The two possible birth years for a 25-year-old
Birthday already passed this year
2001
Born 2026 − 25 = 2001. Your birthday fell between January 1 and today, so you have already turned 25 in 2026.
Birthday still coming this year
2000
Born 2026 − 25 − 1 = 2000. Your birthday is later in 2026, so you are still 24 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 − 25 = 2001. Then apply one simple correction — if your birthday hasn't happened yet this year, subtract one more year (2000). That's why "what year would i be born in if i was 25" always has two valid answers until your birthday arrives.
