The Jimmy Carter Library & Museum is moving up festivities for the former president’s 99th birthday because of the threat of a partial federal government shutdown.

Events originally scheduled for Sunday, Carter’s birthday, will now be held Saturday on the Atlanta campus of the library and the adjacent Carter Center. An end-of-Saturday deadline looms for Congress to reach a new budget agreement to keep all government offices — including presidential libraries and museums — open.

The commemoration is scheduled from from noon to 4 p.m. Satureday. It will include a 99-cent entry fee for the Carter museum, which features a replica of the Oval Office as it appeared during Carter’s 1977-81 White House term. Anyone 16 or younger will receive free admission. There will be birthday cake, games, crafts and food trucks on the grounds.
