Following the death of Queen Victoria in 1901, May 24 was made by law to be known as "Victoria Day", a date to remember the late queen, who was deemed the "Mother of Confederation", and, in 1904, the same date was by imperial decree made Empire Day throughout the British Empire. Over the ensuing decades, the official date in Canada of the reigning sovereign's birthday changed through various royal proclamations until the haphazard format was abandoned in 1952. That year, both Empire Day and Victoria Day were, by order-in-council and statutory amendment, respectively, moved to the Monday before May 25 and the monarch's official birthday in Canada was by regular viceregal proclamations made to fall on this same date every year between 1953 and January 31, 1957, when the link was made permanent by royal proclamation. The following year, Empire Day was renamed Commonwealth Day and in 1977 it was moved to the second Monday in March, leaving the Monday before May 25 only as both Victoria Day and the Queen's Birthday.
