With a business account, you can schedule Pins for future posting on desktop or iOS. You can schedule Pins up to two weeks in advance in your current time zone. Though you can only schedule one Pin at a time, you can have up to 30 Pins scheduled for the future.
Note: Once your Pins are scheduled, you're still able to make updates, like choosing to publish the Pin immediately or deleting it. View your scheduled Pins by going to your profile and selecting the Pins tab.
