Sunrise is the instant at which the upper edge of the Sun appears above the horizon in the east. Sunrise should not be confused with dawn, which is the (variously defined) point at which the sky begins to lighten, some time before the sun itself appears, ending twilight. Because atmospheric refraction causes the sun to be seen while it is still below the horizon, both sunrise and sunset are, from one point of view, optical illusions. The sun also exhibits an optical illusion at sunrise similar to the moon illusion.

The apparent westward revolution of Sun around the earth after rising out of the horizon is due to the Earth's eastward rotation, a counter-clockwise revolution when viewed from above the North Pole. This illusion is so convincing that most cultures had mythologies and religions built around the geocentric model. This same effect can be seen with near-polar satellites as well.

Sunrise and sunset are calculated from the leading and trailing edges of the Sun, and not the center; this slightly increases the duration of "day" relative to "night". The sunrise equation, however, is based on the center of the sun.

The timing of sunset with respect to longitude time varies with the time of year and the latitude of the viewer's location. The precise local time of sunset depends upon the viewer's precise longitude the time zone of the viewer's location. Small daily changes and noticeable semi-annual changes in timing of sunrise are driven by the axial tilt of Earth and the planet's movement in its annual elliptical orbit around the Sun. Those two factors cause main apparent anomalies in precise timing. And thus, for instance, in the Northern Hemisphere, the latest sunrise does not occur on the winter solstice around December 21, but rather about two weeks later, in early January (influence from the Earth's faster movement near the perihelion which occurs around January 3). Likewise, the earliest sunrise does not fall on the summer solstice around June 21, but occurs earlier in June in the Northern Hemisphere (connected with the slower Earth's movement around the aphelion). Subsequently, there occurs easily noticeable phenomenon of daylight shift, as the length of daylight of each particular day in winter (December in the northern hemisphere) reaches its maximum indeed at the time of the winter solstice, but the sunrises continue to travel still to have their maximum hour in early January while at the same time sunsets occur later and later every day starting from the middle of December. As the result it may appear to stay quite dark in the morning each day till the middle of January while at the same time becoming much brighter and brighter with each passing day starting from as early as the middle of December. As one travels farther from the equator, the times of sunrise and sunset change throughout the year. Even on the equator, sunrise and sunset shift several minutes back and forth through the year, along with solar noon. These effects are plotted using an analemma.

Bagan (Burmese: ပုဂံ; MLCTS: pu.gam, pronounced [pəɡàN]), formerly Pagan, is an ancient city in the Mandalay Division of Burma. Formally titled Arimaddanapura or Arimaddana (the City of the Enemy Crusher) and also known as Tambadipa (the Land of Copper) or Tassadessa (the Parched Land), it was the ancient capital of several ancient kingdoms in Burma. It is located in the dry central plains of the country, on the eastern bank of the Ayeyarwady River, 90 miles (145 km) southwest of Mandalay.

Bagan was submitted to become a UNESCO heritage site but many speculate of politics as partly the reason for the exclusion. UNESCO does not designate Bagan as a World Heritage Site. The main reason given is that the military junta (SPDC) has haphazardly restored ancient stupas, temples and buildings, ignoring original architectural styles and using modern materials which bear little or no resemblance to the original designs. The junta has also established a golf course, a paved highway, and built a 200-foot (61-m) watchtower in the southeastern suburb of Minnanthu.

Burma, officially the Union of Myanmar, is the largest country by geographical area in Indochina (mainland Southeast Asia). The country is bordered by China on the north-east, Laos on the east, Thailand on the south-east, Bangladesh on the west, India on the north-west and the Bay of Bengal to the south-west with the Andaman Sea defining its southern periphery. One-third of Burma's total perimeter, 1,930 kilometres (1,199 mi), forms an uninterrupted coastline.

The country's culture, heavily influenced by neighbours, is based on Theravada Buddhism intertwined with local elements. Burma's diverse population has played a major role in defining its politics, history and demographics in modern times, and the country continues to struggle to mend its ethnic tensions. The military has dominated government since General Ne Win led a coup in 1962 that toppled the civilian government of U Nu. Burma remains under the tight control of the military-led State Peace and Development Council.

Archaeology (sometimes written archæology) or archeology (from Greek ἀρχαιολογία, archaiologia – ἀρχαῖος, arkhaīos, "ancient"; and -λογία, -logiā, "-logy") is the science and humanity that studies historical human cultures through the recovery, documentation, analysis, and interpretation of material culture and environmental data, including architecture, artifacts, biofacts, and landscapes. Archaeology aims to understand humankind through these humanistic endeavors. In the United States the field is commonly considered to be a subset of anthropology, along with physical anthropology, cultural anthropology, and linguistic anthropology, whilst in British and European universities, archaeology is considered as a separate discipline.

Archaeology involves surveyance, excavation and eventually analysis of data collected in order to learn more about the past. There are various different goals to the discipline, including the documentation and explanation of the origins and development of human cultures, understanding culture history, chronicling cultural evolution, and studying human behavior and ecology, for both prehistoric and historic societies. Indeed, archaeology is particularly useful in discovering information about human Prehistory, which comprises over 99% of total human history, due to the lack of written sources for this period and the full reliance on archaeological evidence. However, alongside this it is also used to investigate more recent history, even that reaching back only a few decades.

Southeast Asia (or Southeastern Asia) is a subregion of Asia, consisting of the countries that are geographically south of China, east of India and north of Australia. The region lies on the intersection of geological plates, with heavy seismic and volcanic activity.

Southeast Asia consists of two geographic regions: the Asian mainland (aka. Indochina), and island arcs and archipelagoes to the east and southeast. The mainland section section consists of Burma (Myanmar), Cambodia, Laos, Thailand, Vietnam and Peninsular Malaysia while the maritime section consists of Brunei, East Malaysia, East Timor, Indonesia, Papua New Guinea, the Philippines, and Singapore.

Geographically speaking southern China, Taiwan, Hong Kong and Macau are sometimes grouped in the Southeast Asia subregion,^{[citation needed]} although politically they are rarely grouped as such.^{[citation needed]} Vietnam is culturally and historically tied to East Asia rather than Southeast Asia.^{[citation needed]}
