To create an event, just as you would create any other type of content, click on the 'create content' pane of the control panel, then click 'event'. Now, set the start and end times of your event and enter a title and the body of the event, then click 'submit'.

If you have the events block displayed on you site, notice how the calendar now shows the date of your event highlighted.

Click on the name of the month to begin browsing the calendar and you will see your event.

Browsing an online calendar in this way is a very nice way for members or general visitors of your site to find out what your group or organisation is up to.
