When was your last leap-year?

2008 was the last leap year; 2012 will be the next one.

Because the year isn't exactly 365 days, we need to add an extra day every 4 years to keep the calendar in synch with the seasons. If there were no leap years, then after a century April would be a winter month and December would be part of autumn.

So we add one day every 4 years, on February 29th. But this isn't exactly right, either, because the year isn't 365.25 days, it is 365.26 days. Over the centuries, it would add up. So instead of adding a leap year in EVERY 4th year, we skip century years; so the year 1800 was not a leap year, and 1900 was not, and 2100 won't be either.

But this STILL isn't completely accurate. So on years that are divisible by 400, we DO have a leap year, even though they are century years. THIS is pretty close; it will be accurate for the next 280 centuries.

So, if a year is divisible by 4 or 400, it is a leap year, but if it is divisible by 100 it is not.

When can there be an Olympics in a year that's not a leapyear?

All of these rules together, you can see that a year is a leap year not only if it is divisible by 4 - it also has to be divisible by 400 if it is a centurial year. So 1700, 1800 and 1900 were not leap years, but 2000 was. So a centurial year that is not divisible by 400 is the only time there can be an Olympics in a year that's not a Leapyear.

The short and easy answer is that you multiply by 365 The more correct answer is that you multiply by 365.25 to take into account the extra day in febrary every 4 years.

Write a program in java to find a leap year?

public class LeapYear { public static void main(String[] args) { int year = Integer.parseInt(args[0]); boolean isLeapYear; // divisible by 4 isLeapYear = (year % 4 == 0); // divisible by 4 and not 100 isLeapYear = isLeapYear && (year % 100 != 0); // divisible by 4 and not 100 unless divisible by 400 isLeapYear = isLeapYear (year % 400 == 0); System.out.println(isLeapYear); } }
