You can set new announcements to post at a certain date and time. The delayed post information also displays directly in the Announcements page. Delayed announcements are not displayed to students until the intended date and time.

Notes:

• If you create an announcement in an unpublished course, the delay posting date must take place after the course has been published for notifications to send to those who have chosen to receive notifications for new announcements.
• If an announcement is scheduled to post before the course start date and the Students can only participate in the course between these dates setting is enabled, students will not receive announcement notifications.
• If you check the Delay Posting checkbox and don't set a date the announcement will post immediately.
• Your course must be published for students to receive announcement notifications. Students do not receive new announcement notifications for announcements imported from another Canvas course.
