AgendaX comes with a customizable stylesheet. It is very easy to change background colors, date layouts, ruler colors, etc., and add your own logo and background images if needed through the web-based administration interface of AgendaX.
You can also specify how meetings are displayed: For example, show only weekdays (without Saturday / Sunday), show only meetings within the specified working hours, hide meetings that are marked as free, show the organizer and participants in a tooltip, and so on.
Furthermore, thanks to access to the source code of all views, you can program your own custom views or let us program them for you.
