Please answer the following question: Information: - Mexico (, modern Nahuatl ), officially the United Mexican States, is a federal republic in the southern half of North America. It is bordered to the north by the United States; to the south and west by the Pacific Ocean; to the southeast by Guatemala, Belize, and the Caribbean Sea; and to the east by the Gulf of Mexico. Covering almost two million square kilometers (over 760,000sqmi), Mexico is the sixth largest country in the Americas by total area and the 13th largest independent nation in the world. With an estimated population of over 120 million, it is the eleventh most populous country and the most populous Spanish-speaking country in the world while being the second most populous country in Latin America. Mexico is a federation comprising 31 states and a federal district that is also its capital and most populous city. Other metropolises include Guadalajara, Monterrey, Puebla, Toluca, Tijuana and Leon. - Monaco, officially the Principality of Monaco, is a sovereign city-state and microstate, located on the French Riviera in Western Europe. France borders the country on three sides while the other side borders the Mediterranean Sea. Monaco has an area of and a population of about 37,800; it is the second smallest and the most densely populated country in the world. Monaco has a land border of , a coastline of , and a width that varies between . The highest point in the country is a narrow pathway named Chemin des Revoires on the slopes of Mont Agel, in the Les Revoires "Ward", which is above sea level. Monaco's most populous "Quartier" is Monte Carlo and the most populous "Ward" is Larvotto/Bas Moulins. Through land reclamation, Monaco's land mass has expanded by twenty percent. Monaco is known as a playground for the rich and famous, due to its tax laws. In 2014, it was noted about 30% of the population was made up of millionaires, more than in Zurich or Geneva. - Athens ("Athina" ) is the capital and largest city of Greece. Athens dominates the Attica region and is one of the world's oldest cities, with its recorded history spanning over 3,400 years, and its earliest human presence starting somewhere between the 11th and 7th millennia BC. Classical Athens was a powerful city-state that emerged in conjunction with the seagoing development of the port of Piraeus, which had been a distinct city prior to its 5th century BC incorporation with Athens. A centre for the arts, learning and philosophy, home of Plato's Academy and Aristotle's Lyceum, it is widely referred to as the cradle of Western civilization and the birthplace of democracy, largely because of its cultural and political impact on the European continent, and in particular the Romans. In modern times, Athens is a large cosmopolitan metropolis and central to economic, financial, industrial, maritime, political and cultural life in Greece. In 2015, Athens was ranked the world's 29th richest city by purchasing power and the 67th most expensive in a UBS study. - The Spanish conquest of the Aztec Empire (begun February 1519) was one of the most significant events in the Spanish colonization of the Americas. - The Julian calendar, proposed by Julius Caesar in 46BC (708 AUC), was a reform of the Roman calendar. It took effect on 1 January 45BC (AUC 709) (shortly before the Roman conquest of Egypt), by edict. It was the predominant calendar in the Roman world, most of Europe, and in European settlements in the Americas and elsewhere, until it was refined and gradually replaced by the Gregorian calendar, promulgated in 1582 by Pope Gregory XIII. The Julian calendar gains against the mean tropical year at the rate of one day in 128 years. For the Gregorian the figure is one day in 3,030 years. The difference in the average length of the year between Julian (365.25 days) and Gregorian (365.2425 days) is 0.002%. - Rome is a city and special "comune" (named "Roma Capitale") in Italy. Rome is the capital of Italy and of the Lazio region. With 2,870,336 residents in , it is also the country's largest and most populated "comune" and fourth-most populous city in the European Union by population within city limits. The Metropolitan City of Rome has a population of 4.3million residents. The city is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of Tiber river. The Vatican City is an independent country geographically located within the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been often defined as capital of two states. - A city-state is a sovereign state that consists of a city and its dependent territories. Historically, this included cities such as Rome, Athens, Carthage, and the Italian city-states during the Renaissancebut today only a handful of sovereign city-states exist, with some disagreement as to which are city-states. A great deal of consensus exists that the term properly applies to Singapore, Monaco, and Vatican City. - Year 1325 (MCCCXXV) was a common year starting on Tuesday (link will display the full calendar) of the Julian calendar. - The State of Mexico is one of the 32 federal entities of Mexico. It is the most populous, as well as the most densely populated state. It is divided into 125 municipalities and its capital city is Toluca de Lerdo. - Mexico - Tenochtitlan ( Spanish : Mexico - Tenochtitlan , Spanish pronunciation : ( mexiko tenottitan ) ) , commonly known as Tenochtitlan ( Classical Nahuatl : Tenchtitlan ( tenottitan ) ) was an Aztec altepetl ( city - state ) located on an island in Lake Texcoco , in the Valley of Mexico . Founded on June 20 of 1325 , it became the capital of the expanding Mexican Empire in the 15th century , until captured by the Spanish in 1521 . At its peak it was the largest city in the Pre-Columbian Americas . It subsequently became a cabecera of the Viceroyalty of New Spain . Today the ruins of Tenochtitlan are located in Mexico City 's downtown . Tenochtitlan was one of two Mexican altepetl ( city - states ) on the island , the other being Tlatelolco . - Singapore, officially the Republic of Singapore, and often referred to as the "Lion City" or the "Little Red Dot", is a sovereign city-state in Southeast Asia, and the world's only island city-state. It lies one degree (137km) north of the equator, south of the southernmost tip of continental Asia and peninsular Malaysia, with Indonesia's Riau Islands to the south. Singapore's territory consists of a diamond-shaped main island along with 62 other islets. Since independence, extensive land reclamation has increased its total size by 23% (130km), and its greening policy has covered the densely populated island with tropical flora, parks and gardens. - The Toltec culture is an archaeological Mesoamerican culture that dominated a state centered in Tula, Hidalgo, Mexico in the early post-classic period of Mesoamerican chronology (ca 9001168 CE). The later Aztec culture saw the Toltecs as their intellectual and cultural predecessors and described Toltec culture emanating from "Tlln" (Nahuatl for Tula) as the epitome of civilization; indeed in the Nahuatl language the word "Tltcatl" (singular) or "Tltcah" (plural) came to take on the meaning "artisan". The Aztec oral and pictographic tradition also described the history of the Toltec Empire, giving lists of rulers and their exploits. - The Valley of Mexico is a highlands plateau in central Mexico roughly coterminous with the present-day Distrito Federal and the eastern half of the State of Mexico. Surrounded by mountains and volcanoes, the Valley of Mexico was a centre for several pre-Columbian civilizations, including Teotihuacan, the Toltec, and the Aztec. The ancient Aztec term "Anahuac (Land Between the Waters) " and the phrase Basin of Mexico are both used at times to refer to the Valley of Mexico. The Basin of Mexico became a well known site that epitomized the scene of early Classic Mesoamerican cultural development as well. - A common year starting on Tuesday is any non-leap year (i.e. a year with 365 days) that begins on Tuesday, 1 January, and ends on Tuesday, 31 December. Its dominical letter hence is F. The most recent year of such kind was 2013 and the next one will be 2019 in the Gregorian calendar or, likewise, 2014 and 2025 in the obsolete Julian calendar, see below for more. - Lake Texcoco was a natural lake within the Anahuac or Valley of Mexico. Lake Texcoco is most well known as where the Aztecs built the city of Tenochtitlan, which was located on an island within the lake. After the Spanish conquest of the Aztec Empire, efforts to control flooding by the Spanish led to most of the lake being drained. The entire lake basin is now almost completely occupied by Mexico City, the capital of the present-day nation of Mexico. What is the relationship between 'tenochtitlan' and '2019'?
