Answer 1

I was having a similar problem, using the answers above I got the following working on my site. Might be of help to someone else.

{% for num in (0..site.categories.work.size) %}
    {% assign page2 = site.categories.work[num] %}
    {% if page2.title == page.title and page2.date == page.date %}
        {% assign next_i = forloop.index0 | plus: 1 %}
        {% assign prev_i = forloop.index0 | minus: 2 %}

        {% if next_i == site.categories.work.size %}
            {% assign next_i = 1 %}
        {% endif %}
    {% endif %}
{% endfor %}
