day from given date

[heaps21]

I have a date in the form yyyy-mm-dd but need somehow, to return the day of the week from it. Is there any predefined syntax for this? if not, what is the best way to go about it.
Cheers.

You can use JavaScripts Date Function to figure it out

var theDate = newDate(date_variable);

theDay = d.getDay();

now the format of the date_variable is m/d/y

thats handy, cheers... I have tried it and it just doesnt get the date right though!!

I have

var y=2004
var m=3
var d=31

then

var c = new Date(m,d,y)

and no matter what combination i use e.g. y,m,d or m,d,y or m/d/y etc etc i just get completely random dates.

Any idea how I can fix this?
Thanks.
