Calculator
Enter your birth date and any year — 1900 to 2200 — to see your exact age on your birthday that year, whether it's decades behind or decades ahead.
Subtracting birth year from target year gets you within one year, but not the exact answer — it depends on whether your birthday in that target year falls before or after whatever reference point you're comparing against. This tool does the full calculation, showing your exact age on your birthday in that specific year, so there's no manual adjustment needed.
For your age as of today specifically, the standalone Age Calculator is simpler. For a general year — without needing an exact birth date — Age by Birth Year covers 1930 through 2026.
