The QuickAdd dialog makes it easy to quickly create an appointment. On your calendar, you select a start time, double-click or drag through the time and the QuickAdd Appointment dialog opens.
QuickAdd is an option. If you would prefer to always open the Appointment page when you double-click or drag on the calendar, disable this feature from your Calendar Preferences.
Select the Calendar for the appointment. Click the time for the appointment or click and drag from the start time to the end time for the appointment. The QuickAdd Appointment dialog appears.
Note: To create an all-day appointment, from the Day or Week view, at the top of the calendar, click and drag over one or more days.
Enter the subject, location, and if this is a repeat appointment, select a repeat mode.
Set the reminder notice for when to be reminded of the meeting start time.
Click OK. The appointment displays on the calendar.
If you need to invite attendees or change repeat options, click More Details to open the Appointment page.
