December 1997 Events
December is the twelfth and final month of the year in the Julian calendar, Julian and Gregorian calendars and is also the last of seven months to have a length of 31 days. December got its name from the Latin word ''decem'' (meaning 10 (number), ten) because it was originally the tenth month of the year in the Roman calendar#Legendary 10 month calendar, calendar of Romulus which began in March. The winter days following December were not included as part of any month. Later, the months of January and February were created out of the monthless period and added to the beginning of the calendar, but December retained its name.Macrobius, ''Saturnalia'', tr. Percival Vaughan Davies (New York: Columbia University Press, 1969), book I, chapters 12–13, pp. 89–95.

Julian Calendar
The Julian calendar, proposed by Roman consul Julius Caesar in 46 BC, was a reform of the Roman calendar. It took effect on , by edict. It was designed with the aid of Greek mathematicians and astronomers such as Sosigenes of Alexandria. The calendar became the predominant calendar in the Roman Empire and subsequently most of the Western world for more than 1,600 years until 1582, when Pope Gregory XIII promulgated a minor modification to reduce the average length of the year from 365.25 days to 365.2425 days and thus corrected the Julian calendar's drift against the Tropical year, solar year. adoption of the Gregorian calendar, Worldwide adoption of this revised calendar, which became known as the Gregorian calendar, took place over the subsequent centuries, first in Catholic Church, Catholic countries and subsequently in Protestantism, Protestant countries of the Western Christianity, Western Christian world.

Sol Invictus
Sol Invictus (, "Unconquered Sun"), sometimes simply known as Helios, was long considered to be the official sun god of the later Roman Empire. In recent years, however, the scholarly community has become divided on Sol between traditionalists and a growing group of revisionists. In the traditional view, ''Sol Invictus'' was the second of two entirely different sun gods in Rome. The first of these, ''Sol Indiges'', or ''Sol'', was an early Roman deity of minor importance whose cult had petered out by the first century AD. ''Sol Invictus'', on the other hand, was a Syrian sun god whose cult was first promoted in Rome under Elagabalus, without success. Some fifty years later, on 25 December AD 274, the Roman emperor Aurelian did succeed to establish the cult of ''Sol Invictus'' as an official religion, alongside the traditional Roman cults. Although the Syrian origin of Sol Invictus is undisputed in the traditional view, there has never been consensus on ''which'' Syrian sol ...

Winter
Winter is the coldest season of the year in polar and temperate climates. It occurs after autumn and before spring. The tilt of Earth's axis causes seasons; winter occurs when a hemisphere is oriented away from the Sun. Different cultures define different dates as the start of winter, and some use a definition based on weather. When it is winter in the Northern Hemisphere, it is summer in the Southern Hemisphere, and vice versa. In many regions, winter brings snow and freezing temperatures. The moment of winter solstice is when the Sun's elevation with respect to the North or South Pole is at its most negative value; that is, the Sun is at its farthest below the horizon as measured from the pole. The day on which this occurs has the shortest day and the longest night, with day length increasing and night length decreasing as the season progresses after the solstice. The earliest sunset and latest sunrise dates outside the polar regions differ from the date of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
June
June is the sixth month of the year in the Julian and Gregorian calendars and is the second of four months to have a length of 30 days, and the third of five months to have a length of less than 31 days. June contains the summer solstice in the Northern Hemisphere, the day with the most daylight hours, and the winter solstice in the Southern Hemisphere, the day with the fewest daylight hours (excluding polar regions in both cases). June in the Northern Hemisphere is the seasonal equivalent to December in the Southern Hemisphere and vice versa. In the Northern Hemisphere, the beginning of the traditional astronomical summer is 21 June (meteorological summer begins on 1 June). In the Southern Hemisphere, meteorological winter begins on 1 June. At the start of June, the sun rises in the constellation of Taurus; at the end of June, the sun rises in the constellation of Gemini. However, due to the precession of the equinoxes, June begins with the sun in the astrological si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
