An aide told The Associated Press that Carter will spend the day quietly at his home in southwest Georgia. No public appearances have been planned.
Online, The Carter Center collected birthday wishes for the former president and dozens of people shared well-wishes. Many did not mention Carter’s Democratic presidency, which ran from 1977 to 1981. Instead, most focused on his post-presidential life, when Carter began teaching Sunday school and -- through The Carter Center -- worked on addressing issues related to human rights and democracy.
“You are a true hero, speaking truth to power, and standing up for human rights everywhere,” one birthday greeting read . “You and your dear wife Rosalyn are the conscience of the nation, demonstrating wholeheartedly serving humanity through your examples.”
Jimmy and Rosalynn Carter founded The Carter Center in 1982. The couple celebrated 75 years of marriage in July.
