Donald Trump turns 71 today. Here’s how his age stacks up against other world leaders.

Donald Trump turns 71 today, becoming only the second US president to hit that age while in office. Serving two terms would see him overtake former US president Ronald Reagan, who was two weeks shy of 78 when he left office.

Trump is the fourth-oldest leader in the G20, and oldest elected leader after South Africa’s Jacob Zuma, who is 75. (Saudi Arabia and Brazil have leaders old than Trump, but the former is a monarchy and the latter installed its vice president in the top office after president Dilma Rousseff was impeached.)

We hope Trump enjoys all his favorite things on his 71st.
