Is there a way to convert the DateObject whose FullForm is:



date1 = DateObject[List[2019,9,14,0,0,0],"Instant","Gregorian",-7.`]


into the following DateObject:



date2 = DateObject[List[2019,9,14],"Day","Gregorian",-7.`]


My list has DateObjects with "Instant" granularity, but I need to use Cases to pick out elements from the same day. I seem to have missed in the documentation how to do this... Thanks for any advice.

          DateObject itself can be used for this:



          date1 // FullForm



          DateObject[List[2019,9,14,0,0,0],"Instant","Gregorian",-7.`]




          DateObject[date1, "Day"] // FullForm



          DateObject[List[2019,9,14],"Day","Gregorian",-7.`]
