21 or 22
years old in 2026
Everyone born in 2004 turns 22 on their birthday in 2026. By October 25, people with birthdays from January 1 to October 25 are already 22, and the rest are still 21. The Pew Research Center counts 2004 births in Generation Z, which runs from 1997 to 2012. Most of 2004 was the year of the Wood Monkey in the Chinese zodiac. Lunar New Year came on January 22, 2004, so babies born before it are the Water Goat.
