# Change expiration

> Extend or shorten how long participants have to respond, for future runs or for runs you already sent.

The expiration sets how long participants have to respond to each run. The countdown starts at the run's scheduled send time. When the expiration passes, the run closes.

## Who can change expiration

Owners with edit access can change the expiration after launch. You can change it on an active, paused, or completed pulse. You cannot change it on an archived pulse.

## Change the expiration

<Steps>
  <Step title="Open the Expiration setting">
    Open the pulse and select the **Settings** tab. Select edit on **Expiration**.
  </Step>

  <Step title="Choose a new duration">
    In **Edit expiration**, choose a duration in **Expire after**. The shortest option is 1 hour. You can also choose **No expiration**.
  </Step>

  <Step title="Choose runs to update (optional)">
    To change runs you already sent, select **Choose existing runs to update**, then select **Next**. In **Select runs**, select the runs to update. Switch between **Current runs** and **All runs** to include closed runs. You can also choose specific responses in a run.
  </Step>

  <Step title="Review the change">
    Select **Review changes**. **Review expiration change** shows the old and new default expiration, and the runs and responses you selected.
  </Step>

  <Step title="Save">
    Select **Update expiration**.
  </Step>
</Steps>

## What changes

* **Future runs:** The new duration becomes the default expiration for all later runs.
* **Existing runs:** If you do not select runs, existing responses keep their current expiration.
* **Selected runs:** The new expiration applies to the runs and responses you selected. The new deadline cannot be in the past. If it is, choose a longer duration or **No expiration**.

### Reopen a closed run

If you extend a run that already closed, the run opens again with the new deadline.

If the pulse is a completed one-time pulse, it becomes active again. A paused pulse stays paused.

### Participant notice

Respondents who have not submitted get a Slack message about the new deadline. Windy sends it 5 minutes after your last change, so several quick edits send only one message.

## Other places that set expiration

**Send again** and **Edit schedule** also set the default expiration for later runs. To change runs you already sent, use **Edit expiration**. See [Send again, pause, and resume](/features/pulse-surveys/send-again-pause-and-resume) and [Expiration and deadlines](/features/pulse-surveys/expiration-and-deadlines).
