A bissextile is a leap year - a year containing an extra day.
A bissextile month is a month which contains an extra day in a leap year.
Leap year, bissextile year, intercalary year.
Année bissextile is a French equivalent to the title of the movie 'Leap Year'. The feminine noun 'année' means 'year long'. The adjective 'bissextile' refers to a number or a sum that can be divided by the number 'four'. Together, they're pronounced 'ah-neh bee-seh-steel'.
A bissextile year, more commonly known as a leap year, is a year that contains an extra day, February 29th. Leap years occur every four years to help align the calendar year with the solar year, which is about 365.25 days long. This extra day is added to compensate for the slight discrepancy between the two.

There were. 1972 and 1976 were intercalary years (leap years), as was 1980. Such years are sometimes called bissextile years.

Early Julian calendarThe 13th century scholar Sacrobosco claimed that in the Julian calendar February had 30 days in leap years between 45 BC and 8 BC, when Augustus shortened February to give the month of August named after him the same length as the month of July named after his adoptive father Julius Caesar. In fact, if ordinary February 24 was ante diem sextum Kalendas (the sixth day before the beginning of March, February 28 was ante diem secundum Kalendas (the second day before the beginning of March), while February 29 was ante diem (primum) Kalendas (the day before the beginning of March). During leap years, the extraordinary day was added after Febrauary 24, being called ante diem bis sextum Kalendas (the second sixth day before the beginning of March) from whom derived the word bis-sextum which was used to indicate leap years in Neo-Latin languages (French: année bissextile, Spanish: año bisiesto, Italian: anno bisestile).
ANS: A leap year (or intercalary year) is a year containing one or more extra days (or, in the case oflunisolar calendars, an extra month) in order to keep the calendar year synchronized with theastronomical or seasonal year. For example, in the Gregorian calendar, February in a leap year has 29 days instead of the usual 28 so the year lasts 366 days instead of the usual 365. Because seasons and astronomical events do not repeat in a whole number of days, a calendar that 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. A year that is not a leap year is called a common year. February 29 is a date that usually occurs every four years, and is called leap day. This day is added to the calendar in leap years as a corrective measure, because the earth does not orbit around the sun in precisely 365 days. The Gregorian calendar is a modification of the Julian calendar first used by the Romans. The Roman calendar originated as a lunisolar calendarand named many of its days after the syzygies of the moon: the new moon (Kalendae or calends, hence "calendar") and the full moon (Idus or ides). The Nonae or nones was not the first quarter moon but was exactly one nundinae or Roman market week of nine days before the ides, inclusively counting the ides as the first of those nine days. In 1825, Ideler believed that the lunisolar calendar was abandoned about 450 BC by the decemvirs, who implemented the Roman Republican calendar, used until 46 BC. The days of these calendars were counted down (inclusively) to the next named day, so February 24 was ante diem sextum Kalendas Martii ("the sixth day before the calends of March") often abbreviated a. d. VI Kal. Mar. The Romans counted days inclusively in their calendars, so this was actually the fifth day before March 1 when counted in the modern exclusive manner (not including the starting day).[4] The Republican calendar's intercalary month was inserted on the first or second day after the Terminalia (a. d. VII Kal. Mar., February 23). The remaining days of Februarius were dropped. This intercalary month, named Intercalaris or Mercedonius, contained 27 days. The religious festivals that were normally celebrated in the last five days of February were moved to the last five days of Intercalaris. Because only 22 or 23 days were effectively added, not a full lunation, the calends and ides of the Roman Republican calendar were no longer associated with the new moon and full moon. The Julian calendar, which was developed in 46 BC by Julius Caesar, and became effective in 45 BC, distributed an extra ten days among the months of the Roman Republican calendar. Caesar also replaced the intercalary month by a single intercalary day, located where the intercalary month used to be. To create the intercalary day, the existing ante diem sextum Kalendas Martii (February 24) was doubled, producing ante diem bis sextum Kalendas Martii. Hence, the year containing the doubled day was a bissextile (bis sextum, "twice sixth") year. For legal purposes, the two days of the bis sextum were considered to be a single day, with the second half being intercalated, but common practice by 238, when Censorinus wrote, was that the intercalary day was followed by the last five days of February, a. d. VI, V, IV, III and pridie Kal. Mar. (which would be those days numbered 24, 25, 26, 27, and 28 from the beginning of February in a common year), i.e. the intercalated day was the first half of the doubled day. All later writers, including Macrobiusabout 430, Bede in 725, and other medievalcomputists (calculators of Easter), continued to state that the bissextum (bissextile day) occurred before the last five days of February. Until 1970, theRoman Catholic Church always celebrated the feast ofSaint Matthias on a. d. VI Kal. Mar., so if the days were numbered from the beginning of the month, it was named February 24 in common years, but the presence of the bissextum in a bissextile year immediately before a. d. VI Kal. Mar. shifted the latter day to February 25 in leap years, with the Vigil of St. Matthias shifting from February 23 to the leap day of February 24. Other feasts normally falling on February 25-28 in common years are also shifted to the following day in a leap year (although they would be on the same day according to the Roman notation). The practice is still observed by those who use the older calendars.
The Kalends of February would be February 1st.Explanation:The names we use for the months of the year come from the names the Romans used. There are three fixed times in each month, and all dates are given in reference to these fixed times.The first day of each month was called the Kalends (Latin Kalendis).For most months of the year, the fifth day was called the Nones (Latin Nonas) and the thirteenth day was called the Ides (Latin Idus), but in March, May, July and October, the Nones and the Ides were the seventh and fifteenth days.For more (and important) information about the Ides of March, see Related Question below.Additional information:In Roman computation three days in the month were used for counting the date. These three were the Kalends (1st day of the month), the Nones (the 7th day in March, May, July, and October, the 5th in the other months), and the Ides (the 15th day in March, May, July, and October, the 13th in the other months). The days were counted before, not after, the Kalends, Nones, and Ides. Thus, Jan. 10 was the fourth day before the Ides of January or the fourth day of the Ides of January, because the Romans counted inclusively. Jan. 25 was the eighth of the Kalends of February, Feb. 3 was the third of the Nones of February. Feb. 23 was the seventh of the Kalends of March and remained so when an intercalary day was inserted every fourth year between it and Feb. 24; hence in a leap year there were two days counted as the sixth of the Kalends of March. The leap year was therefore called bissextile [Lat.,=sixth twice]. There is a legend that alterations in the length of the months were made later by Augustus to flatter his own vanity, but there seems to be no foundation for this story.
No. The year is only a leap year if it is divisible by 4. However, it is divisible by 100, it must also be divisible by 400 to be a leap year. For example, 2000 was a leap year, but 1900 was not. So 1896 was a leap year and the next leap year was 8 years later, in 1904. 2096 will be a leap year, but 2100 will not be and next will be 2104, so again there is a gap of 8 years. So it is usually, but not always a 4 year gap.
