Yup to account for 0 being Sunday, and if 7 is used for Sunday. PHP uses 0 for Sunday with date('w'). It's in there twice since array numbering starts from 0, so the first Sunday is 0, Monday 1... then on through the 2nd Sunday in which ends up being 7. Which is why you enter the dates with 0-7, it's easy to map to the name that way.
I added a line in the importer to replace any 7's with 0's so then you can use 1-7. The Sunday was in there twice for if you did use 1-7, it would show up properly, but I didn't realize date('w') returns 0 for a Sunday. Here's the fix (at least the schedule view piece, which I also added into schedule_results.tpl for the next):

But any imports should now convert 7s to 0s (as of 932/next update this week)
