Rosalynn and former President Jimmy Carter are celebrating their 75th anniversary on Wednesday.

According to the Associated Press, their marriage is the longest presidential marriage in American history.

In an interview with the AP, the former president, 96, said the secret to a long marriage is picking the right partner, calling his marriage to Rosalynn, 93, “a full partnership.”

The couple married in the summer of 1946.

The couple said they read the Bible together daily, find things to do together, and before going to sleep every night, they work out any differences.

“Every day, there needs to be reconciliation and communication between the two spouses,” the 39th president said.

The Carter’s live in the same town they were born in, grew up in, and had their first date.

The couple plans to celebrate the milestone with a party in Plains a few days after their anniversary.
