iCal is an elegant personal calendar application that lets you keep track of your appointments and events with multiple calendars featuring at-a-glance views of upcoming activities by day, week or month. iCal lets you create separate color-coded calendars for your home, school and work schedules, and it lets you view all your different calendars at the same time from within a single unified window. You can use iCal to remind you of time commitments, keep track of your deadlines, send and receive email and text-message notifications, set alarms, and even create and prioritize To Do lists.   [edit]
