  1. Every four years (2004, 2008, etc.)  


  2. leap years occur every 4 years so the next one is 2012, ect

  3. 2004,2008,2012, ... and so on

    and so forth

  4. 2000 was a leap year, no question about it.  You can tell it's leap year because that's when politicians leap out of their seats and scramble for jobs. Leap years happen every 4 years, so the next one will be in 2012.

  5. every 4 years,with an exception every few hundred years

  6. 4 years later 2003

  7. Every 4 years, 2004/08/12/16 etc

  8. 04 08 12 16 20 etc. every for years except 2100 2200 2300 as they don't follow the gregorian rule leap centuries also only fall once every 400 years so three leap years out of every for centuries dont happen we just got lucky and fell on one that did

  9. Leap years occur every four years, so the next would be 2004, 2008, 2012 and so on.

    I think your question is intended to determine when will be the next century year that is a leap year.  It will be 2400.  The century years 2100, 2200 and 2300 are not leap years.

    What about 2800?  It may surprise you to learn that we don't know yet.

    Leap years every four do not precisely recalibrate the solstice, or "Tropical Year" to the calendar.  One leap year in a four year cycle corrects for exactly six hours per year, but the Tropical Year is only 5 hours 49 minutes longer than the calendar year.  These 11 or 12 extra minutes a year begin to pile up.  In a hundred years, the solstice would happen almost 19 hours too early, and over 400 years the discrepancy will reach 3.12 days.  

    To correct this, in 1582 Pope Gregory XIII decreed that three leap days must be taken out of the cycle every four hundred years.  That's why, in the Gregorian calendar, years divisible by 100 but not by 400 (such as 1900 and 2100) are not leap years.  

    The Gregorian reform is still not precise.  Over many centuries, the 3 left-over hours every four hundred years will start to add up.  As long ago as the time of astronomer John Herschel in the early 1800s, it was realized that the Gregorian calendar with its 400-year rule will add one leap year too many to the calendar every 4000 years, 970 instead of the number which is closer to accurate, 969.    

    In 3000 years the solstice will be running one day late.  To correct this, it will eventually be necessary to make a further modification and drop a leap year.  One way to modify the rule would be to make millennial years divisible by 4000 not leap years.  Currently, millennial years that are divisible by 2000 are leap years, such as the years 2000 and 4000.

    An alternative is the way chosen by the Orthodox Church when it adopted the Gregorian calendar.  Under the Orthodox rule, century years which, when divided by 900 yield a remainder that is either 200 or 600, are leap years.  In other words, the Gregorian rule of two leap years in eight century years becomes two leap years in nine century years. In both versions, the years 1900, 2100, 2200, 2300, 2500, 2600 and 2700 are not leap years, but 2000 and 2400 are.  The year 2800 is a leap year under the Gregorian calendar, but not in the Orthodox.  Conversely, 2900 will be an Orthodox leap year.  

    The Orthodox rule has been adopted in Russia and likely will be picked up by the rest of the world in centuries to come.  Although it is less elegant than the 4000-year rule, it has the advantage of making the calendar correction more gradual than an abrupt jolt after letting the discrepancies pile up for 4000 years.

  10. Every 4 years...

  11. 2004

  12. What do you mean if? 2000 was a leap year. If you can count to four, you may work it out.

  13. A leap-year occurs every four years because the length of a year is about 365.25 days. Over a four year period, that adds up to a complete day length, so we added an extra day. This year is a leap year, and after this one, 2012 will be the next leap year, and no, the world isn't going end.

  14. It's every four years,2004 was a leap year and so is 2008.So the next one is 2012.

  15. every four years bud

  16. Leap years occur every four years.  This is because a complete year (the time it takes Earth to travel around the Sun) is actually 365¼ days.  For this reason, every 4 years, an extra day must be added to the year to make it accurate.

    The next leap year, starting from this year, should be 2012.
