Trump is around 72 years old.
The president is 4 days younger than me. POTUS born June 14, 1946.
The President is 73 and will turn 74 on June 14 2020. On Jan 20 2025 he will be 78 and 7 months old. One could say he is atypical for his age since he seems to have a lot of energy and the Presidency has not worn him down as it has others.
