Trouble getting entries after a certain date
This code works - I double checked. I had a bug further down in my code.

{% set fwd = entry.eventStartDate|date_modify('+30 min')|date('c') %}

{% set upcomingEvents = craft.entries
  .section('schedule')
  .order('eventStartDate asc')
  .eventStartDate('&gt; ' ~ fwd )
  .limit(5)
  .status('live, pending')
%}
