February
February is the second month of the year in the Julian calendar, Julian and Gregorian calendars. The month has 28 days in common years and 29 in leap years, with the February 29, 29th day being called the ''leap day''. 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 August in the Northern Hemisphere. Pronunciation "February" can be 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 the word is pronounced in the US and in the UK. History The Roman month was named after the Latin term , which means "purific ...

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) compared to a common year. The 366th day (or 13th month) is added to keep the calendar year synchronised with the astronomical year or seasonal year. Since astronomical events and seasons do not repeat in a Natural number, whole number of days, calendars having a constant number of days each year will unavoidably drift over time with respect to the event that the year is supposed to track, such as seasons. By inserting ("Intercalation (timekeeping), intercalating") an additional day—a leap day—or month—a leap month—into some years, the drift between a civilization's dating system and the physical properties of the Solar System can be corrected. An astronomical year lasts slightly less than 365 days. The historic Julian calendar has three common years of 365 days followed by a leap year of 366&nb ...

February 29
February 29 is a '' leap day'' (or "leap year day")—an intercalary date added periodically to create leap years in the Julian and Gregorian calendars. It is the 60th day of a leap year in both Julian and Gregorian calendars, and 306 days remain until the end of the leap year. It is the last day of February in leap years only. It is also the last day of meteorological winter in the Northern Hemisphere and the last day of meteorological summer in the Southern Hemisphere in leap years. In the Gregorian calendar, the standard civil calendar used in most of the world, February 29 is added in each year that is an integer multiple of four, unless it is evenly divisible by 100 but not by 400. For example, 1900 was not a leap year, but 2000 was. The Julian calendar— since 1923 a liturgical calendar—has a February 29 every fourth year without exception. Consequently, February 29 in the Julian calendar, since 1900, falls 13 days later than February 29 in the Gregorian, u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Roman Calendar
The Roman calendar was the calendar used by the Roman Kingdom and Roman Republic. Although the term is primarily used for Rome's pre-Julian calendars, it is often used inclusively of the Julian calendar established by Julius Caesar in 46 BC. According to most Roman accounts, #Romulus, their original calendar was established by their Roman legend, legendary list of kings of Rome, first king Romulus. It consisted of ten months, beginning in spring with March and leaving winter as an unassigned span of days before the next year. These months each had 30 or 31 days and ran for 38 nundinal cycles, each forming a kind of eight-day weeknine days inclusive counting, counted inclusively in the Roman mannerand ending with religious rituals and a Roman commerce, public market. This fixed calendar bore traces of its origin as an observational calendar, observational lunar calendar, lunar one. In particular, the most important days of each monthits kalends, nones (calendar), nones, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It went into effect in October 1582 following the papal bull issued by Pope Gregory XIII, which introduced it as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years slightly differently to make the average calendar year 365.2425 days long rather than the Julian calendar's 365.25 days, thus more closely approximating the 365.2422-day tropical year, "tropical" or "solar" year that is determined by the Earth's revolution around the Sun. The rule for leap years is that every year divisible by four is a leap year, except for years that are divisible by 100, except in turn for years also divisible by 400. For example 1800 and 1900 were not leap years, but 2000 was. There were two reasons to establish the Gregorian calendar. First, the Julian calendar was based on the estimate that the average solar year is exactly 365.25 days long, an overestimate of a li ...

Julian Calendar
The Julian calendar is a solar calendar of 365 days in every year with an additional leap day every fourth year (without exception). The Julian calendar is still used as a religious calendar in parts of the Eastern Orthodox Church and in parts of Oriental Orthodox Churches, Oriental Orthodoxy as well as by the Amazigh, Amazigh people (also known as the Berbers). The Julian calendar was proposed in 46 BC by (and takes its name from) Julius Caesar, as a reform of the earlier Roman calendar, which was largely a lunisolar calendar, lunisolar one. It took effect on , by his edict. Caesar's 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 revised calendar. Ancient Romans typically designated years by the names of ruling consuls; the ''Anno Domini'' system of numbering years was not devised until 525, and became widespread in Europe in the eighth cent ...

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 axial tilt, 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 Migration (ecology), 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 definitions of the seasons. The Northern Hemisphere experiences most direct sunlight during May, June, and July (thus the traditional celebration of Midsummer in June), as the hemisphere faces the Sun. For the Southern Hemisphere it is instead in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the ...

Meteorological Winter
Winter is the coldest and darkest season of the year in temperate and polar 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. Winter typically brings precipitation that, depending on a region's climate, is mainly rain or snow. 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 t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Februarius
''Februarius'', fully ''Mensis Februarius'' ("month of Februa"), was the shortest month of the Roman calendar from which the Julian calendar, Julian and Gregorian calendar, Gregorian month of February derived. It was eventually placed second in order, preceded by ''Ianuarius'' ("month of Janus", January) and followed by ''Martius (month), Martius'' ("month of Mars (mythology), Mars", March (month), 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 pe ...

Lupercalia
Lupercalia, also known as Lupercal, 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 (, ''lýkos''; ), and the worship of ''Lycaean Pan'', assumed to be a Greek equivalent to ...

Meteorological Summer
Summer or summertime is the hottest and brightest of the four temperate seasons, occurring after spring and before autumn. At or centred on the summer solstice, daylight hours are the longest and darkness hours are the shortest, with day length decreasing as the season progresses after the solstice. The earliest sunrises and latest sunsets also occur near the date of the solstice. The date of the beginning of summer varies according to definition, climate, tradition, and culture. When it is summer in the Northern Hemisphere, it is winter in the Southern Hemisphere, and vice versa. Etymology The modern English ''summer'' derives from the Middle English ''somer'', via the Old English ''sumor''. 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 21 June or 21 December.

Ancient Rome
In modern historiography, ancient Rome is the Roman people, Roman civilisation from the founding of Rome, founding of the Italian city of Rome in the 8th century BC to the Fall of the Western Roman Empire, collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), the Roman Republic (50927 BC), and the Roman Empire (27 BC476 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 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 controlled the Italian Peninsula, assimilating the Greece, Greek culture of southern Italy (Magna Graecia) and the Etruscans, Etruscan culture, and then became the dominant power in the Mediterranean region and parts of Europe.
