The main window of HyperCalendar enables you to set an alarm reminder at the hour you have specified. 

The Diary tab of HyperCalendar is the place where you can insert text and pictures that express your feelings and ideas. 

The Options window allows you to configure system settings, the date format, the start day of the week and the search options. 

This is how the actual calendar looks like, its semitransparent display making it easier for you to visualize the days when you set reminders.
