 * Hi Joe
    when I test my sites in google structured mark up [http://www.google.com/webmasters/tools/richsnippets](http://www.google.com/webmasters/tools/richsnippets)
   I am getting hcalendar mark up errors that I do not understand. **See Warnings
   Below:** hcalendar date-start: 7:00 pm summary: Ladies’ Cards location: Error:
   We did not accept “7:00 pm” as the start date Error: Date should be in ISO 8601
   format – [http://www.w3.org/TR/NOTE-datetime](http://www.w3.org/TR/NOTE-datetime)
 * How can I fix this ISO format warning?
    ~Thank you

 * At one point (when I first set this up), Google took an attribute value for that
   structured markup. They now require the ISO 8601 value as text, as far as I can
   tell. I haven’t wanted to display that, so I haven’t done it.
 * But this isn’t something I’ve spent time on recently, and I’ll take a look at
   the options available now.

 * Thanks Joe,
    I have been paying close attention to mark-up since I believe it
   really helps the SEO of your sites by letting the bot know what you are all about.
   My fear is that at one point google may change the algorithm and tick you for
   incorrect mark-up. I try to stay ahead of the game if i can. Your help is appreciated.
