    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.

    > }


    Simpler to use an 8-entry array of Sun..Sun, have startAt 0 or 1, and
    add or subtract startAt when indexing?

    ISTM dangerous to assume that all bar NS4 & IE need +1900. There are
    better ways of dealing with that. Read the FAQ; see below.

    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.
