I'm trying to add some structured markup to my restaurant listing website using the Structured Markup Helper (highlighting tool) from Google.
When I highlight a restaurant's weekday and opening time, the markup helper tells me that the Day, Month and Year are "required" for an opening time (what?). When I attempt to generate the HTML anyway, the helper displays an error embedded in the markup:
<span itemprop="dayOfWeek" itemscope itemtype="http://schema.org/DayOfWeek"><td itemprop="name">Monday</td></span><td><strong itemprop="opens" content="Please insert valid ISO 8601 date/time here. Examples: 2015-07-27 or 2015-07-27T15:30">8:30am</strong> - <strong itemprop="closes" content="Please insert valid ISO 8601 date/time here. Examples: 2015-07-27 or 2015-07-27T15:30">Midnight</strong></td>
I can't work out the issue. Why would I enter a day/month/year for an opening time? An opening time relates to a weekday, not a day/month/year.
Seems like this guy had the same issue, but the solution wasn't posted.
Help?
