our @weekly_date_list;

This allows access to the package variable @weekly_date_list within the current block.

@weekly_date_list = (@weekly_date_list , "$date");

This stringizes $date and then adds it to the end of the @weekly_date_list array. I think that that author probably meant to write:

push @weekly_date_list, $date;
