In general, the user shouldn't ever have to format the date... it's all
automatically generated.
However, wise users will look at
http://www.tntluoma.com/ethan/daily/index.php?20020701
and realize that they could possibly "look ahead" by manually editing
the URL and going to
http://www.tntluoma.com/ethan/daily/index.php?20020702
That's all I wanted to avoid. I'm using that particular date string
because it works easily with what I am trying to accomplish.
I am surprised, however, that two PHP functions would deal differently
with the way that day#-of-the-year is handled (365 vs 366).
Thanks to all who made suggestions on/off list, I believe I now have it
working.
