The Dates report allows a teacher to edit dates (e.g. due, cut-off, restricted access) for activities (e.g. quiz, assignment) and resources in their topic in one place. This saves time when preparing the topic for teaching.
Note: Not all dates are included in this report (e.g. the Allow posts from forum date) so those dates will need to be adjusted in the activity/resource.
On your topic's home page, click on the Topic Management
Click on the Actions menu cog in the top-right corner, and then the More… link
Click on the Dates link which will either appear under the Topic administration tab or the Reports tab (if Completion tracking is enabled)
You will see the Activity view filter screen
You can filter for specific activities, however, to see all activities leave the filter set to All activities and click the Expand all link (right of the screen)
Change the dates you need to. Note: You can add dates by ticking the Enable box (you will not be able to change dates where there is no Enable box)
