Leap yearA leap year (or intercalary year) is a year containing an extra day or month in order to keep the calendar year in sync with an astronomical or seasonal year. Seasons and astronomical events do not repeat at an exact number of days, so a calendar which had the same number of days in each year would over time drift with respect to the event it was supposed to track. By occasionally inserting (or intercalating) an additional day or month into the year, the drift can be corrected.
Leap years (which keep the calendar in sync with the year) should not be confused with leap seconds (which keep clock time in sync with the day).
Gregorian calendar
The Gregorian calendar, the current standard calendar in most of the world, adds a 29th day to February in all years evenly divisible by 4, except for century years (those ending in -00), which receive the extra day only if they are evenly divisible by 400. Thus 1996 was a leap year whereas 1999 was not, and 1600, 2000 and 2400 are leap years but 1700, 1800, 1900 and 2100 are not.
The reasoning behind this rule is as follows:
- The Gregorian calendar is designed to keep the vernal equinox on or close to March 21, so that the date of Easter (celebrated on the Sunday after the 14th day of the Moon that falls on or after 21 March) remains correct with respect to the vernal equinox.
- The vernal equinox year is currently about 365.242375 days long.
- The Gregorian leap year rule gives an average year length of 365.2425 days.
This difference of a little over 0.0001 days means that in around 8,000 years, the calendar will be about one day behind where it should be. But in 8,000 years' time the length of the vernal equinox year will have changed by an amount we can't accurately predict (see below). So the Gregorian leap year rule does a good enough job.

Which day is the leap day?
The Gregorian calendar is a modification of the Julian calendar first used by the Romans. The Roman calendar originated as a lunar calendar (though from the 5th century BC it no longer followed the real moon) and named its days after three of the phases of the moon: the new moon (calends, hence "calendar"), the first quarter (nones) and the full moon (ides). Days were counted down (inclusively) to the next named day, so 24 February was ante diem sextum calendas martii ("the sixth day before the calends of March").
Since 45 BC, February in a leap year had two days called "the sixth day before the calends of March". The extra day was originally the second of these, but since the third century it was the first. Hence the term bissextile day for 24 February in a bissextile year.
Where this custom is followed, anniversaries after the inserted day are moved in leap years. For example, the former feast day of Saint Matthias, 24 February in ordinary years, would be 25 February in leap years.
This historical nicety is, however, in the process of being discarded: The European Union declared that, starting in 2000, 29 February rather than 24 February would be leap day, and the Roman Catholic Church also now uses 29 February as leap day. The only tangible difference is felt in countries that celebrate feast days.
Julian calendar
The Julian calendar adds an extra day to February in years divisible by 4.
This rule gives an average year length of 365.25 days. The excess of about 0.0076 days with respect to the vernal equinox year means that the vernal equinox moves a day earlier in the calendar every 130 years or so.
Revised Julian Calendar
The Revised Julian calendar adds an extra day to February in years divisible by 4, except for years divisible by 100 that do not leave a remainder of 200 or 600 when divided by 900. This rule agrees with the rule for the Gregorian calendar until 2799. The first year that dates in the Revised Julian calendar will not agree with the those in the Gregorian calendar will be 2800, because it will be a leap year in the Gregorian calendar but not in the Revised Julian calendar.
This rule gives an average year length of 365.242222… days. This is a very good approximation to the mean tropical year, but because the vernal equinox tropical year is slightly longer, the Revised Julian calendar does not do as good a job as the Gregorian calendar of keeping the vernal equinox on or close to 21 March.
Chinese calendar
The Chinese calendar is lunisolar, so a leap year has an extra month, often called an embolismic month after the Greek word for it. In the Chinese calendar the leap month is added according to a complicated rule, which ensures that month 11 is always the month that contains the northern winter solstice. The intercalary month takes the same number as the preceding month; for example, if it follows the second month then it is simply called "leap second month".
Hebrew calendar
The Hebrew calendar is also lunisolar with an embolistic month. In the Hebrew calendar the extra month is called Adar Alef (first Adar) and is added before Adar, which then becomes Adar Sheni (second Adar). According to the Metonic cycle, this is done seven times every nineteen years, specifically, in years, 3, 6, 8, 11, 14, 17, and 19.
In addition, the Hebrew calendar has postponement rules that postpone the start of the year by one or two days. The year before the postponement gets one or two extra days, and the year whose start is postponed loses one or two days. These postponement rules reduce the number of different combinations of year length and starting day of the week from 28 to 14, and regulate the location of certain religious holidays in relation to the Sabbath.
Hindu Calendar
In the Hindu calendar, which is a lunisolar calendar, the embolismic month is called adhika maas (extra month). It is the month in which the sun is in the same sign of the stellar zodiac on two consecutive dark moons.
Iranian calendar
The Iranian calendar also has a single intercalated day once in every four years, but every 33 years or so the leap years will be five years apart instead of four years apart. The system used is more accurate and more complicated, and is based on the time of the March equinox as observed from Teheran. The 33-year period is not completely regular; every so often the 33-year cycle will be broken by a cycle of 29 or 37 years.
Long term leap year rules
The accumulated difference between the Gregorian calendar and the vernal equinoctial year amounts to 1 day in about 8,000 years. This suggests that the calendar needs to be improved by another refinement to the leap year rule: perhaps by avoiding leap years in years divisible by 8,000.
(The most common such proposal is to avoid leap years in years divisible by 4,000 [http://www.google.com/search?q=%22gregorian+calendar%22+error+%22leap+year%22+4000]. This is based on the difference between the Gregorian calendar and the mean tropical year. Others claim, erroneously, that the Gregorian calendar itself already contains a refinement of this kind [http://www.straightdope.com/mailbag/mleapyr.html].)
However, there is little point in planning a calendar so far ahead because over a timescale of tens of thousands of years the number of days in a year will change for a number of reasons, most notably:
#Precession of the equinoxes moves the position of the vernal equinox with respect to perihelion and so changes the length of the vernal equinoctial year.
#Tidal acceleration from the sun and moon slows the rotation of the earth, making the day longer.
In particular, the second component of change depends on such things as post-glacial rebound and sea level rise due to climate change. We can't predict these changes accurately enough to be able to make a calendar that will be accurate to a day in tens of thousands of years.
Marriage proposal
There is a tradition, said to go back to Saint Patrick and Saint Bridget in 5th century Ireland, whereby women may only make marriage proposals in leap years.
Saint Patrick and the leap year
:Saint Patrick, having driven the frogs out of the bogs was walking along the shores of Lough Neagh, when he was accosted by Saint Bridget in tears, and was told that a mutiny had broken out in the nunnery over which she presided, the ladies claiming the right of popping the question.
:Saint Patrick said he would concede them the right every seventh year, when Saint Bridget threw her arms round his neck, and exclaimed, "Arrah, Pathrick, jewel, I daurn't go back to the girls wid such a proposal. Make it one year in four." Saint Patrick replied, "Bridget, acushla, squeeze me that way again, an' I'll give ye leap-year, the longest of the lot." Saint Bridget, upon this, popped the question to St Patrick himself, who, of course, could not marry: so he patched up the difficulty as best he could with a kiss and a silk gown.
(Source: Evans, Ivor H, Brewer's Dictionary of Phrase and Fable, Cassell, London, 1988)
According to a 1288 law in Scotland, fines were levied if the proposal was refused by the man; compensation ranged from a kiss to a silk gown to soften the blow. Because men felt that put them at too great a risk, the tradition was in some places tightened to restricting female proposals to 29 February.
Birthdays
A person who was born on 29 February may be called a "leapling". In non-leap years they usually celebrate their birthday on 28 February or 1 March.
There are many instances in children's literature where a person's claim to be only a quarter of their actual age turns out be based on counting their leap-year birthdays. A similar device is used in the plot of the Gilbert and Sullivan operetta The Pirates of Penzance.

Rome
Rome (Italian and Latin: Roma) is the capital of Italy and of its Latium region. It is located on the Tiber and Aniene rivers, near the Mediterranean Sea, at . The Vatican City, a sovereign enclave within Rome, is the seat of the Roman Catholic Church and the home of the Pope.
Rome is the largest city and comune in Italy; the comune or municipality is one of the largest in Europe with an area of 1290 square kilometers. Within the city limits, the population is 2,823,807 (2004); almost 4 million live in the general area of Rome as represented by the province of Rome. The current mayor of Rome is Walter Veltroni.
With a GDP of €75 billion (higher than New Zealand's and equivalent to Singapore's — all three have roughly the same population of around 4 million), in the year 2001 the comune of Rome produced 6.5% of Italy's total GDP, the highest rate among all of Italy's cities.
The city's history extends nearly 2,800 years, during which time it has been the seat of ancient Rome (the Roman Kingdom, Roman Republic, Roman Empire), and later the Papal States, Kingdom of Italy and Italian Republic.
History
Demographics
Throughout its long history Rome has been a centre of learning, trade and commerce. The native Italian population have shared their city throughout the ages with migrants from across Europe and the wider world. In ancient times a large proportion of the population were foreign merchants, slaves, officials and their descendants who came from across the wide empire which bore the city's name. Today the population is very diverse with immigrants thought to make up as much as 20% of the population of the city.
Economy
Today Rome has a dynamic and diverse economy concentrating on innovation, technologies, communications and the service sector. They produce 6.5% of the national GDP (more than any other city in the Italy) and continues to grow at a higher rate than those in the rest of the country. Tourism is inevitably one of Rome's chief industries. The city is also a centre for banking, publishing, insurance, fashion, high-tech industries, housing, cinema (particularly at the famous Cinecittà studios, dubbed the "Hollywood on the Tiber"), and the aerospace industries.
Many international headquarters, government ministries, conference centres, sports venues and museums are located in Rome's principal business districts: the E.U.R. (Esposizione Universale Roma); the Torrino (further south from the E.U.R.); the Magliana; the Parco de' Medici-Laurentina and the so-called Tiburtina-valley along the ancient Via Tiburtina.
Transportation

Rome has an intercontinental airport named Leonardo Da Vinci International Airport - FCO, but more commonly known as Fiumicino, which also is Italy's chief airport, and the Giovan-Battista Pastine international airport (commonly referred to as Ciampino Airport), a joint civilian and military airport southeast of the city-center, along the Via Appia, which handles mainly charter flights and regional European flights including some low-cost airlines. A third airport, called Aeroporto dell'Urbe, is located in the north of the city along the ancient Via Salaria and handles mainly helicopters and private flights. A fourth airport, called Aeroporto di Centocelle, in the eastern part of Rome between the Via Prenestina and the Via Casilina, has been abandoned for some years now, but is currently being redeveloped as one of the largest public parks in Rome.
A subway system operates in Rome called the "Metropolitana" or Rome Metro which was opened in 1955. There are 2 lines (A & B), a third (C) and a new branch of the B-line (B1) are under construction, while a fourth line (D) has been planned. The frequent archaeological findings delay underground work.
Today's (2005) total length is 38 km. The two existing lines, A & B, only intersect at one point, Termini Station, the main train station in Rome (which also is the largest train station in Europe, underneath and around which exists now a lively shopping center known as the "Forum Termini" with more than 100 shops of various types).
Other stations includes: Tiburtina (second-largest, which is currently being redeveloped and enlarged to become the main high-speed train hub in the city), Ostiense, Trastevere, Tuscolana, S. Pietro, Casilina, Torricola.
The Rome Metro is part of an extensive transport network made of a tramway network, several suburban and urban lines in and around the city of Rome, plus an "express line" to Fiumicino Airport. Whereas most FS-Regionale lines (Regional State Railways) do provide mostly a suburban service with more than 20 stations scattered throughout the city, the Roma-Lido (starting at Ostiense station), the Roma-Pantano (starting nearby Termini) and the Roma-Nord (starting at Flaminio station) lines offer a metro-like service.
Rome also has a comprehensive bus system. The web site (translated in english) of the [http://www.atac.roma.it/index.asp?lng=2 public transportation company (ATAC)] allows a route to be calculated using the buses and subways. [http://www.atac.roma.it/biglietti/index.asp?COD=320&LNG=2 Metrebus integrated fare system] allows holders of tickets and integrated passes to travel on all companies vehicles, within the validity time of the ticket purchased.
Chronic congestion caused by cars during the 1970s and 1980s led to the banning of unauthorized traffic from the central part of city during workdays from 6.00 a.m to 6 p.m. (this area is officially called Zona a Traffico Limitato, Z.T.L. in short). Heavy traffic due to night-life crowds during week-ends led in recent years to the creation of other Z.T.L.s in the Trastevere and S. Lorenzo districts during the night, and to the experimentation of a new night Z.T.L. also in the city center (plans to create a night Z.T.L. in the Testaccio district as well are underway). In recent years, parking-spaces along the streets in wide areas of the city have been converted to pay-parkings, as new underground parkings spread throughout the city. In spite of all these measures, traffic remains an unsolved problem, as in the rest of the world's cities.
Education
Z.T.L.
Rome continues to be the major education and research center of Italy, with many major universities that offer degrees in all fields. Among the prestigious educational establishments in Rome is the University of Rome La Sapienza (founded 1303), which is Europe’s biggest university with almost 150,000 students. The city is also home to three other public universities: Università degli studi di Roma “Tor Vergata”, more commonly called Roma 2, University of Roma Tre and the Istituto Universitario di Scienze Motorie.
Undisputed as the greatest repository of western art of the last 3,000 years of human history, Rome is home to many foreign academic institutions, as well, such as The American Academy, The British School, The French Institute, The German Archaeological Institute, The Swedish Institute, and The Finnish Institute, The Japan Foundation.
Several private universities are as well located in Rome, as:
- LUISS University (Libera università internazionale degli studi sociali), probably the most prestigious private university in Rome;
- Università Cattolica Del Sacro Cuore, a renowned university in Italy;
- John Cabot University, a private American University;
- LUMSA University (Libera Universita Maria SS. Assunta);
- University of Malta, an International University;
- Libera Università di Roma "Leonardo da Vinci";
- Libera Università Degli Studi "S. Pio V";
- UPTER University;
- I.S.S.A.S. University.
Still located in Rome are the Accademia di Santa Cecilia - the world's oldest academy of music (founded 1584), St. John's University's Rome campus which is located at the Pontificio Oratorio San Pietro, several academies of fine arts, colleges of the church, medical and Health research instituts.

Administrative subdivision of Rome
The Administrative subdivision of Rome consists in the division of the large territory of Rome into 19 Districts.
Province of Rome
Rome is the capital of a province, with an area of 5,352 sq. km, and a total population of 3,700,424 (2001) in 120 comuni. The province can be viewed as the extended metropolitan area of the town of Rome, although in its more peripheral portions, especially to the north, it comprises towns surrounded by firmly rural landscape, just as towns elsewhere thruout Italy.
Markets and shopping areas
Porta Portese
Street market on Sunday mornings, from very early to around 1pm, on the left bank of the Tiber, between Porto Portese and Stazione Trastevere, centred on Via Portuense. The wares are mainly clothes, both old and new. The second-hand clothing stalls are by far the more popular, with the clothes sorted by type (leathers and furs, jeans, coats, children’s clothes, etc) and piled on large tables with everything at the same (low) price. Tables start at 50c, and range up to 20 euro for high-quality leather and fur.
Campo de' Fiori
Campo de' Fiori is one of the oldest markets in Rome, where food and flowers are most frequently found. Though the name literally means "field of flowers," there are no fields in sight; it's in the middle of downtown Rome, off of the Corso Vittorio Emanuele II. The market is open every morning of the week except Sunday. Campo de' Fiori, surrounded by many bars and restaurants, is also a popular destination at night for locals and foreigners alike.
Symbols and trivia
Rome is commonly identified by several proper symbols, including the Colosseum, the she-wolf (Lupa capitolina), the imperial eagle, and the symbols of Christianity. The famous acronym SPQR recalls the ancient age and the unity between Roman Senate and Roman people.
Rome is called "L'Urbe" (The City), "Caput mundi" (head of the world), "Città Eterna" (eternal city), and "Limen Apostolorum" (the threshold of the apostles).
The town's colors are golden yellow and red (garnet): they stand, respectively, for christian and imperial dignities.
Rome has two holidays of its own: April 21 (the founding of Rome), and June 29 (the feast of its patron saints, Peter and Paul). Other locally important dates are December 8 (the Immaculate Conception) and January 6 (Epiphany).
The Grande Raccordo Anulare (commonly shortened "Il GRA" or "Il Raccordo"), which is more than 80 km long, once encircled the city. Rome has since grown past this round motorway, with new districts well beyond it.
Some proverbs about the Eternal City:
- When in Rome, do as the Romans do.
- All roads lead to Rome.
- Rome wasn't built in a day.
During its long history, Rome has always had a scarcity of native inhabitants, so by tradition a "true" Roman is one whose family has lived in Rome for no less than 7 generations: this is the original "Romano de Roma" (in Romanesco, the local dialect of Italian).
For the autonomistic party Lega Nord, Rome is the symbol of the allegedly parasytical Italian central government, crystalized in their slogan Roma ladrona ("Thief Rome").
