Excellent - clean, flexible, powerful.

Pros
— Clean, simple, highly legible interface
— Ability to track multiple events
— Ability to use date or date/time as needed
— Notifications Integration
— Seemless integration with my iOS devices.

Suggestion
— Would love the icon to have a badge with the days to the next event.

Summary - Does just what I need, and well worth the $0.99 to unlock the unlimited date range functionality.
