16 or 17
years old in 2026
Everyone born in 2009 turns 17 on their birthday in 2026. By October 25, people with birthdays from January 1 to October 25 are already 17, and the rest are still 16. The Pew Research Center counts 2009 births in Generation Z, which runs from 1997 to 2012. Most of 2009 was the year of the Earth Ox in the Chinese zodiac. Lunar New Year came on January 26, 2009, so babies born before it are the Earth Rat.
