    public DateTime Created { get; set; }

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);
    }
}

Answer 2

I belive you would want to use groupBy so you can have the results by date :

 var query = Persons.OrderByDescending(c => c.Created).GroupBy(n=> n.Created.ToShortDateString());

 foreach (var d in query)
        {
            Console.WriteLine(d.Key);
            foreach (var names in d)
               Console.WriteLine(names.name);
        }

Answer 3

you can do like:

Persons.OrderBy(p => p.CreatedDate);
