Congress returns to Washington on Monday, November 9, six days after the midterm elections, and the weeks that follow will be among the strangest in the institution’s modern history. The lawmakers who come back are the outgoing Congress, elected in 2024, and they will keep all of their powers until noon on January 3, 2027, when their terms end and the new Congress convenes. The winners of the November 3 elections, who have been projected to give Democrats control of both chambers, will not take their seats until that day. Until then, the Republican majorities that voters have just rejected in projections still hold the gavels, still set the agenda, and still cast the votes that decide what becomes law. That gap between the election and the handover is called the lame-duck session, and this year’s version will decide how much of the outgoing majority’s unfinished business gets done before power changes hands.
The name comes from the fact that many of the lawmakers voting during these weeks are on their way out. Some lost their races. Some retired. Some are leaving for other reasons. They still hold their seats and can still vote, but they will not return in the next Congress. That gives the session an unusual character: decisions are made by people who will not have to live with the political consequences, and by leaders who are trying to protect their legacy, settle old scores, or clear the decks for their successors. It also gives the session a hard deadline. The current session must close by noon on January 3, and anything that has not passed by then generally has to be started again in the new Congress.
The calendar is tight. The House has 20 scheduled session days in the lame-duck period and the Senate has 22, according to figures cited in pre-election planning. Lawmakers are expected to be in session for about six or seven weeks, starting the week of November 9 and running until Christmas, with a break for Thanksgiving. When legislators return from their recess, they have eight scheduled working days between November 9 and November 20. The House would then return on November 30 and have 12 working days until adjourning on December 17. Twenty days is not much time for major legislation, and the competition for floor time will be intense.
What a lame-duck session is and why it matters
A lame-duck session is not a separate meeting with its own rulebook. It is a continuation of the session that has been running since the start of the year, extended past the election into the final weeks of the Congress. The members voting on what comes next are the ones serving now, and under the Twentieth Amendment their terms end at noon on January 3. Anyone elected on November 3 is not seated until that day. The distinction matters because it means the new Democratic majorities cannot yet do anything. They can plan, they can hold orientation sessions for new members, and they can negotiate with the outgoing leadership, but they cannot vote, cannot chair committees, and cannot issue subpoenas until the 120th Congress convenes.
The session also matters because of what is left undone. As of November 3, 2026, 829 bills and resolutions had passed one chamber but not the other, and all of them will die if they are not enacted before January 3. That backlog is normal at the end of a Congress, but it is larger than usual this year because the House and Senate spent much of the autumn in campaign recess, and because the two chambers were controlled by the same party yet still failed to move much of their agenda. The lame-duck session is the last chance to clear any of it, and the choice of what to prioritize will be one of the first tests of the outgoing leadership’s judgment.
Leadership decisions begin as soon as members return. When lawmakers come back on November 9, chamber and committee leadership contests begin in earnest, and new members start orientation. The outgoing leaders will try to use the session to complete their priorities, while the incoming leaders will try to protect their options for January. The tension between those two goals is the defining feature of every lame-duck session, and it is sharper than usual this year because control of both chambers is changing hands at the same time.
The calendar: session days, breaks and the January 3 handover
The first stretch of the session runs from November 9 to November 20, eight scheduled working days in the House. Then comes the Thanksgiving break, and the House returns on November 30 for 12 more working days until adjourning on December 17. The Senate has 22 scheduled session days in the period, a slightly longer calendar that reflects the chamber’s different rules and workload. The session is expected to run until Christmas, with the understanding that the real deadline is not Christmas but January 3, when the 119th Congress ends and the 120th Congress meets.
January 3, 2027 falls on a Sunday, which adds a small complication. The Twentieth Amendment says Congress’s meeting shall begin at noon on the third day of January unless a law sets a different day, so the new Congress could meet on January 3 or at a later date if lawmakers agree to change the timing through legislation. On the first day, the House calls the roll, elects a Speaker, and swears in its members, and the newly elected senators take the oath. Until that day, the outgoing Speaker remains in place and the outgoing majorities control both chambers.
The funding calendar runs alongside the session calendar. The stopgap spending law signed in September, H.R. 6500, funds most federal programs at the previous year’s levels through December 11, 2026, or earlier for any activity whose full-year fiscal 2027 bill is enacted first. That deadline falls inside the lame-duck session, which means the outgoing Congress must decide what replaces the stopgap: full-year spending bills, another temporary extension, or nothing at all. The decision will be made by the members serving now, not by the members voters have just elected in projections, and it will shape the first weeks of the new Congress as well as the last weeks of the old one.
The unfinished business competing for time
Government funding is not the only item competing for the limited session days. One of the largest pending items is the National Defense Authorization Act for fiscal year 2027. The House passed its version, H.R. 8800, on July 22, 2026, by a vote of 216 to 212, and the Senate received it on September 14. The Senate has not passed either its companion bill or the House bill: a July 14 cloture vote on the motion to proceed to the Senate’s companion bill, S. 4784, failed 50 to 46, and a motion to reconsider remains pending. Before the defense bill can become law, the Senate must act and the two chambers must agree on a single text, which is expected to come together as a compromise negotiated by the Armed Services Committee leaders during the lame-duck session.
The defense bill is only one example. The lame-duck session will also require action, or at minimum another temporary extension, on surface transportation programs, portions of the Farm Bill, and several health care programs. Each of these has its own deadline and its own constituency, and each competes for the same limited floor time. Spending is likely to be top of mind during the period, but it is not the only thing lawmakers have to decide.
There is also the question of who shows up. Republicans have a practical problem in the lame-duck session: getting their own members to attend. Members who lost their races have little incentive to return, and members who are retiring may prefer to spend the time at home. Attendance matters because the House needs a quorum to do business, and close votes can turn on a handful of absences. The outgoing leadership will need to keep its members engaged through the final weeks, even as the political world moves on to the new Congress.
What the lame duck means for the new Congress
For the incoming Democratic majorities, the lame-duck session is a waiting game with real stakes. Every decision the outgoing Congress makes in November and December constrains what the new Congress can do in January. A spending bill that runs through the spring limits the new majority’s ability to set its own priorities. A defense bill passed in the lame duck removes a major item from the new Congress’s agenda. Appointments confirmed in the lame duck, if any are, cannot easily be undone. The new leaders will therefore be watching the session closely, and negotiating where they can, even though they cannot vote.
For the public, the lame-duck session is a reminder that American elections do not produce instant change. The voters spoke on November 3, but the government they chose does not take power until January 3. In between, the government they are replacing still governs, and the decisions it makes in those two months will shape the country the new Congress inherits. The calendar is short, the agenda is long, and the clock runs out at noon on January 3, whether the work is finished or not.
