Hey @donniepeters,
I believe there’s been a mix up here. We have a “Post Date” smart tag of which the name is dynamically adjusted based on the post type.
For instance, for a post it would say “Post Date”, for a page it would say “Page Date” and so.. for a post type called “Event” it would say “Event Date”. If you read the description for the smart tag inside the tag dropdown, it will say the value is based on the publish date of the post.
In most cases it’s rather clear what the smart tag does but I understand that it is a bit ambiguous in this case.
Unfortunately we currently do not officially integrate with The Events Calendar plugin so we do not have any smart tags that integrate with their plugin, but we can definitely consider this is as a feature request.
