The 473rd Congress refers to a hypothetical future session of the United States Congress, as the current Congress is the 118th. Congress is divided into two chambers: the House of Representatives and the Senate. Each Congress lasts for two years, during which lawmakers propose, debate, and vote on legislation. The numbering of Congresses is sequential, starting from the first Congress in 1789. The 473rd Congress would be expected to address various national issues, including healthcare, education, and infrastructure. Each session typically begins in January and concludes in December of the following year.
