Hi!!

IÂ´d like to calculate the week of the year of the a date in javascript that I write when I want calculate this. In vbscript exists a function DatePart that it do the same that IÂ´d like to simulate.
How I could simulate this in Javascript?

Thanks

I would use a server language, preferably PHP. PHP has very explicit date functions.

Coding this would be very difficult in JavaScript.

Does it need to be cilent-side?

Hi,

Think this should do it (just pass it a date as a parameter)...

Code:

function GetWeek(d){
    var targetDate = new Date(d.getFullYear(), d.getMonth(), d.getDate(), 0, 0, 0);
    var dayDiff = (targetDate - new Date(d.getFullYear(), 0, 1, 0, 0, 0)) / (24 * 60 * 60 * 1000);
    return Math.ceil((dayDiff - targetDate.getDay()) / 7) + 1; 
}

Cheers,

Chris
