Maya Astronomy
Maya astronomy is the study of the Moon, planets, Milky Way, Sun, and astronomical phenomena by the Precolumbian era, Precolumbian Maya Civilization of Mesoamerica. The Mesoamerican chronology, Classic Maya in particular developed some of the most accurate pre-telescope astronomy in the world, aided by Maya Script, their fully developed writing system and Maya numerals, their positional numeral system, both of which are fully indigenous to Mesoamerica. The Classic Maya understood many astronomical phenomena: for example, their estimate of the length of the Lunar month#Synodic month, synodic month was more accurate than Ptolemy's, and their calculation of the length of the tropical solar year was more accurate than that of the Spanish when the latter first arrived. Many temples from the Maya architecture have features oriented to celestial events.

American English
American English, sometimes called United States English or U.S. English, is the set of variety (linguistics), varieties of the English language native to the United States. English is the Languages of the United States, most widely spoken language in the United States and in most circumstances is the de facto common language used in government, education and commerce. Since the 20th century, American English has become the most influential form of English worldwide. American English varieties include many patterns of pronunciation, vocabulary, grammar and particularly spelling that are unified nationwide but distinct from other English dialects around the world. Any North American English, American or Canadian accent (sociolinguistics), accent perceived as lacking noticeably local, ethnic or cultural markedness, markers is popularly called General American, "General" or "Standard" American, a fairly uniform dialect continuum, accent continuum native to certain regions of the U ...

Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It was introduced in October 1582 by Pope Gregory XIII as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun. The rule for leap years is: There were two reasons to establish the Gregorian calendar. First, the Julian calendar assumed incorrectly that the average solar year is exactly 365.25 days long, an overestimate of a little under one day per century, and thus has a leap year every four years without exception. The Gregorian reform shortened the average (calendar) year by 0.0075 days to stop the drift of the calendar with respect to the equinoxes.See Wikisource English translation of the (Latin) 1582 papal bull '' Inter gravissimas''.

Madrid Codex (Maya)
The Madrid Codex (also known as the Tro-Cortesianus Codex or the Troano Codex)García Saíz et al. 2010, p. 54. is one of three surviving pre-Columbian Maya books dating to the Postclassic period of Mesoamerican chronology (''circa'' 900–1521 AD). A fourth codex, named the Grolier Codex, was discovered in 1965. The Madrid Codex is held by the Museo de América in Madrid and is considered to be the most important piece in its collection. However, the original is not on display due to its fragility; an accurate reproduction is displayed in its stead. At one point in time the codex was split into two pieces, given the names "Codex Troano" and "Codex Cortesianus". In the 1880s, Leon de Rosny, an ethnologist, realised that the two pieces belonged together, and helped combine them into a single text. This text was subsequently brought to Madrid, and given the name "Madrid Codex", which remains its most common name today. Physical characteristics The Codex was made from a long strip o ...

Dresden Codex
The ''Dresden Codex'' is a Maya civilization, Maya book, which was believed to be the oldest surviving book written in the Americas, dating to the 11th or 12th century. However, in September 2018 it was proven that the Maya Codex of Mexico, previously known as the Grolier Codex, is, in fact, older by about a century. The codex was rediscovered in the city of Dresden, Germany, hence the book's present name. It is located in the museum of the Saxon State and University Library Dresden, Saxon State Library. The codex contains information relating to astronomical and astrological tables, religious references, seasons of the earth, and illness and medicine. It also includes information about conjunctions of planets and moons. The book suffered serious water damage during World War II. The pages are made of amate, high, and can be folded Folded leaflet#Concertina fold, accordion-style; when unfolded the codex is long.

Bishop Diego De Landa
Diego de Landa Calderón, O.F.M. (12 November 1524 – 29 April 1579) was a Spanish Franciscan bishop of the Roman Catholic Archdiocese of Yucatán. Many historians criticize his campaign against idolatry. In particular, he burned almost all the Maya manuscripts (codices) that would have been very useful in deciphering Maya script, knowledge of Maya religion and civilization, and the history of the American continent. Nonetheless, his work in documenting and researching the Maya was indispensable in achieving the current understanding of their culture, to the degree that one scholar asserted that, "ninety-nine percent of what we today know of the Mayas, we know as the result either of what Landa has told us in the pages that follow, or have learned in the use and study of what he told." Conversion of Maya Born in Cifuentes, Guadalajara, Spain, he became a Franciscan friar in 1541, and was sent as one of the first Franciscans to the Yucatán, arriving in 1549. Landa was in c ...

Maní, Yucatán
Maní is a small city in Maní Municipality in the central region of the Yucatán Peninsula, in the Mexican state of Yucatán. It is about 100 km to the south south-east of Mérida, Yucatán, some 16 km east of Ticul. The village of Tipikal lies 6 km to the east.Lougheed. The population is currently around 4000, similar now to the estimated 4500 in the 16th century. History Maní's four millennium existence historically involves mostly its early Maya period, followed in recent centuries by its Spanish conquistador and religious period. Its Mexican period beginning over a century ago involved conflict. Early history Maní has been continuously occupied for approximately 4000 years. In the postclassic Mesoamerican era it was home to the Tutul-Xiu Maya dynasty, which moved their capital here from Uxmal in the 13th century. The Xiu were the dominant power in the western Yucatán after the fall of Mayapan in 1441. Maní served as the main religious center in honor of ...

Amate
Amate ( es, amate from nah, āmatl ) is a type of bark paper that has been manufactured in Mexico since the precontact times. It was used primarily to create codices. Amate paper was extensively produced and used for both communication, records, and ritual during the Triple Alliance; however, after the Spanish conquest, its production was mostly banned and replaced by European paper. Amate paper production never completely died, nor did the rituals associated with it. It remained strongest in the rugged, remote mountainous areas of northern Puebla and northern Veracruz states. Spiritual leaders in the small village of San Pablito, Puebla were described as producing paper with "magical" properties. Foreign academics began studying this ritual use of amate in the mid-20th century, and the Otomi people of the area began producing the paper commercially. Otomi craftspeople began selling it in cities such as Mexico City, where the paper was revived by Nahua painters in Guerrero to c ...

Maya Calendar
The Maya calendar is a system of calendars used in pre-Columbian Mesoamerica and in many modern communities in the Guatemalan highlands, Veracruz, Oaxaca and Chiapas, Mexico. The essentials of the Maya calendar are based upon a system which had been in common use throughout the region, dating back to at least the 5th century BC. It shares many aspects with calendars employed by other earlier Mesoamerican civilizations, such as the Zapotec and Olmec and contemporary or later ones such as the Mixtec and Aztec calendars. By the Maya mythological tradition, as documented in Colonial Yucatec accounts and reconstructed from Late Classic and Postclassic inscriptions, the deity Itzamna is frequently credited with bringing the knowledge of the calendrical system to the ancestral Maya, along with writing in general and other foundational aspects of Mayan culture. Overview The Maya calendar consists of several cycles or ''counts'' of different lengths. The 260-day count is known to s ...

Mesoamerican Long Count Calendar
The Mesoamerican Long Count calendar is a non-repeating, vigesimal (base 20) and octodecimal (base 18) calendar used by several pre-Columbian Mesoamerican cultures, most notably the Maya. For this reason, it is often known as the Maya (or Mayan) Long Count calendar. Using a modified vigesimal tally, the Long Count calendar identifies a day by counting the number of days passed since a mythical creation date that corresponds to August 11, 3114 BCE in the proleptic Gregorian calendar. The Long Count calendar was widely used on monuments. Background The two most widely used calendars in pre-Columbian Mesoamerica were the 260-day Tzolkʼin and the 365-day Haabʼ. The equivalent Aztec calendars are known in Nahuatl as the Tonalpohualli and Xiuhpohualli. The combination of a Haabʼ and a Tzolkʼin date identifies a day in a combination which does not occur again for 18,980 days (52 Haabʼ cycles of 365 days equals 73 Tzolkʼin cycles of 260 days ...

Julian Day
The Julian day is the continuous count of days since the beginning of the Julian period, and is used primarily by astronomers, and in software for easily calculating elapsed days between two events (e.g. food production date and sell by date). The Julian period is a chronological interval of 7980 years; year 1 of the Julian Period was . The Julian calendar year is year of the current Julian Period. The next Julian Period begins in the year . Historians used the period to identify Julian calendar years within which an event occurred when no such year was given in the historical record, or when the year given by previous historians was incorrect. The Julian day number (JDN) is the integer assigned to a whole solar day in the Julian day count starting from noon Universal Time, with Julian day number 0 assigned to the day starting at noon on Monday, January 1, 4713 BC, proleptic Julian calendar (November 24, 4714 BC, in the proleptic Gregorian calendar), a date at whi ...

Greenwich Mean Time
Greenwich Mean Time (GMT) is the Local mean time, mean solar time at the Royal Observatory, Greenwich, Royal Observatory in Greenwich, London, counted from midnight. At different times in the past, it has been calculated in different ways, including being calculated from noon; as a consequence, it cannot be used to specify a particular time unless a context is given. The term 'GMT' is also used as Western European Time, one of the names for the time zone UTC+00:00 and, in UK law, is the basis for civil time in the United Kingdom. English speakers often use GMT as a synonym for Coordinated Universal Time (UTC). For navigation, it is considered equivalent to UT1 (the modern form of mean solar time at 0° longitude); but this meaning can differ from UTC by up to 0.9s. The term GMT should thus not be used for purposes that require precision. Because of Earth's uneven angular velocity in its elliptical orbit and its axial tilt, noon (12:00:00) GMT is rarely the exact moment the S ...

Proleptic Gregorian Calendar
The proleptic Gregorian calendar is produced by extending the Gregorian calendar backward to the dates preceding its official introduction in 1582. In nations that adopted the Gregorian calendar after its official and first introduction, dates occurring in the interim period of 15 October 1582 (the first date of use of Gregorian calendrical dates, being dated 5 October 1582 in the preceding Julian calendar) to the date on which the pertinent nation adopted the Gregorian calendar and abandoned the Julian calendar are sometimes 'Gregorianized' also. For example, the birthday of U.S. President George Washington was originally dated 11 February 1731 (Old Style) because Great Britain, of which he was born a subject, used (until September 1752) the Julian calendar and dated the beginning of English years as 25 March. After Great Britain switched to the Gregorian calendar, Washington's birthday was dated 22 February 1732 proleptically, according to the Gregorian calendar applied backward. ...
