The Order of the Companions of Honour is an order of the Commonwealth realms. It was founded on 4 June 1917 by King George V as a reward for outstanding achievements. It was founded on the same date as the Order of the British Empire.

The order was originally intended to be conferred upon a limited number of persons for whom this special distinction seemed to be the most appropriate form of recognition, constituting an honour dissociated from either the acceptance of title or the classification of merit. It is now described as being "awarded for having a major contribution to the arts, science, medicine, or government lasting over a long period of time". The first recipients of the order were all decorated for "services in connection with the war" and were listed in The London Gazette.

Old Style (O.S.) and New Style (N.S.) indicate dating systems before and after a calendar change, respectively. Usually, they refer to the change from the Julian calendar to the Gregorian calendar as enacted in various European countries between 1582 and 1923. Before as well as after the legal change, writers used the dual dating convention to specify a given day by giving its date according to both styles of dating (to ensure that the day concerned was identified unambiguously).

In England, Wales, Ireland, and Britain's American colonies, there were two calendar changes, both in 1752. The first adjusted the start of a new year from 25 March (Lady Day, the Feast of the Annunciation) to 1 January, a change which Scotland had made in 1600. The second discarded the Julian calendar in favour of the Gregorian calendar, skipping 11 days in the calendar for September 1752 to do so.

In the United Kingdom and the British Overseas Territories, personal bravery, achievement, or service are rewarded with honours. The honours system consists of three types of award:

• Honours are used to recognise merit in terms of achievement and service;
• Decorations tend to be used to recognise specific deeds;
• Medals are used to recognise service on a particular operation or in a specific theatre, long or valuable service, and good conduct.

Appointments to the various orders and awards of other honours are usually published in The London Gazette.
