XAML Bind One Label to Multiple Model Properties

I'm building a DataTemplate for use in a ListView and I'd like to have a label that is bound to multiple properties on the model.

public class SomeObject {

    public string Name { get; set; }
    public DateTime EffectiveDate { get; set; }
    public DateTime ExpirationDate { get; set; }

}

I would like to make a formatted string of EffectiveDate & ExpirationDate in the same label. So something like:
<Label Text="01/05/2015 - 02/18/2015" />

I have a XAML DataTemplate that looks something like this

    <DataTemplate>
        <ViewCell>
            <ViewCell.View>
                <StackLayout
                    Orientation="Vertical"
                    Padding="10, 10"
                    BackgroundColor="White">

                        <Label Text="{Binding Name}"/>

                        <Label Text="Binding EffectiveDate | ExpirationDate, Format={0} - {1}" />
                </StackLayout>
            </ViewCell.View>
        </ViewCell>
    </DateTemplate>

I would like to do a string format of EffectiveDate & ExpirationDate, but I'm not confident on how to get them in the same label. It seems an IConverter implementation might work, but I'm not 100% sure. I haven't been able to figure out how to pass the binding context to the ICoverter to format multiple properties (or if that's possible).
