how old is aang in avatar

Aang in "Avatar: The Last Airbender" is physically 12 years old when he re- emerges from the iceberg at the start of the series, but he is technically 112 years old, accounting for the 100 years he spent frozen in the iceberg. By the end of the series, Aang is about 12 or just turning 13 years old in physical age, while chronologically he is still 112 to 113 years old due to the time in suspended animation.
