The story has no real-world years, so only his age in the story is used. The manga states his age at the three World Martial Arts Tournaments he enters as a youth (12, 15 and 18); later ages follow the elapsed time the story states (five years to Raditz, seven years dead, ten years to the final tournament) and the official Dragon Ball timeline (born Age 737).
