How to edit a calendar event
Update your device to the latest software, and make sure you're using an Apple Intelligence-enabled device with Siri AI turned on. If you need help, learn how to get Siri AI.
Activate Siri, then tell Siri what you want to change within an existing calendar event. For example, you might say, "Move my family video call to tomorrow." If more than one matching event appears, Siri can ask to clarify. Let Siri know which event you want to edit.

Tap Change. If you want to make additional edits, open the Calendar app and tap the event.
