    Heaven forbid you repeat yourself or provide a code example.... dickhead. It may be wrong but it works the way I want so until I see an example I am going to keep it this way and move on. I will worry about figuring out what exactly you are talking about later.

    The explanation is spot on, but to expand with code;

    dim someDateString as String = dtPick5.Value.ToString(..

    This creates a text, with the date formatted in some culture.

    dim someDate as DateTime = dtPick5.Value

    Here the value is taken as is, without formatting. It is stored as a decimal value, with "days" in the integer part from a given offset, and the decimal part representing time. It is a format-independant version, and that's how it should be stored. Internally, your application should use DateTime values, and only formatting them as strings when displaying. Saving the value in DateTime type is important; if you use a localized and formatted version tht is actually a string, the computer will have to convert that to a real DateTime for each operation.

      Ah yes, the lazy person's fallback position when you don't get someone else to do your work: abuse.

        You decently cannot insult those who try to help.

          When I save the attendance date from a datetimepicker as a date prior to today's date it records acceptable format but not what I really want. When I select today's date it records a date like this 2020-02-25 08:28:00.946341400. The secondary issue is what I eluded to above. I set the custom format in the form_load to "MM, dd, yyyy" and when I select a date prior to today's date it records the date like this 2020-01-29 08:34:25. Here is the Save Button code

          Dim inserted As Integer = 0
          For Each row As DataGridViewRow In dgvAttend.Rows
          Dim isSelected As Boolean = Convert.ToBoolean(row.Cells("chkbox").Value)
          If isSelected Then
          Access.AddParam("@DTE", dtPick5.Value)
          Access.AddParam("@SID", row.Cells("StudentID").Value)
          Access.AddParam("@LN", row.Cells("LastName").Value)
          Access.AddParam("@FN", row.Cells("FirstName").Value)

                      Access.ExecQuery("INSERT INTO Attend (TrainDate,StudentID,LastName,FirstName) " &
                               "VALUES (@DTE,@SID,@LN,@FN); ")
          
                      inserted = inserted + 1
                  End If
              Next
          
              If inserted > 0 Then
                  MessageBox.Show(String.Format("{0} records inserted.", inserted), "ACJTracker", MessageBoxButtons.OK, MessageBoxIcon.Information)
              End If
          

          Here is the form load

          dtPick5.Format = DateTimePickerFormat.Custom
          dtPick5.CustomFormat = "MM, dd, yyyy"
          RefreshAttendGrid()

          Here is the refresh Grid

          dtPick5.Format = DateTimePickerFormat.Custom
          dtPick5.CustomFormat = "MM, dd, yyyy"

              ' RUN QUERY
              Access.ExecQuery("SELECT StudentData.StudentID, StudentData.LastName, StudentData.FirstName FROM StudentData ORDER BY StudentID ASC")
          
              ' REPORT & ABORT ON ERRORS
              If NoErrors(True) = False Then Exit Sub
          
              dgvAttend.DataSource = Access.DBDT
          

          Does anyone know how I correct these issues?

          Weird since examples seem to work with a single comma. You could try to escape extra characters (i.e., commas):

          dtPick5.CustomFormat = "MM',' dd',' yyyy"

          or keep using a more common form.

            It's the VB forum; it looks like a frustrated coder. Don't take it as a personal insult.

                I think the issue you may be facing is that you are storing the data as datetime which naturally includes the time component. If you do not need the time component then you should store it as a date data type (not sure if Access has such a data type). If the is a requirement for the time component then you need to format every instance of the data as it is presented and you need to cater for the time component in all your queries ie you can no longer query for a date you will need to query for the range of datetime records between midnight and midnight the date after.

                    The trouble with some of these people is that they will not accept advice. So no matter how much you try to help them they insist on doing it their way, without understanding the potential problems that can come back to bite them.
