@if (Model.CF_DateOfBirth.HasValue)
                                        {
                                            var today = DateTime.Today;
                                            var months = DateTime.Today;
                                            var age = today.Year - Model.CF_DateOfBirth.Value.Year;
                                            var mons = months.Month - Model.CF_DateOfBirth.Val`enter code here`ue.Month;
                                            if (Model.CF_DateOfBirth > today.AddYears(-age) && Model.CF_DateOfBirth>months.AddMonths(-mons))
                                            {
                                                age--; mons--;
                                            }
                                              Date of birth:  @Convert.ToDateTime(Model.CF_DateOfBirth).ToShortDateString().ToString()   ( @ageYears  @mons Months)

                                        }
