Answer 1

This piece of code give you the exact number of weeks in a given month:

Date.prototype.getMonthWeek = function(monthAdjustement)
{       
    var firstDay = new Date(this.getFullYear(), this.getMonth(), 1).getDay();
    var returnMessage = (Math.ceil(this.getDate()/7) + Math.floor(((7-firstDay)/7)));
    return returnMessage;
}

The monthAdjustement variable adds or substract the month that you are currently in

I use it in a calendar project in JS and the equivalent in Objective-C and it works well
