Date.getDay() javascript returns wrong day

Question

Answer 1

I had a similar problem. date.getMonth() returns an index ranging from 0 to 11. January is 0. If you create a new date()-object and you want to get information about a costum date not the current one you have to decrease only the month by 1.

Like this:

function getDayName () {
var year = 2016;
var month = 4;
var day = 11;

var date = new Date(year, month-1, day);
var weekday = new Array("sunday", "monday", "tuesday", "wednesday",
                    "thursday", "friday", "saturday");

return weekday[date.getDay()];
}
