Date Redirect + SSI -- Need help

[End Around]

I am creating a time-based art web site that will show a different html
page depending on the client side local date. I also prefer that the top
page doesn't literally redirect to, say 7.htm for the 7th of May, but
accesses that page via a Server Side Include or JS function. The work
doesn't need a date stamp more complicated than "7.htm".

I only know enough about Javascript to be dangerous. I have tried to
bodge together what I could find online and on usenet without success.
If someone could give me a hand with this, I would be happy to credit
them on the site (whenever it goes live).

Thanks to all who get this far,
Ben

Why do you want to use the client's local date? Using the server's date
would be much easier when you want the client to invoke just a fixed URL
like "art.html".

In that case, you can use PHP or any other server-side language to
determine the date and to display the appropriate page.

Moreover, a server-side solution would be independent of the
JavaScript-ability of the client's browser.

If you really want to use the client date, try

var dat = new Date();
location.href = "path/to/you/html/"+dat.getDay()+".html";

That would call pages like "7.html" on the 7th of May. Another solution
would be

var dat = new Date();
location.href = "path/to/you/html/page.html?day="+dat.getDay();

which calls "page.html?day=7".

If you want to encode the client date to make the fact that the page is
date-driven somewhat less obvious, do some calculations on the date, eg.

var dat = new Date();
var day = dat.getDay()*35+17;
location.href = "path/to/you/html/"+dat.getDay()+".html";

On the server-side, you will have to revert this calculation by taking
the encoded day number, subtracting 17, and dividing by 35.

It would never call for 7.html. Please test code before posting.

It will never do that.

You're not using var day.

the encoded day number, subtracting 17, and dividing by 35.

Not necessarily, if the possible values of day are correctly predicted
and the pages named accordingly.
D.getDate() -> 1..31
D.getDay() -> 0..6
