What is Event structured data for?

It lets search engines understand event details like date, venue and tickets. Google can then surface your event in the dedicated events experience and in result snippets, driving more qualified visits.

How should dates be formatted?

Schema.org expects ISO 8601 date-times, ideally with a time-zone offset such as 2026-09-01T19:00:00-04:00. This builder uses datetime-local inputs and emits ISO strings so the format is always correct.

What is eventAttendanceMode?

It declares whether an event is offline, online, or both, using schema.org URL values. Online and mixed events should also include a VirtualLocation with the streaming URL so Google can label them correctly.

Do I need an offers block?

It is optional but valuable. Adding price, currency, availability and a ticket URL lets search engines show ticket information and a buy link directly in the events module.

Can I mark an event as cancelled?

Yes. The eventStatus field accepts values like EventCancelled, EventPostponed or EventRescheduled. Keeping this accurate prevents users from arriving at a cancelled event.

Event markup that search engines understand

The JSON-LD Event Schema Builder packages your event details into a valid schema.org/Event block. Correct markup makes your concert, webinar or conference eligible for Google’s event experience, where date, location and tickets appear in a tidy card.

How it works

The tool emits a root Event object with name, description, startDate and endDate as ISO 8601 strings produced from the date inputs. The eventAttendanceMode and eventStatus fields use full schema.org URLs. For physical events, the location is a Place with a nested PostalAddress; for online events it becomes a VirtualLocation with the streaming URL; mixed events emit both as an array. The organizer is an Organization and the performer a Person or Organization. When you supply ticket details, an offers Offer object is added with price, priceCurrency, availability and url.

Tips and example

Always include both startDate and endDate — single-day events still benefit from an explicit end. Use a real time-zone offset so the event appears at the right local time for searchers. A minimal online location looks like this:

"location": {
  "@type": "VirtualLocation",
  "url": "https://example.com/livestream"
}
