# Schedule Restrictions
Schedule Restrictions lets administrators prohibit DQ Jobs from running on certain days or during specific time frames. Limiting job scheduling to certain days can be especially helpful for ensuring the freshness of data and reducing operational costs when running jobs during off-peak times. If a user attempts to schedule a job during a restricted time period, an error message displays preventing the user from scheduling.
{% hint style="info" %}
All times on the Schedule Restrictions page reflect the UTC timezone.
{% endhint %}
In Standalone deployments of Collibra DQ, you can enable the Job Scheduler by setting the environment variable `SCHEDULE_ENABLED=TRUE` in the **owl-env.sh** file. This is enabled out-of-the-box, so if you need to turn the Job Scheduler off, you can set the value to `FALSE` instead.
In Cloud Native deployments of Collibra DQ, the **Web ConfigMap** contains the `SCHEDULE_ENABLED=true` variable.
