Showing previous en next month of contextual filter

I have a content type with a date field (start and end date, always covers a whole month), an image and a title. I use a view with a contextual filter to get the month from the URL (that looks like text/2015-10, text/2015-09, ...). Contextual filter: Content: Month - start date (field_month). Granularity is set to month.

I now want to make a view block for the previous month and one for the next month. And that is previous or next to the month i get from the contextual filter. I want to use these blocks as a pager to the previous or next month, relative to the month i get from the URL with the contextual filter.

For a simple pager with the text prev and next, I can use pager: Page by date | Position: bottom, format: clean.
But that only gives text, I want to show the title and thumbnail from my view as my pager. But to achieve that, I need 'next month' and 'previous month' relative to the month from my contextual filter.

Is this possible with Date / Date Views ?? Am I missing something?
