Get week of the month

Question

How can i get the week number of month using javascript / jquery?

For ex.:

First Week: 5th July, 2010. / Week Number = First monday

Answer 1

This is nothing natively supported.

You could roll your own function for this, working from the first day of the month

var currentDate = new Date();
var firstDayOfMonth = new Date( currentDate.getFullYear(), currentDate.getMonth(), 1 );

And then getting the weekday of that date:

var firstWeekday = firstDayOfMonth.getDay();

... which will give you a zero-based index, from 0-6, where 0 is Sunday.
