The Event calendar web part is used for displaying documents ordered by date in a calendar. Its appearance is similar to the ordinary Calendar web part. You can scroll through months by using the two arrow links in the top left and right corners of the calendar.
The web part can be used for displaying documents of various types, but only one type can be displayed at the same time.
