RSVP to an event
When people invite you to events using Google Calendar, these events will automatically appear on your calendar with a question mark. To RSVP directly on your calendar, follow these steps:
- Click on the event title to open the event.
- Select the Yes, Maybe, or No radio button in the Going? section. If you'd like, include a short message in the Add a note box.
- You can also click the Yes, Maybe, or No link from the event popup bubble.
If you'd like to change your attendance status, revisit the event's page and click on Change your response.
You'll also get an email with the text of the invitation. If you're a Gmail user, you can RSVP to the event directly through the email invitation.
As a note, never forward event invitations to others, as they may contain private information. Similarly, clicking Reply or Reply all to the email invitation itself is not recommended.
