Hi,
I am using this code to get the day number of the week:
var numbers = entered.split('/');
var daynum = (new Date(Date.UTC(n umbers[2] -
1900,numbers[0],numbers[1]-1))).getUTCDay( );
Date comes in as MM/DD/YYYY
This works fine, as long as I am looking in the same month within a 3
week period. But choose March 1st (Saturday) or any other day in
another month, and the day number is wrong.
6 hours I've been at this....any help would be greatly appreciated. I
just need the day number of the week.
Thank you,

You are doing two nonsensical subtractions, and you have mixed up the
arguments. First, there is no need and it does not make sense to subtract
1900 from the year value. Second, the second argument of Date.UTC() is the
month value; you have to subtract 1 *there*, and _not_ from the value for
the third argument (which is the day-of-month).
Otherwise on 2008-03-01 CE ("3/1/2008") you would end up with
var daynum = (new Date(Date.UTC(1 08, 3, 0)).getUTCDay() ;
The string representation of `new Date(Date.UTC(1 08, 3, 0))' is "Sun Apr 01
0108 02:00:00 GMT+0200" in my Firefox 2.0.0.12; probably not what you want ;-)
6 hours I've been at this....any help would be greatly appreciated. I

If you make the suggested corrections, it should work.

alert(new Date("3/25/2008").getDay() )
alert(new Date(entered).g etDay())

Droll.
>Date comes in as MM/DD/YYYY
FFF.
DS = "03/23/2008"
DoW = (new Date(DS+" GMT").getUTCDay ()+6)%7+1
or if (!(DoW = new Date(DS+" GMT").getUTCDay ())) DoW = 7
will get you the standard result.

Could someone, anyone please tell me what I need to amend, to get this
function to take Sunday as the first day of the week?
I amended the Weekday parts to vbSunday (in my code, not the code
attached), yet when I ran it for 28/09/2003 (UK date format) it
returned Week 39. I would have expected it to return Week 40.
However, I'm really stuck and my head is busting over this, so any
pointers would be gratefully appreciated.
Many thanks...

I need to convert the normal calendar to show the week no., the period no.
and the financial year. The financial year format is as follows:-
Date start: 2 May, 2005
7 days a week, 4 weeks a period and 13 periods a year.
normally 52 weeks per year but one 53-week a year every 6 years. The 53th
week is included in period 13.
Can someone advise any idea how to construct such conversion.

Hello,
Any advice on a function to convert a given week number to a date?
Ideally I'd like the first day of that week.
I'm using this to compare year to year....using the week number as the
common factor.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
