Here are the years in which someone born in 2005 reaches each milestone age.
A birthday in 2005 plus the age gives the year, and the birthday itself decides whether it is the earlier or the later of two years where the table shows both.

Here are four questions about being born in 2005, answered.
- How old am I if I was born in 2005?
- In 2026 you are 21 if your birthday has already passed this year and 20 if it has not. Today is Monday, October 26, 2026, counted in US Eastern time, so a birthday on or before October 26 has passed (you are 21) and one from October 27 on is still to come (you are 20).
- How old will I be on December 31, 2026 if I was born in 2005?
- You will be 21. Every birthday of 2026 has happened by December 31, so everyone born in 2005 is 21 on the last day of 2026, and 22 on December 31, 2027.
- What year was I born if I am 21 in 2026?
- You were born in 2005 if your birthday has already passed this year, or in 2004 if it has not come round yet. 2026 minus 2005 is 21, and someone born in 2004 is still 21 until their birthday this year.
- In what year does someone born in 2005 turn 18?
- 2023, on the birthday in that year. Someone born in 2005 turns 21 in 2026 and 30 in 2035.
Turnover is cheaper to prevent than to calculate.
