How old am I if I was born in 2004?
21 or 22
You are 22 if your birthday has already happened in 2026, and 21 if it is still ahead. A year on its own cannot narrow it further — both answers are right for part of the year, which is why a single number would be wrong for most of it.

Age in each year
The same two-part answer, for the years either side of this one. Anyone born in 2004 is the first number until their birthday and the second afterwards.

Working it out exactly
2004 was a leap year, so anyone born on 29 February that year has a birthday only once every four years — 6 leap days have passed since, and the next 29 February is the one that counts.
For an exact age in years, months and days from a full birth date, use the age calculator. It takes a date rather than a year, so it gives one answer instead of two.
