Article I, Section 5, Clause 4:
Neither House, during the Session of Congress, shall, without the Consent of the other, adjourn for more than three days, nor to any other Place than that in which the two Houses shall be sitting.

In Article I, Section 4, Clause 2, the Framers stipulated when Congress would assemble and begin conducting its official business.1 In Article I, Section 5, Clause 4, the Framers gave the two chambers of Congress—the House of Representatives and the Senate—authority to adjourn.2 The House and Senate can use this power independent of each other subject to the requirement that if one Chamber wants to adjourn for more than three days, it requires the other’s consent.3 If the two houses cannot agree to adjourn, the Constitution gives the President power to adjourn them. 4 Article II, Section 3, provides in part in Case of Disagreement between [the House of Representatives and the Senate], with Respect to the Time of Adjournment, [the President] may adjourn them, to such Time as he shall think proper.5
