How to Set Default Alert Times for the iPhone Calendar

The Calendar app on your iPhone is a great way to manage your schedule. Adding an event is a short process through the app, and can even be done with Siri’s assistance.

But a crucial element of a calendar system for many phone users is the alert that you receive before a scheduled event is about to occur. While you can manually set an alert time as you create an event, it’s very easy to forget to do. Unfortunately, depending on the current default alert time, this can even mean that you aren’t going to see an alert at all. Fortunately the default alert time is a setting that you can pick, thereby ensuring that any future events you create will send you an alert at your chosen time before that event.
