Go to Dates -> Sheduler settings to customize day scheduler:

Scheduler settings allow to:

• set default holidays. Select/deselect any weekday. Checked days will be marked as holidays in the calendar. Default holidays are Saturday and Sunday, but you can change this if needed.
• select size and color of scheduler lines. Select line size in the drop-down menu. Available sizes of scheduler lines are 5, 10, 15, 20, 30 and 60 minutes. Choose the color of lines. Click color box to open the color picker window. You can select two different colors – for in-office time and for out-of-office time. In-office time will be set in the Business day box. Other time is accepted as out-of-office time.
• choose a mark for the dates with notes. That is the way how dates with notes will look in the desktop calendar. The possible marks are listed in the drop-down menu. They are: left or right top corner in red color or in date color and underlining the date.
• indicate time when your business day starts and ends.
• select Show description in hint and Show attachments small icons. The first option means that event description will be shown together with its subject in hint for the small calendar. The second option changes the size of attachments icons which are displayed in the record editor window.

For Screen Calendar Outlook Edition: you schedule in Microsoft Outlook Calendar. Please check Outlook options for scheduler settings.
