Best Calendar I ever had

Since 2010 I use the various versions of MiCal and it still provides the overview to me I need for a single day.
Not to mention the silent update of all my other calendars within a minute, the ability to use colors for a fast overview, the ability to insert comments into the appointments, etc.
Unfortunately, I experienced MiCal got frozen several times the last months. Its only a minor issue against all advantages but thats why I only provided 4 stars.
