Google has added some timely new properties for event schema. You can now mark your events with these additional properties. These new properties are for the eventStatus property sets under schema.org.
Here is how to use the new properties:
- If the event has been canceled: Set the eventStatus property to EventCancelled and keep the original date in the startDate of the event.
- If the event has been postponed (but the date isn't known yet): Keep the original date in the startDate of the event until you know when the event will take place and update the eventStatus to EventPostponed. The startDate property is required to help identify the unique event, and we need the date original startDate until you know the new date. Once you know the new date information, change the eventStatus to EventRescheduled and update the startDate and endDate with the new date information.
- If the event has been rescheduled to a later date: Update the startDate and endDate with the relevant new dates. Optionally, you can also mark the eventStatus field as EventRescheduled and add the previousStartDate.
- If the event has moved from in-person to online-only: Optionally update the eventStatus field to indicate the change with EventMovedOnline.
