Jimmy Carter’s funeral will be held on January 9 in Washington

Mr. Carter, who died at his home in Plains, Ga., at 100 a.m. Sunday, will be flown by presidential plane Tuesday, Jan. 7, to Washington, where he will be taken to the U.S. Navy Memorial honoring his service as a submariner. He will then be taken by horse-drawn caisson up to the Capitol, where he will lie in state until January 8, as have several presidents dating back to Abraham Lincoln. Thousands of people are expected to file through the Rotunda to pay their respects, including lawmakers, diplomats and ordinary Americans.

The service at the cathedral, which traditionally hosts state funerals for presidents as well as other great American figures, will be the highlight of the memory. Other former presidents are expected to attend, but it was not clear whether President-elect Donald J. Trump, who has regularly disparaged Mr. Carter, would be invited or attend.

The military task force’s statement did not include a program for the cathedral ceremony, but others close to the planning said that in addition to Mr. Biden will have Jason Carter, the former president’s grandson and chairman of the board of the Carter Center, speak, as will Stuart E. Eizenstat, who was the former president’s domestic policy adviser.

Eulogies will also be read from two people who were close to Mr. Carter, but who are already dead: former President Gerald R. Ford, the Republican who was defeated by Mr. Carter in 1976, but went on to become a friend, and former vice president. President Walter F. Mondale, Mr. Carter’s deputy and partner. Mr. Ford died in 2006 and Mr. Mondale in 2021. The eulogy will be read by their sons, Steven Ford and Ted Mondale.

After the cathedral service, Mr. Carter be taken back to Georgia for burial. The original plans once called for him to be transported by train, but Mr. Carter objected. “If you take my cold, dead body across the United States by train, I will haunt you until the day you die,” he told an employee. So instead he returns to Georgia on a military flight.
