February
February is the second month of the year in the Julian and Gregorian calendars. The month has 28 days in common years or 29 in leap years, with the 29th day being called the ''leap day''. It is the first of five months not to have 31 days (the other four being April, June, September, and November) and the only one to have fewer than 30 days. February is the third and last month of meteorological winter in the Northern Hemisphere. In the Southern Hemisphere, February is the third and last month of meteorological summer (being the seasonal equivalent of what is August in the Northern Hemisphere). Pronunciation "February" is pronounced in several different ways. The beginning of the word is commonly pronounced either as or ; many people drop the first "r", replacing it with , as if it were spelled "Febuary". This comes about by analogy with "January" (), as well as by a dissimilation effect whereby having two "r"s close to each other causes one to change. The ending of th ...

Leap Year
A leap year (also known as an intercalary year or bissextile year) is a calendar year that contains an additional day (or, in the case of a lunisolar calendar, a month) added to keep the calendar year synchronized with the astronomical year or seasonal year. Because astronomical events and seasons do not repeat in a whole number of days, calendars that have a constant number of days in each year will unavoidably drift over time with respect to the event that the year is supposed to track, such as seasons. By inserting (called '' intercalating'' in technical terminology) an additional day or month into some years, the drift between a civilization's dating system and the physical properties of the Solar System can be corrected. A year that is not a leap year is a common year. For example, in the Gregorian calendar, each leap year has 366 days instead of 365, by extending February to 29 days rather than the common 28. These extra days occur in each year that is an integer multi ... [...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 ...

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 ...

Season
A season is a division of the year based on changes in weather, ecology, and the number of daylight hours in a given region. On Earth, seasons are the result of the axial parallelism of Earth's tilted orbit around the Sun. In temperate and polar regions, the seasons are marked by changes in the intensity of sunlight that reaches the Earth's surface, variations of which may cause animals to undergo hibernation or to migrate, and plants to be dormant. Various cultures define the number and nature of seasons based on regional variations, and as such there are a number of both modern and historical cultures whose number of seasons varies. The Northern Hemisphere experiences most direct sunlight during May, June, and July, as the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to ...

Februarius
''Februarius'', fully ''Mensis Februarius'' ("month of Februa"), was the shortest month of the Roman calendar from which the Julian and Gregorian month of February derived. It was eventually placed second in order, preceded by '' Ianuarius'' ("month of Janus", January) and followed by '' Martius'' ("month of Mars", March). In the oldest Roman calendar, which the Romans believed to have been instituted by their legendary founder Romulus, March was the first month, and the calendar year had only ten months in all. ''Ianuarius'' and ''Februarius'' were supposed to have been added by Numa Pompilius, the second king of Rome, originally at the end of the year. It is unclear when the Romans reset the course of the year so that January and February came first. ''Februarius'' was the only month in the pre-Julian calendar to have an even number of days, numbering 28. This was mathematically necessary to permit the year itself to have an odd number of days. Ancient sources derived ''F ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lupercalia
Lupercalia was a pastoral festival of Ancient Rome observed annually on February 15 to purify the city, promoting health and fertility. Lupercalia was also known as ''dies Februatus'', after the purification instruments called ''februa'', the basis for the month named '' Februarius''. Name The festival was originally known as Februa ("Purifications" or "Purgings") after the ' which was used on the day.. It was also known as ' and gave its name variously, as epithet to Juno Februalis, Februlis, or Februata in her role as patron deity of that month; to a supposed purification deity called Februus; and to February ('), the month during which the festival occurred. Ovid connects ' to an Etruscan word for "purging". The name ''Lupercalia'' was believed in antiquity to evince some connection with the Ancient Greek festival of the Arcadian Lykaia, a wolf festival ( grc-gre, λύκος, ''lýkos''; la, lupus), and the worship of ''Lycaean Pan'', assumed to be a Greek equival ...

Meteorological 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 winter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Meteorological Summer
Summer is the hottest of the four temperate seasons, occurring after spring and before autumn. At or centred on the summer solstice, the earliest sunrise and latest sunset occurs, daylight hours are longest and dark hours are shortest, with day length decreasing as the season progresses after the solstice. The date of the beginning of summer varies according to climate, tradition, and culture. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa. Timing From an astronomical view, the equinoxes and solstices would be the middle of the respective seasons, but sometimes astronomical summer is defined as starting at the solstice, the time of maximal insolation, often identified with the 21st day of June or December. By solar reckoning, summer instead starts on May Day and the summer solstice is Midsummer. A variable seasonal lag means that the meteorological centre of the season, which is based on average temperature patterns, ...

Ancient Rome
In modern historiography, ancient Rome refers to Roman people, Roman civilisation from the founding of the city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC) and Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic peoples, Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Roman Italy, Italian Peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually dominated the Italian Peninsula, assimilated the Greece, Greek culture of southern Italy (Magna Grecia) and the Etruscans, Etruscan culture and acquired an Empire that took in much of Europe and the lands and peoples surrounding the Mediterranean Sea. It was among the List of largest empires, largest empires in the a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caristia
In ancient Rome, the Caristia, also known as the Cara Cognatio, was an official but privately observed holiday on February 22, that celebrated love of family with banqueting and gifts. Families gathered to dine together and offer food and incense to the Lares as their household gods. It was a day of reconciliation when disagreements were to be set aside, but the poet Ovid observes satirically that this could be achieved only by excluding family members who caused trouble. Activities and context The Caristia was one of several days in February that honored family or ancestors. It followed the Parentalia, nine days of remembrance which began on February 13 and concluded with the Feralia on February 21, or in the view of some, the Caristia on the next day. For the Parentalia, families visited the tombs of their ancestors and shared cake and wine, both in the form of offerings and as a meal among themselves. The Feralia was a more somber occasion, a public festival of sacrifices and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
