Session is the word used to describe the Parliamentary year. A session begins with the State Opening of Parliament, pre-2012 this usually ran from November to November. From 2012 this occurs in the spring. The session usually runs for the 12 months unless there is a general election. If a general election takes place, the session increases in length to include the additional months from the new date of the State Opening which takes place shortly after the election.
