There shouldn't be any semicolons after the IF and ELSE statements.

BTW I'm not sure if the SWITCH statement is used in a proper/efficient way. In any case you might avoid testing both "January" and "january" by using e.g. the toLowerCase() function: http://www.quirksmode.org/js/strings.html#tocase

It can be confusing for the user to type Yes in the final prompt box (I clicked the Cancel button which didn't work). Use a confirm box instead, then the user can click OK or Cancel without having to type anything.

Also using a DO/WHILE loop seems like a strange solution, I'd rather call function zodiac() again if the user clicked Yes/OK.

Here they are in Unicode: http://www.unicode.org/charts/PDF/U2600.pdf (no idea about the dates). To use them in javascript, I think you can insert a "\u" before the code number, like this for Taurus:

CODE
alert('\u2649');

And if this for an exam you should probably put a Doctype at the very beginning of the page: http://htmlhelp.com/faq/html/basics.html#doctype

Also a valid HTML page needs a HEAD section: http://www.w3.org/TR/html4/struct/global.html#h-7.1
