Unreasonably long. You need to simplify and neaten it if you want it to
be widely read.

<FAQENTRY> Code posted needs to be executable as transmitted. The
sending agent must not be allowed to wrap lines. </FAQENTRY>

It's helpful to use two spaces per indent level, rather than a tab; an
editor can easily make the change.
if (startAt==0)
{
dayName = new Array ("Sun","Mon","Tue","Wed","Thu","Fri","Sat")
}
else
{
dayName = new Array ("Mon","Tue","Wed","Thu","Fri","Sat","Sun")
}
Simpler to use an 8-entry array of Sun..Sun, have startAt 0 or 1, and
add or subtract startAt when indexing?

function init()
{

if (!ns4)
{

if (!ie)
{
yearNow += 1900
}
ISTM dangerous to assume that all bar NS4 & IE need +1900. There are
better ways of dealing with that. Read the FAQ; see below.

function WeekNbr(n)
{

year = n.getFullYear();
month = n.getMonth() + 1;
if (startAt == 0)
{
day = n.getDate() + 1;
}
else
{
day = n.getDate();
}

a = Math.floor((14-month) / 12);
y = year + 4800 - a;
m = month + 12 * a - 3;
b = Math.floor(y/4) - Math.floor(y/100) + Math.floor(y/400);
J = day + Math.floor((153 * m + 2) / 5) + 365 * y + b - 32045;
d4 = (((J + 31741 - (J % 7)) % 146097) % 36524) % 1461;
L = Math.floor(d4 / 1460);
d1 = ((d4 - L) % 365) + L;
week = Math.floor(d1/7) + 1;

return week;
}
You don't need all that to get Week Number, whether absolute ISO or
American. A method giving ISO week number should also return the Year.
The 4800 should not be needed for dates after 0000-02-29.

In general, secular Gregorian calendar algorithms are liable to be
simplified by starting with Year %= 400.

endDate = new Date (endDate - (24*60*60*1000));
I suspect India has no Summer Time. Your code may fail elsewhere.
If your code needs to be faster, try using UTC methods rather than local
ones.
