Answer 1

You need to group the Person objects by entire days, so let's do:

var res = Model.Persons.OrderByDescending(p => p.Created)
   .GroupBy(p => p.Created.ToShortDateString());

To display them on the console:

foreach(var entry in res)
{
    // Day is the same for all items in a group entry.
    string groupDay = entry.First().Created.ToShortDateString();
    Console.WriteLine(groupDay);

    // list all names of persons in that group
    foreach(Person p in entry)
    {
        Console.WriteLine(p.Name);
    }
}
