# Manage duration of an intercept study

An intercept study can run for up to 90 days. However, you can customize the length if you want yours to end sooner.

{% hint style="info" %}
**Note:** Keep in mind that depending on your desired sample size, the specificity of your intercept URL, and any targeting attributes you’ve applied, you may benefit from a longer study duration to get the information you need.
{% endhint %}

{% stepper %}
{% step %}
Navigate to the **Overview** tab of your study.

![](/files/15e2d03811db412150359181ecdb48bd4fd6c5fe)
{% endstep %}

{% step %}
Click anywhere in the **Mission details** section.
{% endstep %}

{% step %}
In the **Ends after** field, enter the number of days you want your study to be open.

![](/files/7ca0647a5b9ec6adebd4d0f00260b67525878cd5)

{% hint style="info" %}
**Note:** Your study duration must be at least 1 day and may not be more than 90 days.
{% endhint %}
{% endstep %}

{% step %}
Click **Done**.
{% endstep %}
{% endstepper %}

Now, your study duration is saved. Once you launch your study, it will automatically close after the number of days you’ve selected.

{% hint style="info" %}
**Note:** Your study will automatically close if you hit your designated participant limit, even if that occurs before your set study duration. Additionally, if you want to close your study early, you can do so manually. For more information, see [Close an intercept study](/intercept-studies/manage-an-intercept-study/close-an-intercept-study.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.dscout.com/intercept-studies/create-an-intercept-study/manage-duration-of-an-intercept-study.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
