Potentially you could do this by setting the Grid.Row and Grid.Column in the converters.

[ValueConversion(typeof(DateTime), typeof(int))]
public class ColDateFormatter : IValueConverter
{
    #region IValueConverter Members

    public object Convert(object value, Type targetType, 
        object parameter, System.Globalization.CultureInfo culture)
    {
        DateTime startDate = DateTime.Today; // This is just a test to get a date to compare to.
        TimeSpan off = startDate.Subtract(DateTime.Parse(value as string));

        return off.Days + 1;
    }

    public object ConvertBack(object value, Type targetType, object parameter,
        System.Globalization.CultureInfo culture)
    {
        throw new NotImplementedException();
    }

    #endregion
}

<TextBlock Grid.Row="0" Padding="2" 
           Grid.Column="{Binding XPath=Start, Converter={StaticResource ColDateFormatter}}" 
           Text="{Binding Mode=OneWay, XPath=Start, Converter={StaticResource Formatter}, ConverterParameter='dd-MMM-yy'}"/>

The problem that you have is that you are returning the wrong type of value here

public class DateToRowConverter : IValueConverter
{
    public object ConvertTo(object value, Type targetType, object parameter, CultureInfo culture)
    {
       // No checking for simplicity
        return ((DateTime)value).Hour - 8; // Grid starts at 08:00 for example so this provides the necessary offset
    }
    // Rest of class...
}

<Style TargetType="{x:Type ListItem}">
  <Setter PropertyName="Grid.Row" Value="{Binding Path=Start, Converter={StaticResource DateToRowConverter}}" />
  <Setter PropertyName="Grid.Column" Value="{Binding Path=Start, Converter={StaticResource DateToColConverter}}" />
</Style>

<DataTemplate>
  <TextBlock>
    <TextBlock Text="{Binding Path=...}" />
    <TextBlock Text="{Binding Path=...}" />
  </TextBlock>
</DataTemplate>

<Core_WPF:FormNotification WatermarkMessage="New Record" 
    Height="28" Panel.ZIndex="99" AutoCollapseTimeout="2">
    <Core_WPF:FormNotification.ErrorMessage>
        <MultiBinding Converter="{StaticResource formNotificationErrorMessageConverter}">
            <Binding Path="Error" />
