How old am I if I was born in 1984?

41 or 42

You are 42 if your birthday has already happened in 2026, and 41 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 1984 is the first number until their birthday and the second afterwards.

Milestone birthdays

Working it out exactly

1984 was a leap year, so anyone born on 29 February that year has a birthday only once every four years — 11 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.
