To stop “Time to Leave” alerts on iPhone, open Settings > Apps > Calendar > Default Alert Times (older iOS: Settings > Calendar > Default Alert Times) and turn off Time to Leave. Calendar then stops adding travel-time alerts based on your location and traffic. You can still set normal alerts for each event.
Quick Answer
Settings > Apps > Calendar > Default Alert Times > Time to Leave off.
Steps to Turn Off Time to Leave
- Open Settings.
- Tap Apps > Calendar (on iOS 17 and earlier, just Calendar).
- Tap Default Alert Times.
- Turn off Time to Leave.
Change Alerts for One Event
- Open the event in Calendar and tap Edit.
- Tap Alert and choose a fixed time or None.
- Remove the Location or turn off Travel Time if you don’t want travel estimates.
Alert Options
| Setting | What it does |

- Want fewer notifications overall? See managing notification settings.
- Other camera and system settings: See the QR scanner setting.
