# Schedule List / Schedule Book

Schedules are used to limit when a policy is in effect, and to set traffic control policies. Configurable as separate objects, schedules can be set on either a recurring or one-time basis and associated with any number of policies.

## Viewing the Schedule Book

This table lists every schedule configured on the security device and contains the following information on each one:.

Name: Indicates the name of the schedule.

Mode: Indicates the mode of the schedule—whether it is recurring or a one-time event.

Comment: This field is optional and may or may not contain any information.

Configure: Click Edit to modify the entry, or click Remove to delete it.

Note: You cannot remove a schedule if it is referenced by a policy. You must first remove it from the policy.
