Regular sessions of the Arizona State Legislature begin on the second Monday of January each year.
Special sessions can be called by the governor or initiated by the legislature itself. If the session is called by the governor, the legislature can only address the specific matters identified in the governor's call. The effective dates of new laws are
usually 90 days after the Legislature adjourns sine die.
The State of Arizona's annual budget begins every July 1 and ends the
following June 30. This fiscal year is named according to the calendar year of its last month.
