Week Ahead shows the next 7 days of all day events, appointments and reminders in one list that lets you easily see just how much you have on.

Heres an example with 3 hours/2 meetings, 1 all day event, and one reminder due, you can select anything in the list.

• Date - will take you to that day in the Calendar
• All day event/appointment - will take you to that events entry in the Calendar
• Reminder - will show a preview of the Reminder

Theres some commented parts at the top where you can set which Reminder Lists, or Calendars you want to include or exclude from being displayed.

Will also work from the widget but the information preview isn't as rich.
