automaticallyAfterDays

The number of days between rotations of the secret. You can use this value to check that your secret meets your compliance guidelines for how often secrets must be rotated. If you use this field to set the rotation schedule, Secrets Manager calculates the next rotation date based on the previous rotation. Manually updating the secret value by calling PutSecretValue or UpdateSecret is considered a valid rotation.

In DescribeSecret and ListSecrets, this value is calculated from the rotation schedule after every successful rotation. In RotateSecret, you can set the rotation schedule in RotationRules with AutomaticallyAfterDays or ScheduleExpression, but not both. To set a rotation schedule in hours, use ScheduleExpression.
