A winner has been named in the 2020 U.S. election, but one of the major topics of discussion among both Republicans and Democrats during the campaign was Joe Biden's age.

The president-elect is currently 77 years old and will be turning 78 on November 20.

This means that he will officially become the oldest person to ever serve as the nation's commander-in-chief, with the previous record being set by his immediate predecessor, Donald Trump.

78 How old Joe Biden will be at his inauguration

Trump was inaugurated on January 20, 2017, at age 70, beating the previous age record set by Ronald Reagan, who was 69 at the time he was sworn in.

On the opposite end of the spectrum, the youngest person to assume the office is Theodore Roosevelt who served as vice-president before stepping into the role at age 42 following the assassination of William McKinley.

The youngest person ever elected to the office through an election was John F. Kennedy, who was inaugurated in 1961 at age 43.

Joe Biden was projected as the winner of the 2020 election on November 7.
