Calendar
The 'Calendar' can display site, course, group, user and category events in addition to assignment and quiz deadlines, chat times and other course events. Note the colour coding on the screenshot below.
Top tip: A 'Calendar' can be included on a SOL page by adding a 'Calendar' block or 'Upcoming Events' block.
