Leap Year
A leap year is a year containing one extra day in order to keep the calendar year synchronized with the astronomical or seasonal year. Typically once every four years, the exceptions can make this tricky to determine.

What year were the Olympics not held in a leap year?
All of the Winter Olympics, since they occur in between leap years. Additionally, the 1900 Olympic Games were not held on a leap year, since 1900 technically was not a leap year.
There are twelve months in a year because the length of a year is determined by how long it takes for the earth
to complete it's orbit around the sun (365 1/4 days).
The moon orbits around the earth about every 29 days - that's a lunar month. If you divide 365 1/4 days by 29 days, you get about 12 1/2 lunar months in a year. So to have an even number of months in the year, days were added to some of the 12 months to get us to the 365 days (366 in leap years) so that we would have an even 12 months (calendar months) in a year
no,the next leap year is 2012!
No, it is not a leap year.
How many days are there in a year and leap year?
365 days are in a normal year, so you add 1 more day and you have 366 days in a year.
How many days are in the last 35 years including leap years?
it is 12,775 because a year is 365 and 365 times 35= 12,775.
The Gregorian calendar, which now serves as the standard calendar for civil use throughout the world, has both common years and leap years. A common year has 365 days and a leap year 366 days, with the extra, or intercalary, day designated as February 29. A leap year occurs every four years to help synchronize the calendar year with the solar year, or the length of time it takes the earth to complete its orbit about the sun, which is about 365¼ days.
The length of the solar year, however, is slightly less than 365¼ days-by about 11 minutes. To compensate for this discrepancy, the leap year is omitted three times every four hundred years.
In other words, a century year cannot be a leap year unless it is divisible by 400. Thus 1700, 1800, and 1900 were not leap years, but 1600, 2000, and 2400 are leap years.
What are your chances of being born on leap day?About 1 in 1,500.
When is the birthday party?If you are born on a Leap Year, do you get your driver's license on February 28th or March 1st? It is an ambiguous question that is decided by each state. Most states, however, consider March 1st the official day. For instance, the Michigan Vehicle Code states that people born on February 29th "are deemed to have been born on March 1st."
How many people were born on leap day?There are about 187,000 people in the US and 4 million people in the world who were born on Leap Day.
The rules for determining a leap yearMost years that can be divided evenly by 4 are leap years.
Exception: Century years are NOT leap years UNLESS they can be evenly divided by 400.
When did leap year originate?The Gregorian calendar is closely based on the Julian calendar, which was introduced by Julius Caesar in 45 BC. The Julian calendar featured a 12-month, 365-day year, with an intercalary day inserted every fourth year at the end of February to make an average year of 365.25 days. But because the length of the solar year is actually 365.242216 days, the Julian year was too long by .0078 days (11 minutes 14 seconds).
This may not seem like a lot, but over the course of centuries it added up, until in the 16th century, the vernal equinox was falling around March 11 instead of March 21. In 1582, Pope Gregory XIII adjusted the calendar by moving the date ahead by 11 days and by instituting the exception to the rule for leap years. This new rule, whereby a century year is a leap year only if divisible by 400, is the sole feature that distinguishes the Gregorian calendar from the Julian calendar.
Following the Gregorian reform, the average length of the year was 365.2425 days, an even closer approximation to the solar year. At this rate, it will take more than 3,000 years for the Gregorian calendar to gain one extra day in error.
What years did Marlin firearms make the Model 883?
I have one that I'm sure I bought in about 1967, I think. I bought mine in 1964 at a Woolco store in Tempe,AZ. AnswerThe 989 (standard model) was made from 1962-1966 The 989M2 (M1-Carbine lookalike) was made from 1966-1979.
How many minutes are there in two years with a leap year?
87,648 hours
(10y * 365d/y + 2d) * 24h/d = 87,648h
Does a leap year have 372 days?
Only in a leap year which is every four years. Most of the time a year is 365 days.
What is your star sign if you were born in a leap year?
That will depend on what date in a leap year you were born on. So you could be any one of the 12 star signs. People born on the 29th of February, the only date in a leap year that does not also exist in other years, are born under the star sign of Pisces.
Which month gets an extra day each leap year?
February. This is because the earth actually takes 365.25 days to rotate the sun, so every four years there is a build up of 1 extra day, hence the extra day in Feb, on the 29th, aka leap year.
_____________________________
The actual time for Earth to orbit the Sun is not 365.25 days, but 365.2422 days. So adding one leap day in every 4 years still leaves an error of about 1 day in a century.
This is why "century" years, years divisible by 100, are NOT leap years; so 1900 was not a leap year, and 2100 won't be. But because even that isn't QUITE accurate, we do need to add a day every 400 years. So 2000 was a leap year, and the year 2400 will be.
This system was proposed by the Council of Trent in 1563, and ratified by Pope Gregory, so this calendar is called the "Gregorian Calendar".
What is the last leap year in this century?
2096 will be a leap year, as it is divisible by 4. 2100 will not be a leap year, as, while it is divisible by 4, as a multiple of 100, it is not divisible also by 400.
The next year that is a multiple of 100 that will be a leap year is 2400.
Was February 1997 a leap year?
No, it was not. 2008 was a leap year, and 2012 will be a leap year.
Leap years are always evenly divisible by 4, except for years ending in "00" which also have to be divisible by 400 in order to have 366 days. The extra day in a leap year is caused because the Earth takes about 365.24 days to circle the Sun, and the leap days minimize the difference between our calendars and the orbital positions of the Earth.

How many years dose is LEap year occur every years?
A leap year occurs every four years. The day when a leap year hasoccurred is on February 29.
Every year is actually 365 and 1/4 days long. So every 4 years they have to add another day so that everything stays in sync. So, every February, they add a an extra day, every 4 years, so that February has 29 days in Leap years and 28 in common years.
