North Dakota Constitution Art. IV, § 7

The terms of members of the legislative assembly begin on the first day of December following their election.

The legislative assembly shall meet at the seat of government in the month of December following the election of the members thereof for organizational and orientation purposes as provided by law and shall thereafter recess until twelve noon on the first Tuesday after the third day in January or at such other time as may be prescribed by law but not later than the eleventh day of January.

No regular session of the legislative assembly may exceed eighty natural days during the biennium. The organizational meeting of the legislative assembly may not be counted as part of those eighty natural days, nor may days spent in session at the call of the governor or while engaged in impeachment proceedings, be counted. Days spent in regular session need not be consecutive, and the legislative assembly may authorize its committees to meet at any time during the biennium. As used in this section, a “natural day” means a period of twenty-four consecutive hours.

Neither house may recess nor adjourn for more than three days without consent of the other house.
