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.

Was the year 1911 a leap year?
No. Leap Years are years that are evenly divisible by 4, such as 1996, 2004, or 2008. There are two exceptions.
Century years that are evenly divisible by 100 are not leap years, unless they are also divisible by 400.
An excellent question in that there was no single person that created leap years.
Throughout the history of civilization many cultures all over the globe created calendars. Most were initially based on the phases of the moon. It was soon discovered, however, that these did not coincide with the length of the years exactly. Slowly, over a period of time, the moons phases fall out of synchronisation.
These cultures, which included the Mayans, Egyptians, Chinese and many others took it upon themselves to calculate just how many days were in a year. Many came to the conclusion that there were approximately 365.25 days in a year. This was remarkably accurate considering the limited technology available at the time.
Some also realised that adding one extra day every four years would tend to correct the error somewhat, though not completely.
The leap year as we know it comes from the Roman calendar which was modified by Julius Caesar (the Julian calendar) and later by Pope Gregory XIII, the Gregorian calendar which is the one much of the world uses today.
What was the first leap year in the 21st century?
January 1st, 2001 not January the 1st 2000, as many people will mistakenly say.
Why is leap year on February the 29th?
each day is not really 24 hours but in fact a bit more so every 4 years we add that time up to be an extra day in february

What is the reason of leap year?
Leap years are necessary because the actual length of a year is 365.242 days, not 365 days, as commonly stated. Basically, leap years occur every 4 years, and years that are evenly divisible by 4 (2004, for example) have 366 days. This extra day is added to the calendar on February 29th.
It did not fit the rules to be a leap year. Leap years are evenly divisible by 4, they are also evenly divisible by 100 but NOT evenly divisible by 400. 1974 is not evenly divisible by 4. 1972 and 1976 were leap years. It is usually only every second even year that is a leap year. So 1970, 1974 and 1978 were not leap years, but 1972, 1976 and 1980 were leap years.
No. If the number of the year is not divisible by 4 (and 1998 is not) it cannot be a leap year. Incidentally, the converse is not strictly true - a year that is divisible by four is nearly but not always a leap year.
The next Christmas that falls on a Tuesday will be in 2012.
The next one after that will be in 2018.
How many days are in January in a leap year?
31 -------------------------------------------
to remember this there is a rhyme: 30 days hath September, April, June and November,
All the rest have 31, excepting February alone.
Which only has but 28 and in a leap year 29.
Where does leap year take place?
According to the Julian calendar, every year that is evenly divisible by four is a leap year.
There are two exceptions to this rule.
1. Years divisible by 100 are not leap years.
2. Years divisible by 400 ARE leap years.
So 2000, 2004 and 2008 were leap years, and 2012 and 2016 will be. However, 2100 will not be, even though 2000 was a leap year.

Why does February have 29 days in a leap year?
1st answer: Because Earth actually takes 365 days and 6 hours to complete its one revolution. So after four years 6 hours change into 24 hours [6*4], meaning 1 day which is added in February as 29th February.
2nd answer: February has 29 days in a leap year for the following reason: A normal year is actually 365 days around 6 hours to be exact 5 hours, 48 minutes and 47 seconds.
To make our calendar system work, we just lump the 6 hours together every 4 years to create the extra day in February, this just happens to be February 29th.
To mange the fact it's not exactly 6 hours for the extra, we adjust for that on the century.
You can use the following algorithm to work out if a year is a leap year or not:
if year is divisible by 400 thenis_leap_year else if year is divisible by 100 then not_leap_year else if year is divisible by 4 then is_leap_year else not_leap_yearThe Earth's yearly voyage around the Sun is not an exact number of days - it is 365.2422 days, or about 365 1/4 days. Therefore, to adapt the calendar to the astronomical reality, every 4 years an extra day is added to the year.
What fraction of one leap year is the month of February?
Approximately 1/52 of a year. There are about 52 weeks in one year.
If the last two digits of the year are divisible by 4, e.g. 1972, then you know it is a leap year. Century years (e.g. 2000) are only leap years if they are divisible by 400.
Leap years occur because a year is not exactly 365 days, but around 365.25 days.
Will leap year always occur every four years?
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.
How many weeks and extra days are there in one leap year?
In a leap year February has four weeks and one day , so a total of 4 1/7 weeks
You would celebrate your birthday on the same day as every other year. So if you were born on the 19th of November in a leap year, then you would celebrate your birthday on the 19th of November in all other years too. The only issue is with someone who is born on the 29th of February. It is the only date in a leap year that does not occur in other years. Some people choose to celebrate their birthday on the 28th of February and some choose to celebrate on the 1st of March. It is really an individual decision.
How many seconds in a non-leap year?
There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day, and 365 days in a year. So if we multiply all these numbers together, we get:
60*60*24*365=31,536,000 seconds
That's over 31 million.
But occasionally they remove or add a second to adjust clocks to the astronomical reality that the rotation of the Earth on it's axis sometimes slows down and sometimes speeds up due to weather and tidal effects.
What is the length of a leap year?
366 days. In a normal year there are 365 days. In the leap year there are there are 29 days in February. A leap year occurs every four years, except years divisible by 100 but NOT 400. For example, 1700, 1800, and 1900 were NOT leap years. 1600 & 2000 WERE leap years.
365 1/4 days in a year
365 and a quarter days every year, that's why we have a leap
year every fourth year to round it up
