How Old Am I If I Was Born in 2003?

22 or 23
years old in 2026
Everyone born in 2003 turns 23 on their birthday in 2026. By October 24, people with birthdays from January 1 to October 24 are already 23, and the rest are still 22. The Pew Research Center counts 2003 births in Generation Z, which runs from 1997 to 2012. Most of 2003 was the year of the Water Goat in the Chinese zodiac. Lunar New Year came on February 1, 2003, so babies born before it are the Water Horse.
