Queen Victoria set a record for a British monarch by reigning for over 63 years and 7 months which was only beaten by Queen Elizabeth II in September 2015. The sovereign’s official birthday was/is still celebrated often on the King’s or Queen’s actual birthday. In 1958, Empire Day became Commonwealth Day which was moved to the second Monday in March and the Monday before May 25th then became significant as Victoria Day, which is also a Canadian holiday.
