I want to have an alert 90 minutes before a calendar event. That isn't an option in Calendar on iOS. Fantistical has more alert time options than Calendar so I imagine there's a way to set an arbitrary alert time. Is there a way to do that from the command line or a script?


If you go into the Calendar app you can setup a custom alert per entry. Here I've added an item to my Calendar and then double clicked on it to open up a dialog to customize. Under that menu is an alert section under the time/date area of the calendar entry, in that menu select customize.

You can setup either an email or an audible sound for your specific time


CLI access to Calendar

You could use icalBuddy which was recommended in this other AD Q&A titled: Displaying calendar events as text, in the terminal.


  • I was hoping to do it in iOS, but I did mention the command line so a macOS solution is perfectly valid. I just hadn't looked on my iMac yet. – SSteve Apr 19 at 16:01
