The format of the pager header can be modified on the date view configuration page admin/config/regional/date-time/date-views. On that page, find the format that you wish to update, in your case Date views day format with year, which by default is l, F j, Y.

Update that value to be F j, Y, since l returns the weekday, and your date will show as you need it.
