Date range not displayed correctly in weeks view

[qfl...@gmail.com]

Hello,

I have the data presented below (3 date ranges on the same line), but the 3rd range is not displayed correctly in the weeks view. However, if I zoom in or out (days view or months view), the range is displayed correctly. Does anyone have any idea how to fix the weeks view?

Thank you,

Flavius.

It looks like the source of the problem is with the calculation of the week number. I have replaced the original function from "jquery.fn.gantt.js" with the following one and that seems to fix the problem:

Date.prototype.getWeekOfYear = function () {

var ys = new Date(this.getFullYear(), 0, 1);

var sd = new Date(this.getTime());

// Find Thursday of this week starting on Monday

sd.setDate(sd.getDate() + 4 - (sd.getDay() || 7));

return Math.floor(Math.round((sd - ys) / 86400000) / 7) + 1;

};
