How does an application open or close?
http://www.aa.washington.edu/admissions/undergradapp.html "Currently enrolled UW students will be able to apply to the department once the College of Engineering
application opens for the autumn quarter admission process. The
application normally
opens up after the spring quarter grades have been posted to student transcripts. It is typically about the third week of June. The
application then remains open until July 1st, at which time
it closes permanently until the following year. "
An 'application' is a formal request for something. But in the example, the author thinks that an 'application' could open or close. Could it be an error? Maybe it is the application cycle/period that oopens or closes?
