With the Assignment Deadlines Pro plugin, extending assignment deadlines is simple and flexible—especially for manually set due dates. This feature is useful when students need extra time due to special circumstances or delays.

To extend a manual deadline:

• Go to your LearnDash course and open the Assignment Uploads section.
• Click on Assignment Settings for the relevant assignment.
• Make sure Manual Deadline is selected as the deadline type.
• In the Extend Deadline field, add the number of hours or days you want to extend.
  Save your changes.

That’s it! The new extended deadline will apply immediately, giving students additional time without disrupting others.
