MODIFIED ALERTS FOR OFF HOUR CALENDAR EVENTS

A modified alert triggering system modifies alerts associated with calendar events. The system identifies a user’s normal calendar hours. Further, the system determines that a calendar event is scheduled outside of user’s normal calendar hours. Based on determining that the calendar event is scheduled outside of user’s normal calendar hours, the system modifies an alert for the calendar event. For example, the modified alert can be louder than a normal alert, the modified alert can be a different alert tone than the normal alert tone, etc. The system then triggers the modified alert for the calendar event
