# Set your business hours
Keeping uses your organization's business hours to calculate your agents' response time. Your business hours will also reflect what times are shown on the [Busiest Times chart](/help/reporting-and-analytics/advanced-reports/team-performance.md) in Advanced Reporting.
Business hours may also be used to determine which auto reply is sent. See [Configure Auto Replies by Business Hours](https://docs.keeping.com/help/fundamentals/enable-an-autoreply#configure-auto-replies-by-business-hours) for more information.
See below on how to configure a per mailbox time zone.
{% hint style="info" %}
If you would like configure business hours where you are "always open", then choose 00:00 to 23:59, and select the **Open** checkbox for every day.
{% endhint %}
Set your business hours and timezone in the **Organization** tab of your **Keeping Settings**.

### Set a time zone per mailbox
If your team operates in multiple regions, you can override the organization time zone on a per-mailbox basis. This is helpful when, for example, your `support@` inbox is staffed in New York but your `eu-support@` inbox is staffed in London — response times, SLA timers, and business hours calculations will then reflect each mailbox's local time.
To set it:
1. Go to **Settings → Mailboxes** and click the mailbox you want to edit.
2. Scroll to the **Mailbox Time Zone** field.
3. Pick a specific time zone, or leave it set to **"Use organization time zone"** to inherit the default.
The same business hours schedule from your organization settings applies; only the time zone in which those hours are interpreted changes per mailbox.

## 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://docs.keeping.com/help/preferences/set-your-business-hours.md?ask=&goal=
```
`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.
