leap year?

Question

what is leap year???

Answer 1

A Leap Year (or intercalary year) is a year containing an extra day (or, in case of lunisolar calendars, an extra month) in order to keep the calendar year synchronised with the astronomical or seasonal year. For example, February would have 29 days instead of just 28. 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. A year which is not a leap year is called a common year.


The year 2008 is the next leap year. A leap year occurs every four years.

Answer 2

A leap year is one that has 366 days rather than 365 days. It happens once in four years. February has 29 days in a leap year and 28 days in a non leap year

Answer 3

The earth completes it's revolution in 365.242 days or 365 days & 6 hours.
The calendar year as taken contains 365 days. The remaining 6 hours is added after every 4 years. That is because 6 * 4 = 24. 24 hours make a day and this day is added after 4 years. That year contains 366 days instead of usual 365. The extra day is added in the month of february which then has 29 days instead of 28.

That year containing 1 extra day is called a leap year.

Answer 4

Every year 6 hours are saved and after 4 years this makes 1 day which is added to the month of february.Such an year is known as a leap year.The previous one was 2004 and the next one is 2008

Answer 5

A leap 12 months would not take place each 12 months, a leap 12 months happens as quickly as each 4 years. the belief of a leap 12 months is to get closer the calendar, because of the fact an afternoon isn't precisely 24 hours, an afternoon is 24 hours and 2 minutes (or something on the element of that)

Answer 6

A leap year has 366 days

Answer 7

Leap year : 366 days
Feb 29th is the added day
Non leap year : 365 days

Answer 8

A Leap Year (or intercalary year) is a year containing an extra day (or, in case of lunisolar calendars, an extra month) in order to keep the calendar year synchronised with the astronomical or seasonal year. For example, February would have 29 days instead of just 28. 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. A year which is not a leap year is called a common year.

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).

The Gregorian calendar is a modification of the Julian calendar first used by the Romans. The Roman calendar originated as a lunisolar calendar and 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 24 February was ante diem sextum Kalendae 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).[3]

The Republican calendar's intercalary month was inserted immediately after Terminalia (a. d. VII Kal. Mar., February 23) or immediately after Regifugium (a. d. VI Kal. Mar., February 24). This intercalary month, named Intercalaris or Mercedonius, contained 27 days, 22 additional days to which the last five days of February were added. 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.

When Julius Caesar developed the Julian calendar in 46 BC, becoming effective in 45 BC, in addition to distributing an extra ten days among the months of the Roman Republican calendar he 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 Kalendae Martii (February 24) was doubled, hence the year containing the doubled day was a bissextile (twice sixth) year. Which of the two days was the intercalary day and which was the ordinary day is moot. Apparently the second half was originally regarded as the intercalary day, but in 238 Censorinus stated 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), hence he regarded the bissextum as the first half of the doubled day. All later writers, including Macrobius about 430, Bede in 725, and other medieval computists (calculators of Easter), continued to state that the bissextum (bissextile day) occurred before the last five days of February.

Until quite recently, the Roman Catholic Church always celebrated the feast of Saint 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.

Answer 9

which year contains 366 days due to 29 days of February is called Leap Year.

Answer 10

Next year. Leap years coincide with the US Presidential cycle. They are different from ordinary years in that there is a Feb 29th during that year. So why don't we hold our elections on Feb 29?

No idea.
