March
March is the third month of the year in both the Julian and Gregorian calendars. It is the second of seven months to have a length of 31 days. In the Northern Hemisphere, the meteorological beginning of spring occurs on the first day of March. The March equinox on the 20 or 21 marks the astronomical beginning of spring in the Northern Hemisphere and the beginning of autumn in the Southern Hemisphere, where September is the seasonal equivalent of the Northern Hemisphere's March. Origin The name of March comes from '' Martius'', the first month of the earliest Roman calendar. It was named after Mars, the Roman god of war, and an ancestor of the Roman people through his sons Romulus and Remus. His month ''Martius'' was the beginning of the season for warfare, and the festivals held in his honor during the month were mirrored by others in October, when the season for these activities came to a close. ''Martius'' remained the first month of the Roman calendar year perhaps as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 solar year. Worldwide adoption of this revised calendar, which became known as the Gregorian calendar, took place over the subsequent centuries, first in Catholic countries and subsequently in Protestant countries of the Western Christian world. The Julian calendar is still used in parts of the Eastern Orthodox Church and in parts of Oriental Orthodoxy as well as by the Berbers. The Julian calenda ...

March Equinox
The March equinox or northward equinox is the equinox on the Earth when the subsolar point appears to leave the Southern Hemisphere and cross the celestial equator, heading northward as seen from Earth. The March equinox is known as the vernal equinox (spring equinox) in the Northern Hemisphere and as the autumnal equinox in the Southern Hemisphere. On the Gregorian calendar, the northward equinox can occur as early as 19 March or as late as 21 March at 0° longitude. For a common year the computed time slippage is about 5 hours 49 minutes ''later'' than the previous year, and for a leap year about 18 hours 11 minutes ''earlier'' than the previous year. Balancing the increases of the common years against the losses of the leap years keeps the calendar date of the March equinox from drifting more than one day from 20 March each year. The March equinox may be taken to mark the beginning of astronomical spring and the end of astronomical winter in the Northern Hemisphere ...

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''.

Roman Calendar
The Roman calendar was the calendar used by the Roman Kingdom and Roman Republic. The term often includes the Julian calendar established by the reforms of the dictator Julius Caesar and emperor Augustus in the late 1stcenturyBC and sometimes includes any system dated by inclusive counting towards months' kalends, nones, and ides in the Roman manner. The term usually excludes the Alexandrian calendar of Roman Egypt, which continued the unique months of that land's former calendar; the Byzantine calendar of the later Roman Empire, which usually dated the Roman months in the simple count of the ancient Greek calendars; and the Gregorian calendar, which refined the Julian system to bring it into still closer alignment with the tropical year. Roman dates were counted inclusively forward to the next of three principal days: the first of the month (the kalends), a day shortly before the middle of the month (the ides), and eight days—nine, counting inclusively—befo ...

Martius (month)
''Martius'' or ''mensis Martius'' (" March") was the first month of the ancient Roman year until possibly as late as 153 BC. After that time, it was the third month, following '' Februarius'' ( February) and preceding '' Aprilis'' (April). ''Martius'' was one of the few Roman months named for a deity, Mars, who was regarded as an ancestor of the Roman people through his sons Romulus and Remus. March marked a return to the active life of farming, military campaigning, and sailing. It was densely packed with religious observances dating from the earliest period of Roman history. Because of its original position as the first month, a number of festivals originally associated with the new year occurred in March. In the Imperial period, March was also a time for public celebration of syncretic or international deities whose ''cultus'' was spread throughout the empire, including Isis and Cybele. In the agricultural year The ''menologia rustica'' told farmers to expect 12 hours o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Year
New Year is the time or day currently at which a new calendar year begins and the calendar's year count increments by one. Many cultures celebrate the event in some manner. In the Gregorian calendar, the most widely used calendar system today, New Year occurs on January 1 ( New Year's Day, preceded by New Year's Eve). This was also the first day of the year in the original Julian calendar and the Roman calendar (after 153 BC). Other cultures observe their traditional or religious New Year's Day according to their own customs, typically (though not invariably) because they use a lunar calendar or a lunisolar calendar. Chinese New Year, the Islamic New Year, Tamil New Year ( Puthandu), and the Jewish New Year are among well-known examples. India, Nepal, and other countries also celebrate New Year on dates according to their own calendars that are movable in the Gregorian calendar. During the Middle Ages in Western Europe, while the Julian calendar was still in use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spring (season)
Spring, also known as springtime, is one of the four temperate seasons, succeeding winter and preceding summer. There are various technical definitions of spring, but local usage of the term varies according to local climate, cultures and customs. When it is spring in the Northern Hemisphere, it is autumn in the Southern Hemisphere and vice versa. At the spring (or vernal) equinox, days and nights are approximately twelve hours long, with daytime length increasing and nighttime length decreasing as the season progresses until the Summer Solstice in June (Northern Hemisphere) and December (Southern Hemisphere). Spring and "springtime" refer to the season, and also to ideas of rebirth, rejuvenation, renewal, resurrection and regrowth. Subtropical and tropical areas have climates better described in terms of other seasons, e.g. dry or wet, monsoonal or cyclonic. Cultures may have local names for seasons which have little equivalence to the terms originating in Europe. M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mars (mythology)
In ancient Roman religion and myth, Mars ( la, Mārs, ) was the god of war and also an agricultural guardian, a combination characteristic of early Rome. He was the son of Jupiter and Juno, and was pre-eminent among the Roman army's military gods. Most of his festivals were held in March, the month named for him ( Latin ''Martius''), and in October, which began the season for military campaigning and ended the season for farming. Under the influence of Greek culture, Mars was identified with the Greek god Ares,''Larousse Desk Reference Encyclopedia'', The Book People, Haydock, 1995, p. 215. whose myths were reinterpreted in Roman literature and art under the name of Mars. The character and dignity of Mars differed in fundamental ways from that of his Greek counterpart, who is often treated with contempt and revulsion in Greek literature. Mars's altar in the Campus Martius, the area of Rome that took its name from him, was supposed to have been dedicated by Numa, ...

Mamuralia
In ancient Roman religion, the Mamuralia or ''Sacrum Mamurio'' ("Rite for Mamurius") was a festival held on March 14 or 15, named only in sources from late antiquity. According to Joannes Lydus, an old man wearing animal skins was beaten ritually with sticks. The name is connected to Mamurius Veturius, who according to tradition was the craftsman who made the ritual shields (''ancilia'') that hung in the temple of Mars. Because the Roman calendar originally began in March, the ''Sacrum Mamurio'' is usually regarded as a ritual marking the transition from the old year to the new. It shares some characteristics with scapegoat or ''pharmakos'' ritual. The craft of Mamurius According to legend, Mamurius was commissioned by Numa, second king of Rome, to make eleven shields identical to the sacred ''ancile'' that fell from the heavens as a pledge of Rome's destiny to rule the world. The '' ancile'' was one of the sacred guarantors of the Roman state ''( pignora imperii)'', and the re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hilaria
The Hilaria (; Latin "the cheerful ones", a term derived from the borrowed adjective grc, ἱλαρός "cheerful, merry") were ancient Roman religious festivals celebrated on the March equinox to honor Cybele. Origins The term seems originally to have been a name which was given to any day or season of rejoicing. The ''hilaria'' were, therefore, according to Maximus the Confessor either private or public. Among the former, he thinks it the day on which a person married, and on which a son was born; among the latter, those days of public rejoicings appointed by a new emperor. Such days were devoted to general rejoicings and public sacrifices, and no one was allowed to show any symptoms of grief or sorrow. The Romans also celebrated ''hilaria'' as a ''feria stativa'', on March 25, the seventh day before the Calends of April, in honor of Cybele, the mother of the gods; and it is probably to distinguish these ''hilaria'' from those mentioned above, that the '' Augustan History ...

Meteorology
Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather observation networks were formed across broad regions. Prior attempts at prediction of weather depended on historical data. It was not until after the elucidation of the laws of physics, and more particularly in the latter half of the 20th century the development of the computer (allowing for the automated solution of a great many modelling equations) that significant breakthroughs in weather forecasting were achieved. An important branch of weather forecasting is marine weather forecasting as it relates to maritime and coastal safety, in which weather effects also include atmospheric interactions with large bodies of water.
