week with id "0"

[julbuel]

there seems to be a problem with the week id

for the first week of 2014, it shows 0

and if you have a value that start Jan 01 2013 to Dec 31 2013
it makes something weird, the item take the size of the label inside :

to correct this i've done the following
i changed the getWeekofYear function
Date.prototype.getWeekOfYear = function () {
var ys = new Date(this.getFullYear(), 0, 1);
var sd = new Date(this.getFullYear(), this.getMonth(), this.getDate());
/if (ys.getDay() > 3) {
ys = new Date(sd.getFullYear(), 0, (7 - ys.getDay()));
}/
sd.setDate(sd.getDate() + 4 - (sd.getDay() || 7));
var daysCount = sd.getDayOfYear() - ys.getDayOfYear();
//return (Math.ceil(daysCount / 7));
return Math.ceil((((sd - ys) / 86400000) + 1) / 7)
};

and i changed the getdayforweek function

Date.prototype.getDayForWeek = function () {
var df = new Date(this.valueOf());
df.setDate(df.getDate() - df.getDay());
var dt = new Date(this.valueOf());
/dt.setDate(dt.getDate() + (6 - dt.getDay()));
if ((df.getMonth() === dt.getMonth()) || (df.getMonth() !== dt.getMonth() && dt.getDate() >= 4)) {
return new Date(dt.setDate(dt.getDate() - 3));
} else {
return new Date(df.setDate(df.getDate() + 3));
}/
return new Date(dt.setDate(dt.getDate() + 4 - (dt.getDay() || 7)));
};

@julbuel That works for 2014, but 2015 starts again with week "0".
