As of 2025, Caitlyn Jenner is 74 years old. She was born William Bruce Jenner on October 28, 1949, in Mount Kisco, New York. To determine her current age, simply subtract the birth year from the present year and account whether her October 28 birthday has occurred yet in the current year. This profile clarifies her birth name, provides a reliable calculation method, and points to authoritative sources so you can confirm age information with high confidence.
How to calculate Caitlyn Jenner’s age
You can calculate Caitlyn Jenner’s age by subtracting 1949 from the current year and reducing by one if the date is before October 22 in the current year.
- Current year: 2025
- Birth year: 1949
- Birthday in 2025: October 28
- If today’s date is before October 28, 2025, subtract one from the simple year difference.
For example, on August 22, 2025, she is 74 (not yet having turned 75). On or after October 28, 2025, she turns 75. This method is accurate and works for any future year.
Birth name and identity context
Understanding her age is clearer when you also know her birth name and key life context. Caitlyn Jenner was assigned male at birth under the name William Bruce Jenner and came to broader public recognition as an Olympic gold medalist before her gender transition. Using both her birth name and current name helps avoid confusion in historical records and media coverage. Her public timeline includes the 1976 Olympics, reality television prominence, and ongoing public visibility, all of which are useful reference points when discussing her age in biographical context.

Common questions about her age

She is commonly referred to as the oldest among some of her better-known siblings in the broader Kardashian-Jenner extended family context. When comparing ages, always use the same reference date to avoid off-by-one errors, especially before and after her October 28 birthday.
Reliable sources to verify age
To reduce uncertainty, check authoritative references for birth date and age information. Official biographies, trusted news archives from major outlets, and reputable entertainment databases typically list October 28, 1949, as her birth date. Cross-referencing multiple reputable sources increases confidence. Be cautious with unverified social media posts or outdated articles that may not reflect the current year.
Why precise age matters in public discourse
Age can be relevant for health-related discussions, legal or financial contexts, and accurately framing career timelines. Misstating years can lead to confusion in timelines, such as Olympic achievements, television milestones, and personal life events. Using consistent, verifiable data ensures clarity whether you are discussing longevity in the public eye, generational comparisons, or biographical timelines.
