Princess Diana died at age 36 on 31 August 1997. She was born 1 July 1961 and passed away in the early hours of 31 August 1997 following a car crash in the Pont de l’Alma tunnel in Paris. This concise profile explains her age at death, outlines key biographical milestones, and cites verified sources to provide a clear factual timeline of her life.
Date of birth and date of death
Establishing how old Princess Diana was at death begins with two fixed dates: her birth on 1 July 1961 and her death on 31 August 1997. These dates are recorded in official registries and widely reported by reputable news and biographical sources, forming the baseline for any reliable age calculation. The interval between these dates spans 36 years, just under one full calendar year before her 37th birthday.
Birth registration
Her birth was formally registered in England, and primary biographical records list 1 July 1961 as her official date of birth. Contemporary hospital and civil registration documents corroborate this date and are referenced by authoritative biographies and institutional archives.
Death certificate and public timeline
The official death certificate issued in the United Kingdom and the French judicial report on the crash both confirm 31 August 1997 as her date of death. Public timelines produced by institutions including royal archives and major museums align with these dates and are updated only in light of formally corrected records.
Age calculation and calendar context
Calculating Princess Diana’s age at death involves straightforward date arithmetic: from 1 July 1961 to 31 August 1997 equals 36 completed years and just over one month. She would have turned 37 in just under two months at the time of her passing, which is consistently reported by timeline summaries and reference works.
- Age at death: 36 years
- Months lived beyond 36: ~1 month and 30 days
- Days until 37th birthday: 31
