is the inauguration date always January 20?
- Does the time of day affect age at inauguration?
- How do you verify a president’s birth date?
- What if someone is confused about whether the birthday matters if it’s before or after the inauguration?
The 20th Amendment to the U.S. Constitution set this date, effective starting with the 1937 inauguration, moving it from March 4 to shorten the lame-duck period.
No. Age in years is typically computed using calendar dates; the precise hour is irrelevant for standard historical reporting.
Reliable sources include the National Archives, presidential libraries, and reputable biographical references that cite original documents such as birth certificates or hospital records where available.
You check whether the birthday has occurred in that calendar year before the inauguration. If it has, the person has already turned that age; if not, they are one year younger.
