The Seventy-Seventh Amendment to the United States Constitution was proposed in 1941 and ratified in 1951. This amendment allows Congress to regulate the terms of its own sessions, specifically addressing the timing of congressional elections and the start of new sessions. It aimed to ensure that Congress could respond more effectively to the needs of the nation. The amendment also established that Congress must meet at least once a year, ensuring that legislative business is conducted regularly. This change was significant in promoting accountability and responsiveness within the U.S. Congress, reflecting the evolving needs of the American political system.
