## Time Window for Each Run Day Pane Overview

A time window is the period of time during which a task can begin on any scheduled run day. By default, a task can start any time between 00:00:00 and 23:59:59 on a run day. For example, if you schedule a task to run every Monday using the default time window, the task can start at or anytime after midnight early Monday morning. It cannot, however, start after 23:59:59 Monday night.

Note The time window does not extend beyond 24 hours, or more specifically, beyond 23 hours, 59 minutes, and 59 seconds. For example, you can not set a time window starting at 03:00:00 and ending at 05:00:00 the following day.

You can control when a task runs by changing the start and end times of its time window. A time window can extend past midnight.
