1. [Required]
   DateTime? CustomDate {
      get { return date==default(DateTime)?null:date; }
      set { date = value; }
   }
   

2. <%:Html.EditorFor(model => model.CustomDate)%>
   

<td> <div>

<script type="text/javascript">
$(document).ready(function(){
$("#clearme").html("");
});
</script>

<div id="clearme">
<%: Html.EditorFor(model => model.date)%>
</div>

Here

public DateTime DOB { get; set; } 
[Required]
[DisplayFormat(DataFormatString = "{0:yyyy-MM-dd}", ApplyFormatInEditMode = true)]
[DataType(DataType.Date)]
public DateTime? NullableDOB
{
  get => DOB.ToNullable();
  set => DOB = value.DefaultIfNull(); 
}

  => source.Equals(default(T));

        @if(Model.HolidayDate <= DateTime.MinValue)
        {
            @Html.TextBoxFor(model => model.HolidayDate, new { @class = "datepick", @style = "width: 75px;", @id="dataInput"})
