start of each term of congress
Congress convenes on January 5 of odd number years. The start of the next Congress is January 3, 2017.
U.S. Congresses are numbered based on the terms of the members of the U.S. House of Representatives, all of whom are elected every two years to two-year terms. Representatives and Senators who served from 4 March 1789 until 3 March 1791 were members of the 1st Congress, those who served from 4 March 1791 until 3 March 1793 made up the 2nd Congress, and so on. Note that since Senators are elected to six-year terms, that means that each Senator is elected to serve in three Congresses. For example, Class 1 Senators who were elected in 2012 were elected to serve in the 113th, 114th and 115th Congresses. The 1st through 72nd Congresses began on 4 March of the odd-numbered years from 1789 to 1931 and ended on 3 March two years later. The 73rd Congress began on 4 March 1933 and ended on 3 January 1935. The 74th through 112th Congresses began on 3 January of the odd-numbered years from 1935 to 2011 and ended on 3 January two years later. The 113th Congress began on 3 January 2013 and will end on 3 January 2015.

From 1789 to 1933, the terms of U.S. Senators and U.S. Representatives always started on March 4 of odd-numbered years. The 74th Congress (1935-1937) was the first to start on January 3, after the 1933 ratification of the 20th Amendment to the U.S. Constitution.
The dates of Congress' sessions have changed over the years, but since 1934, the first session convenes on Jan 3 of odd-numbered years and adjourns on Jan 3 of the following year, while the second session runs from Jan 3 to Jan 2 of even-numbered years.
