No, I made a mistake.  The Solar year is 365 days, & about 11 minutes short of 6 hours?

"Every year divisible by 4 is a leap year. \nBut every year divisible by 100 is NOT a leap year \nUnless the year is also divisible by 400, then it is still a leap year. "\nSo I think that's taken into account already.  More of this article at the below link.\nBut if you wanted to ask about leap years, why did you bring up the Mayan Calendar?

Tuesday wasn't 6-6-6. It was 6-6-2006. Big difference between 2006 and 6, don't you think? In fact, if you do the math, the difference is 2000 (2006 - 6 = 2000). Hence, you'd have to go back 2000 years if you trully wanted to go "straight to Hell" on 6-6-6.\n\nSorry, all of your efforts were wasted.

It's not the length of the second; it's the number of days it takes the earth to go around the sun.  It takes about 365.26 days.  If the second were lengthened, and clocks stayed as they are, eventually it would be dark at noon.

As you know, light year is not a measure of time but the naswer is:\n\n365x24=8760

because it relies to the events which can't be measured metrically anyway. Weeks follow the approximate lunar circle, there's 365 days in a year etc.\n\nalso, imagine we would divide a day into 100 hours. 1 hour would last only 14 minutes, which would be way too few and confusing. \nIf we divided a day into 10 hours, an hour would last 2 hours and 64 minutes. this would probably be too long, and we wouldn't have enough hours to properly determine a time of day...\n\nAn hour was determined as 1/4 of the time when the shadow of a pole travels a 60 degree angle or something... i THINK. I might be wrong on this, high school phisics is a LONG time ago. \nAnyway, it was old Sumerians or Babilonians who determined it like that and ever since it wasn't changed. We're too used to these units now, we can't just change them without causing a massive MESS :D

A leap year is a year with one extra day inserted into February, the leap year is 366 days with 29 days in February as opposed to the normal 28 days. (There are a few past exceptions to this) \n\nLeap years are needed so that the calendar is in alignment with the earth's motion around the sun. \n\nIt takes 365.2422 days for the earth to make one revolution around the sun (the time is takes to orbit the sun).\n\nUsing a calendar with 365 days would result in an error of 0.2422 days or almost 6 hours per year. After 100 years, this calendar would be more than 24 days ahead of the seasons (tropical year), which is not a desirable situation. It is desirable to align the calendar with the seasons, and make the difference as small as possible.\n\nBy adding leap years approximately every 4th year, this difference between the calendar and the seasons can be reduced significantly, and the calendar will follow the seasons much more closely than without leap years.

I'd like to agree with the first answer, because it\n*does* take leap years into account (that's why\nit suggests that each year is 365.25 days).\n\nThe only thing I can add is that I did a google search\non the "length of a year", and it suggests using\nthe following value (which appears to subtract out\nthe 3 out of 4 century years which are NOT leap years\neven though the year is divisible by 4):\n\n365.242199 days\n\nThus another value for hours is: 130*24*265.24199

You suggest a year is 365 days. Wrong.\nA year = 365.24219040 days. (That's why we have leap years)\nThat is important when you want to know in seconds.31556925 s\n\nTh

Hi, \n\nThe sun's orbit is 365.4 days. The actual length changes very little, but with a period of roughly 41,000 years.\n\nHope that helps, \nMatt

A year is 365 days and 6 hours, so if we didn't every four years, our calendars would become off

In the time it takes the Earth to make one turn on its axis relative to the stars, it also moves relative to the Sun. So a day later, the Sun is not in the same spot relative to the stars and the Earth has to rotate for about another 4 minutes to put the Sun back in the same apparent position.  \n\nThe actual length of a Solar days varies during the year, because the Earth's orbit is elliptical, and the orbital speed varies slightly. If you rely on a sundial to tell time, it will run fast and slow by about 15 minutes in the course of a year. Our 24-hour standard day is the average of the variations, and so is called a Mean Solar Day.\n\nThe sidereal day, on the other hand, is precise to a minute fraction of a second - the Earth does wobble a little and is very gradually slowing down besides, so it's not perfectly repeatable.

ummmmm... is this a trick question?  Two more months and two days.  Why?  because that is the way the calendar is.

Apparent solar days have an average length of 24 hours.  However, an individual apparent solar day may actually be almost 20 seconds longer or shorter.\n\nIn addition, note that the apparent solar day is different from the amount of time it takes the Earth to rotate once around its axis, which is called a sidereal day.  That only takes 23 hours, 56 minutes, and 4 seconds.  The additional rotation in the solar day is because the Earth moves around the sun while moving on its axis, and the Earth needs to rotate further to have the Sun in the same position as the day before.
