Roman numerals Numbers in the Roman numeral system

The numeric system represented by Roman numerals originated in ancient Rome and remained the usual way of writing numbers throughout Europe well into the Late Middle Ages. Numbers in this system are represented by combinations of letters from the Latin alphabet. Roman numerals, as used today, employ seven symbols, each with a fixed integer value, as follows:

A leap year is a calendar year containing one additional day added to keep the calendar year synchronized with the astronomical or seasonal year. Because seasons and astronomical events do not repeat in a whole number of days, calendars that have the same number of days in each year drift over time with respect to the event that the year is supposed to track. By inserting an additional day or month into the year, the drift can be corrected. A year that is not a leap year is called a common year.

A leap year starting on Wednesday is any year with 366 days that begins on Wednesday, 1 January, and ends on Thursday, 31 December. Its dominical letters hence are ED, such as the years 1908, 1936, 1964, 1992, 2020, 2048, 2076, and 2116 in the Gregorian calendar or, likewise, 2004 and 2032 in the obsolete Julian calendar. Any leap year that starts on Monday, Wednesday or Thursday has two Friday the 13ths. This leap year contains two Friday the 13ths in March and November. Common years starting on Thursday share this characteristic, but also have another in February.

- Pedro II is declared "of age" prematurely, and begins to reassert central control in Brazil.
- The Province of Canada is created by the Act of Union.
Dom Pedro II, nicknamed "the Magnanimous", was the second and last monarch of the Empire of Brazil, reigning for over 58 years. He was born in Rio de Janeiro, the seventh child of Emperor Dom Pedro I of Brazil and Empress Dona Maria Leopoldina and thus a member of the Brazilian branch of the House of Braganza. His father's abrupt abdication and departure to Europe in 1831 left the five year-old as Emperor and led to a grim and lonely childhood and adolescence, obliged to spend his time studying in preparation for rule. He knew only brief moments of happiness and encountered few friends of his age. His experiences with court intrigues and political disputes during this period greatly affected his later character; he grew into a man with a strong sense of duty and devotion toward his country and his people, yet increasingly resentful of his role as monarch.
The Empire of Brazil was a 19th-century state that broadly comprised the territories which form modern Brazil and Uruguay. Its government was a representative parliamentary constitutional monarchy under the rule of Emperors Dom Pedro I and his son Dom Pedro II. A colony of the Kingdom of Portugal, Brazil became the seat of the Portuguese colonial Empire in 1808, when the Portuguese Prince regent, later King Dom João VI, fled from Napoleon's invasion of Portugal and established himself and his government in the Brazilian city of Rio de Janeiro. João VI later returned to Portugal, leaving his eldest son and heir, Pedro, to rule the Kingdom of Brazil as regent. On 7 September 1822, Pedro declared the independence of Brazil and, after waging a successful war against his father's kingdom, was acclaimed on 12 October as Pedro I, the first Emperor of Brazil. The new country was huge but sparsely populated and ethnically diverse.
The Province of Canada was a British colony in North America from 1841 to 1867. Its formation reflected recommendations made by John Lambton, 1st Earl of Durham in the Report on the Affairs of British North America following the Rebellions of 1837–1838.

The ton is a unit of measure. It has a long history and has acquired a number of meanings and uses over the years. It is used principally as a unit of mass. Its original use as a measurement of volume has continued in the capacity of cargo ships and in terms such as the freight ton. It can also be used as a measure of energy, for truck classification, or as a colloquial term.
