Thanks to Brandon Kelly's help I now have Events being filtered by my custom date field called eventDate
by doing the following:
{% set day = date(craft.request.getSegment(2)) %}
{% set nextDay = day|date_modify('+1 day') %}
{% set events = craft.entries.eventDate('and, >= '~day|date('Y-m-d')~', <'~nextDay|date('Y-m-d')) %}
I have some links in my side bar that append the appropriate Date to the URL:
<a href="{{ url('events/'~now|date('Y-m-d')) }}">Today</a>
<a href="{{ url('events/'~nextDay|date('Y-m-d')) }}">Tomorrow</a>
And finally I just loop that through like so:
{% for block in events %}{% endfor %}
I hope someone else can find this as handy as I did through Brandon's help!
