Note we're using the `call` method (which is equivalent to adding an ERB
file) because we were getting an error calling `render` from the `dates`
method:
```
ActionView::Base#lookup_context delegated to
view_renderer.lookup_context, but view_renderer is nil:
```
It might be because we aren't rendering the
`Adming::Budgets::DurationComponent` but just calling one method, and so
there's no view context in this case.
