One way of promoting greater inclusion of all staff and students is by acknowledging the significant days, festivals or other events not already recognised, for example, by an Australian or state holiday. An edited selection of these days is provided below. More comprehensive diversity calendars are also available for free. For example, the Australian Department of Social Services lists the days celebrated by Australia's major ethnic and religious communities. The United Nations also provides a list of the days, weeks, years, and decades that they observe, each with a designated theme or topic.
