The two possible birth years for a 31-year-old
Birthday already passed this year
1995
Born 2026 − 31 = 1995. Your birthday fell between January 1 and today, so you have already turned 31 in 2026.
Birthday still coming this year
1994
Born 2026 − 31 − 1 = 1994. Your birthday is later in 2026, so you are still 30 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 − 31 = 1995. Then apply one simple correction — if your birthday hasn't happened yet this year, subtract one more year (1994). That's why "what year would i be born in if i was 31" always has two valid answers until your birthday arrives.
