Everyone born in 1984 turns 42 on their birthday in 2026. By October 21, people with birthdays from January 1 to October 21 are already 42, and the rest are still 41. The Pew Research Center counts 1984 births in the Millennial generation, which runs from 1981 to 1996. Most of 1984 was the year of the Wood Rat in the Chinese zodiac.
