Why the leap year comes once in a four years?

Question

Why the leap year comes once in a four years?

Answer 1

The earth takes 365 days 6 hours 9.5mts to complete its resolution around the Sun which makes a year.To adjust the remaining 6hrs, one extra day is added in february after every fourth year and name is given to  it  as a leap year.

The remaing 9.5 mts, are adjusted in a century,I think.

Answer 2

At one time ... well, actually, for most of human history, there wasn't an extra day added every four years. As strange as it may seem, this was actually a big problem. The trouble being that the calendar would drift in relation to the seasons, and especially with things like the summer and winter solstices. OK, so we have that tiny problem, now add to it the fact the moon was "the month" and you can see that what started as a small problem became a bigger problem.

I'm not sure how the ancient calendars dealt with these problems, but the Hebrews actually had a "leap month" that they would add to their calendar when it drifted too far off course to bring it back in line with reality.

The way we get around it is we have fixed the monthly cycles independently of the moon and add an extra day every 4 years or so, plus throw in the odd second every now and then, just to keep our calendar aligned with the "real world".

Answer 3

because in a year there are not 365 days , actually there are 365 days and 6 hours but we count only 365 days . After 4 years there are 365 days and 6+6+6+6 hours . 6+6+6+6 hours = 1 day . so after 4 years we have 365 days + 1 day = 366 days

Answer 4

Because seasons and astronomical events do not repeat at an exact number of full 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.

Answer 5

I will explain you the answer in simple language

the earth revolves around the sun in 365 1\4 (approximate) days.

So, to make the people understand in whole numbers and not in fractions, so it is not difficult, the 1\4 day of every 4 year is combined to make one day which is equal to 365+1=366 days.

Answer 6

that's because there's a quater day left in Feb. 29 so 4 quaters = 1 so the year becomes full and complete (366 days)

Answer 7

The problem is that the calendar isn't in perfect alignment with the Earth's orbit around the sun. It takes the Earth 265.2422 days to make a full orbit around the sun. But this would be inconvneinet to the calendar. So once every four years we add an extra day to make up for the difference of four times 0.2422 of a day.

Answer 8

1 year = 365 and 1/4 day

after 4 years the 1/4's add up to make that extra day ...

;)

Answer 9

A leap year (or intercalary year) is a year containing one or more extra days (or, in the case of lunisolar calendars, an extra month) in order to keep the calendar year synchronised with the astronomical or seasonal year. For example, in the Gregorian calendar, February has 29 days in a leap year instead of the usual 28 - and consequently, the year lasts 366 days instead of the common 365. Because seasons and astronomical events do not repeat at an exact number of full 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.
