Not sure that the algorithm 'randomly' calculates the date but here you

Yeah, I was using http://javascript.internet.com/calendars/ but got tired of
reading source.  I deserve this.

umm


var dayOfWeek = c.getDay();


Nope.
Posting it here got him the answer quicker - and without the 50 tons of
nonsense around the one line of interest :-)
...search engines can never compete with struts users who are easily
distracted by [OT] challenges...

Well, if you want to randomly calculate the day of the week, rand(7)
sounds like a good start :-)

If you'd like to *deterministically* determine the day of the week, try:

d = new Date('October 02, 2003');
var weekday=new 
Array("Sunday","Monday","Tuesday","Wednesday","Thursday","Friday","Saturday");

alert(d.getDay()+ ': ' + weekday(d.getDay() );

Re: [OT] Programming Challenge

2003-01-24 Thread Brian Lee 
Get the current day. Figure out what day of the week it is.
i.e. Today is Jan 24, Fri. Then get the number of days between then and now. 
Then mod it by 7 to get the number of days to shift. This should all be able 
to work in JavaScript.

But I think it might be easier to get a JavaScript Date object and use the 
getDay() method to get the day of the week (0=Sunday).

example:
var myDate = new Date("July 4, 2006");
var iDayOfWeek = myDate.getDay();

You'll find that July 4, 2006 is actually a Tuesday

given a particular date?  E.g., July 4, 2006 = Wednesday.  I need to do 
this

And if you want an underlying algorithm you could check out the source to
Rhino - which probably just uses the java classes - so you could go check
their source, but Im thinking you just want a quick solution

...what with it being Friday morning and a long tedious day ahead before you
can relax ;-)
