Bissextile Year in javascript

[rdellac]

Hello, I would like to know if a year is a bissextile year or not.
Have you an idea, because i would want to do a modulo to know if year is a divisible by 4 .

Thanks a lot

Hi there,

according to wikipedia (see here)
following should do the trick just fine:

var d=new Date().getFullYear(); 
var leap=false;
if(d%4==0 && d%100!=0 || d%400==0) leap=true;

The code must be
if(d%4==0 && d%100!=0 || d%400==0) leap=true;
