Siri is magical and fun when it works…
If you’re on the go or just want an easier way to add events to your Calendar app, Siri will happily get the job done for you. Creating an event is super simple and only takes a few seconds.
- Hold down the Home button to activate Siri.
- Tell Siri what you’d like her to schedule. For example: “Schedule a conference call with Phil tomorrow at 9AM.”
- Wait for Siri to show you the Calendar widget and ask for confirmation.
If there’s any ambiguity about what you said, or Siri is uncertain, it will ask you to clarify. For example, if you ask to set up an appointment “tomorrow”, and it’s near midnight, Siri will ask you to specify the date to make sure the appointment is set up properly.
