You can edit an event any time before it starts. Some changes notify guests; others stay quiet.
Editing
Open the event and tap Edit event in the host bar at the top (or expand Host controls and guests and use the edit shortcut there). You'll get the same three-tab form you created the event with.
What notifies vs what doesn't
| Edit | Notifies guests? |
|---|---|
| Date / start time / end time | Yes, everyone going or maybe |
| Location | Yes, everyone going or maybe |
| Cancellation | Yes, everyone, regardless of RSVP |
| Title, description, cover image, BYO details | Silent |
| Visibility, plus-one settings | Silent |
Publishing a draft sends the queued invites and follower notifications then, not an "event updated" alert. And a live event keeps its original publish date when you edit it.
Cancelling or deleting
Both live in Host controls and guests, in the danger zone at the bottom (creator only).
Open Host controls and guests
On the event page, expand the section and scroll to the danger zone.
Choose Cancel or Delete
Cancelling can carry a message to every guest. Deleting asks you to confirm because it's permanent.
Cancel vs delete
| Cancel | Delete | |
|---|---|---|
| Notifies guests | Yes | No |
| Event URL stays valid | Yes (shows "cancelled") | No (404) |
| Reversible | No, but the page stays up marked as cancelled | No |
| Use for | Plans that fell through | Accidental duplicates, test events |
Deletion is irreversible, don't make it your default for plans that fizzle. Cancel instead: it keeps the record and gives guests a clear "the host called this off" page if they follow a reminder later.
Recurring events
If the event is part of a series, editing offers to apply detail changes to future occurrences too, and cancelling can end the whole series. See Recurring events.
