By default, all Cohorts are evergreen and will not expire. Access dates may be set up optionally to control the length of time that a Cohort is accessible to learners who are enrolled in it.

You can set start and end dates to your Cohort under Cohort Settings. Open your Cohort and select the three dots (...) at the top of the course Path directly under the name of the Path. This will open a menu with additional options. Select "Configure Cohort" from the menu, then "Configure availability":

Toggle "Limit learner access" ON, then select the calendar icons to pick start and/or end dates for your cohort:

Learners will only be able to access the Cohort between these dates. Save your changes and exit.

If you have multiple cohorts, you will need to adjust the access settings on each cohort. 

When enrolling, learners will see the Cohort start date displayed.

Registered learners will see all content locked prior to the start date.

After the Cohort end date has passed, learners will no longer be able to open the Cohort. Expired Cohort will display to the learner with the message "Access expired." Learners will not receive notifications from expired Cohort.

Note: If you would like for learners to have read-only access to their completed paths, mark the Cohort complete instead of setting an end date to the learners' access.
