Events have a title, date and time, description and one or more configurable categories. Past events can be automatically removed from your site.
Default display modes include a calendar, a monthly listing, as well as a custom function to search and filter events to display them however needed. Display is handled via templates (defaults are supplied, which you can copy and edit to make your own) and CSS. So the look and feel is very flexible.
Full Documention for the Events app can be found on our support site.
The example pages make use of Quill so you should download that also if you want to make use of the examples.
