How old am I if I was born in 2017?
8 or 9
You are 9 if your birthday has already happened in 2026, and 8 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 2017 is the first number until their birthday and the second afterwards.

Working it out exactly
2017 was not a leap year. Someone born in 2017 has lived through 2 leap days, which is why counting an age in days needs a calendar rather than a multiplication.
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.
