Calendar alerts are, by default, set to alert you a day before the event occurs. But this can be changed and if you sync multiple calendars, it can get changed. Apparently, this can lead to issues like the calendar alerts not working at all.

While there are multiple narratives to this, we’ll look into fixing calendar alerts the way you it’s usually intended. For starters, this is the theme: I want to set up Calendar alerts the way I want. Thankfully, iOS lets you do that. Here’s how.

How to Manage Calendar Alerts on iPhone in iOS 7

Setting up Calendar Alerts for Events/Birthdays etc:

Set up Calendar Alerts for Events and Birthdays on iPhone in iOS 7

  • Open the Settings app
  • Scroll down and tap on Mail, Contacts, Calendars
  • Scroll down. Under Calendars, you should see Default Alert Times. Tap on this.
  • You can now tap on each of the options (Birthdays, Events, All-Day Events) to set a specific alert time for these.

Typical Alert Times:

  • For Birthdays, you’d typically want a 1 day before (9.00AM) alert if you plan meticulously or a On day of event alert if you plan on the day.
  • For Events that are time-specific, you’d want a 30-minute-prior (or lesser) alert.
  • For All-Day Events, you obviously need just an on-the-day alert.

But of course, all this is just relative. You can set any specific alert time as per your preference.

Now all this is for individual events that you have on your calendar. Do these work on all calendars that you sync? Yes, irrespective of what account you sync from. Gmail, Exchange, iCloud etc. However, note that if you run into alert issues, you might want to check the event properties from the Calendar app itself. Suppose an event has an alert set to none within its preferences, you will not get an alert.

Calendar Alerts for Shared Events

When an event is created in a shared calendar, the alert for this event is set by the person who created the event. This depends on the default setting that their iPhone/Calendar app has. You will receive an alert based on this alert type.

However, if you do want to make sure you get alerts of new, modified or deleted events, you should make sure you turn on the toggle for Shared Calendar Alerts as shown above.

    Wondering why setting individual alerts for each event didn’t work when default was none? Switched default to 15 minutes just to have something there. It works at 15. Testing for additional alert of 5.
