You can set the START and END date of an automatic response collection. 

You can set the date of an automatic START and the END of your response collection. You need not worry about the exact moment when you need to stop your surveys manually.

1. Open your Dashboard page with all your projects (My Surveys).

2. Pick your survey and click on the Settings link in the main menu.

3. Activate the Survey deadlines switch and enter the date in the End field. This will be the date when the survey automatically DEACTIVATES itself, and will not be collecting answers any more.

The survey can be reactivated at any time. Just switch OFF any Survey deadlines or, move the end date to a later date.

Tip: A survey with automatic deactivation of response collection will collect answers until midnight of the same day. The next day, at 00:01sec, It will be deactivated and will not collect any responses.

Warning: If the survey stops collecting answers and you decide that you wish for it to continue, make sure that you have not set an automatic end. This is usually the most common issue with sudden termination of data collection. People tend to forget that they have set something and do not realize that they want to collect data longer than originally planned.
