1804 ( MDCCCIV ) was a leap year starting on Sunday of the Gregorian calendar and a leap year starting on Friday of the Julian calendar , the 1804th year of the Common Era (CE) and Anno Domini (AD) designations, the 804th year of the 2nd millennium , the 4th year of the 19th century , and the 5th year of the 1800s decade. As of the start of 1804, the Gregorian calendar was 12 days ahead of the Julian calendar, which remained in localized use until 1923.

Roman numerals Numbers in the Roman numeral system

Roman numerals are a numeral system that 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. Modern usage employs seven symbols, each with a fixed integer value:

A leap year is a calendar year containing an 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 Sunday is any year with 366 days that begins on Sunday, 1 January, and ends on Monday, 31 December. Its dominical letters hence are AG, such as the years 1888, 1928, 1956, 1984, 2012, 2040, 2068, 2096, 2108, 2136, 2164, and 2192 in the Gregorian calendar or, likewise, 1996 and 2024 in the obsolete Julian calendar.

Haiti, officially the Republic of Haiti and formerly called Hayti, is a country located on the island of Hispaniola in the Greater Antilles archipelago of the Caribbean Sea, to the east of Cuba and Jamaica and south of The Bahamas and the Turks and Caicos Islands. It occupies the western three-eighths of the island which it shares with the Dominican Republic. To its south-west lies the small island of Navassa Island, which is administered by the United States but claimed by Haiti as part of its territory. Haiti is 27,750 square kilometers (10,714 sq mi) in size and has an estimated population of 10.8 million, making it the most populous country in the Caribbean Community (CARICOM) and the second-most populous country in the Caribbean after Cuba.

A republic is a form of government in which the country is considered a "public matter", not the private concern or property of the rulers. The primary positions of power within a republic are attained through democracy, oligarchy, autocracy, or a mix thereof, rather than being unalterable occupied. It has become the opposing form of government to a monarchy and has therefor no monarch as head of state.
