Qualifying period: In 2018, Aug. 1 doesn't fall on a weekend. Nonetheless, I've always thought it, well, interesting that the dates actually overlap by one day.
Suggestion: August 1, 2017 through July 31, 2017.
I don't know if you want to add anything about a second chance entry being a possibility. Might relieve someone's stress at the last minute.
Otherwise, looking good!!
