From FDtoys site - create a calendar http://bighugelabs.com/flickr/calendar.php
Wow! This was easy!
At first it was confusing because it did not look like a site to make things. Then I saw a little box that said "jump to" and found their drop down menu and chose "calendar". Not too many choices on how to make the calendar, such as adding important dates, but real easy to make a standard dates page with picture.
