The event template is used to mark any events. Use it via the Form, or the following template code:

{{Event
 |start_date = YYYY-MM-DD HH:MM
 |end_date   = YYYY-MM-DD HH:MM
 |location   = Comma, Separated List, of Locations
 |organiser  = Organisation Name
}}

Replace the values with your own, of course. The event title is the name of the page on which you place the template.
