# Setup schedule

> Control when a campaign starts and what hours it's allowed to call.

Control when a campaign begins and what hours it's allowed to place calls.

## One-time start

Set a `scheduled_start_time` and timezone to have the campaign start automatically at a specific date and time, instead of starting it manually.

## Recurring working hours

Set working hours and a timezone to restrict the campaign to a recurring daily calling window.

<Note>
  A campaign automatically pauses outside its configured working hours and resumes at the start of the next window — if a campaign looks stalled, check whether it's simply outside its working hours before assuming something is wrong.
