If you look in the edit history on this page, you will see roughly what I had in mind on the Talk page for the Main page. Frjohnwhiteford 10:23, April 19, 2007 (PDT)
- This syntax won't work for the main page, though, because the main page's feasts are based on an automatic variable that "knows" what day it is and includes the proper template accordingly. If you know how to make the wiki calculate -13 from the date it "knows," then we're in business.
- The main page doesn't include April 19, but rather Template:April 19. Editing April 19 to include Template:April 6 only adjusts April 19 and would not show up on the main page. If, however, you were to edit Template:April 19 to include Template:April 6 (and do the same for all calendar days), the output would be a recursive, endless loop including the entire calendar and repeating infinitely.—Fr.
