Hi
the right word in English is leapyear.
You can use the modulus operator (it shows what's left after you divide the
two values):
function isLeapYear(year) {
if ((year % 4) == 0) {
return true;
} else{
return false;
}
}
Another thing: the rules of a leapyear are a bit more complex than the
simple dividable by 4 as far as i know....
Hope this helps,

Subject: [Javascript] Is integer?
Best group member,
Is there any function that checks if something is an integer? I did not find
one and created this temporary function:
function isInteger(thenumber) {
thenumberceil = Math.ceil(thenumber);
if(thenumberceil>thenumber) return false;
else return true;
}
Why I actually need this is because I need to find out if a year is a "skott
year" (do not know the English word, but the years when February has 29 days
instead of 28). Is there any function for that? I created this temporary
function:
function isSkottYear(y) {
yeardiv = y/4;
if(isInteger(yeardiv)) return true;
else return false;
}
There is probably better ways of doing this, are they?
Best regards,
Peter Lauri
