Age by birth year
Here are four questions about being born in 2004, answered.
How old am I if I was born in 2004?
In 2026 you are 22 if your birthday has already passed this year and 21 if it has not. Today is Tuesday, November 3, 2026, counted in US Eastern time, so a birthday on or before November 3 has passed (you are 22) and one from November 4 on is still to come (you are 21).
How old will I be on December 31, 2026 if I was born in 2004?
You will be 22. Every birthday of 2026 has happened by December 31, so everyone born in 2004 is 22 on the last day of 2026, and 23 on December 31, 2027.
What year was I born if I am 22 in 2026?
You were born in 2004 if your birthday has already passed this year, or in 2003 if it has not come round yet. 2026 minus 2004 is 22, and someone born in 2003 is still 22 until their birthday this year.
In what year does someone born in 2004 turn 18?
2022, on the birthday in that year. Someone born in 2004 turns 21 in 2025 and 30 in 2034.
