Is it possible, or how to do it - to have bookmark (bookmarklet?) that, when clicking would open new page, that would have 2 parameters calculated based on current date?
For example, today it would open:
http://some.site/page?from=2011-11-01&to=2011-11-28
but in a week it would be
http://some.site/page?from=2011-12-01&to=2011-12-05
