The two possible birth years for a 4-year-old
Birthday already passed this year
2022
Born 2026 − 4 = 2022. Your birthday fell between January 1 and today, so you have already turned 4 in 2026.
Birthday still coming this year
2021
Born 2026 − 4 − 1 = 2021. Your birthday is later in 2026, so you are still 3 until then.
How to work it out yourself
The formula for finding your birth year from your age is: birth year ≈ current year − your age. For you: 2026 − 4 = 2022. Then apply one simple correction — if your birthday hasn't happened yet this year, subtract one more year (2021). That's why "what year would i be born in if i was 4" always has two valid answers until your birthday arrives.

Common questions about being 4 years old
If I am 4, what year was I born in?
If you are 4 years old right now, you were born in either 2021 or 2022. You were born in 2022 if your birthday has already happened in 2026, and in 2021 if it is still coming. Enter your full date of birth in the calculator above for the exact date.
What year would I be born in if I was 4 years old?
Subtract your age from the current year: 2026 − 4 = 2022. If your birthday has not occurred yet this year, subtract one more — 2022 − 1 = 2021. So the answer is 2021 or 2022 depending on whether your birthday has passed.
How do I know if I was born in 2022 or 2021?
Check your birthday month/day vs today. If today is on or after your birthday in 2026, you were born in 2022; if before, you were born in 2021. The calculator above works it out exactly, including months/days.
What generation is a 4-year-old?
It depends on which year you were born: 2022 is Generation Alpha and 2021 is Generation Alpha. See both on the birth-year guide for 2022.
What Chinese zodiac is someone who is 4?
Either Year of the Ox (if born in 2021) or Year of the Tiger (if born in 2022). Zodiac cycles every 12 years — e.g. 2010 is also Tiger.
When will I turn 5?
If you are 4 now, you turn 5 sometime in 2026 on your next birthday. Use Compare Ages to see how your age lines up with family/friends on any past or future date.
