Events showing at the wrong time?
- Everything is off by the same number of hours: your primary time zone, or your device's time zone, is wrong.
- Only one event is off: it was created with its own time zone. Open it and check the time zone next to the time.
- Different on your phone and computer: the app follows the phone's time zone while the website follows your primary time zone. Make them match.
