The new format shows links to specific events on the page along with dates and locations. It provides a fast and convenient way for users to determine if a page has events they may be interested in.
If you have event listings on your site, we encourage you to review the events documentation we've prepared to help you get started. Please note, however, that marking up your content is not a guarantee that Rich Snippets will show for your site. Just as we did for previous formats, we will take a gradual approach to incorporating the new event snippets to ensure a great user experience along the way.
Stay tuned for more developments in Rich Snippets throughout the year!
