For centuries, English official public documents have been dated by the regnal years of the ruling monarch. Traditionally, parliamentary statutes are referenced by regnal year, e.g. the Occasional Conformity Act of 1711 is officially referenced as "10 Anne c.6" (read as "the sixth chapter of the statute of the parliamentary session that sat in the 10th year of the reign of Queen Anne"). In the event of a second session, or a second Parliament, in the same regnal year the chapter numbering would reset.
