Everyone born in 1966 turns 60 on their birthday in 2026. By October 26, people with birthdays from January 1 to October 26 are already 60, and the rest are still 59. The Pew Research Center counts 1966 births in Generation X, which runs from 1965 to 1980. Most of 1966 was the year of the Fire Horse in the Chinese zodiac.
