Birth date verification and age calculation method
Verified birth details
Authoritative public records, including legal documents and widely cited biographies, list Bill Gates’s date of birth as October 28, 1955. This fixed point allows precise computation of his age in 2025 or any other year. Age is calculated as the difference between the target date and birth date, adjusted for whether the birthday has occurred in the target year.
How to determine his exact age in 2025
- Before October 28, 2025: subtract 1955 from the year and adjust for whether the birthday has occurred (age = 2025 − 1955 − 1 = 69 if birthday not yet passed).
- On and after October 28, 2025: his age becomes 2025 − 1955 = 70 on his birthday and remains 70 through the end of the year.
Time-zone and calendar corrections are generally unnecessary for age in years, and any reputable source will align to the Gregorian calendar date above.
