From the Day or Week view, click the "Add Event" button to add an event. Or if you prefer, from the Day view, click on the hour in which your event starts. This will take you to the "Add Event" page, on which you can set:
Event Name: This is a short description of the event, 80 characters or less, that will appear in your calendar. Use the Description field if you need to add more details that don't fit within the 80 characters.
Date: This is the date on which your event appears. If you want the event to appear on multiple days, make it a recurring event.
Time: If the event doesn't have specific hours, select "All Day Event" . All Day events will appear at the top of your day view. For events which happen between set times, choose the "timed event" radio button.
Start Time: Remember to select "AM" or "PM".
Duration: This lets you specify how long the event will last.
Description: This field allows you to enter more detail about an event. It will not appear in the Calendar views but will appear when you click on the event.
Repeat options: These settings allow you to save time by repeating events rather than entering each instance separately.
Reminder: Specify the time and e-mail address to which a reminder should be sent. Reminders can be sent to a group distribution list or to an email pager.
Press any of the "Finished" buttons to save and schedule your event.
