After the deaths of Carus and his son Numerian on a campaign in Persia, Diocles was proclaimed emperor by the troops, taking the name "Diocletianus". The title was also claimed by Carus's surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus.

During April 1947, the Royal New Zealand Navy (RNZN) experienced a series of non-violent mutinies amongst the enlisted sailors of four ships and two shore bases. Over 20 per cent of the RNZN's enlisted personnel were punished or discharged for their involvement. The main cause was the poor rates of pay compared to the rest of the New Zealand Defence Force and equivalent civilian wages, exacerbated by the release of a long overdue government review which failed to address the issue. Sailors saw the new pay rates as still inferior to the other branches of the military, with the increases being consumed by taxes, inflation, and the cancellation of allowances and benefits. The poor living and working conditions aboard RNZN ships was another issue, compounded by sailors having no effective way to make dissatisfaction known to the higher ranks. Dissatisfaction with peacetime duties and opportunities also contributed, with many sailors locked into enlistment periods of up to 12 years, and demobilisation efforts prioritising those enlisted specifically for the duration of the Second World War.

The only mutiny in the history of the Royal New Zealand Navy begins.

The official language is Faroese, which is partially mutually intelligible with Icelandic. The terrain is rugged, dominated by fjords and cliffs with sparse vegetation and few trees. As a result of their proximity to the Arctic Circle, the islands experience perpetual civil twilight during summer nights and very short winter days; nevertheless, they experience a subpolar oceanic climate and mild temperatures year-round due to the Gulf Stream. The capital, Tórshavn, receives the fewest recorded hours of sunshine of any city in the world at only 840 per year.

From 1942 to 1949, Canada forcibly relocated and incarcerated over 22,000 Japanese Canadians—comprising over 90% of the total Japanese Canadian population—from British Columbia on the grounds of national security. The majority were Canadian citizens by birth and were targeted based on their ancestry. This decision followed the events of the Empire of Japan's war in the Pacific against the Western Allies, such as the invasion of Hong Kong, the attack on Pearl Harbor in Hawaii, and the Fall of Singapore which led to the Canadian declaration of war on Japan during World War II. Similar to the actions taken against Japanese Americans in neighbouring United States, this forced relocation subjected many Japanese Canadians to government-enforced curfews and interrogations, job and property losses, and forced repatriation to Japan.

The Government of Canada repeals Japanese-Canadian internment after seven years.

Television InfraRed Observation Satellite (TIROS) is a series of early weather satellites launched by the United States, beginning with TIROS-1 in 1960. TIROS was the first satellite that was capable of remote sensing of the Earth, enabling scientists to view the Earth from a new perspective: space. The program, promoted by Harry Wexler, proved the usefulness of satellite weather observation, at a time when military reconnaissance satellites were secretly in development or use. TIROS demonstrated at that time that "the key to genius is often simplicity". TIROS is an acronym of "Television InfraRed Observation Satellite" and is also the plural of "tiro" which means "a young soldier, a beginner".

The TIROS-1 satellite transmits the first television picture from space.
