The 100 seats in the United States Senate are divided into 3 classes to determine which seats will be up for election in any 2-year cycle, with only 1 class being up for election at a time. With senators being elected to fixed terms of 6 years, the classes allow about a third of the seats to be up for election in any presidential or midterm election year instead of having all 100 be up for election at the same time every six years. The seats are also divided in a way that any given state's 2 senators are in different classes so that each seat's term ends in different years. Class 1 and class 2 consist of 33 seats each, while class 3 consists of 34 seats. Elections for class 1 seats are scheduled to take place in 2024, class 2 in 2026, and the elections for class 3 seats in 2028.
