# Schedule The *Voyage schedule (Figure 1)* visualization may be found on the right-hand side of a voyage drawer. This section is highly customizable: for example, you can change the voyage start date, lock it, update the port call sequence, and edit port calls by hovering over a port call box.

The *Schedule Timeline* is a fully interactive module. Each port represents a draggable block - if you reorder the blocks with not-fixed port calls *(Figure 2)*, you will update the port call sequence on the opened voyage correspondingly:

Next, each *Port Call* block is clickable, and it brings up a [Port Call](https://docs.dataloy.com/release-8.16/voyage-management-system/step-by-step-guides/port-calls) drawer. The small ovals inside of each *Port Call* block are called chips and include a piece of related information: *Days at Sea + Extra Days at Sea*, *Actual Speed*, and *Distance between Ports*. Every oval is clickable and allows editing corresponding sea passages *(Figure 3)*.

Moreover, the Port Call blocks include a small hover actions toolbar that provides the following actions on the voyage schedule sequence: show Port Cost history overview, create new Port Call to the current schedule, edit the selected Port Call, or delete the Port Call. #### Hover Toolbar When hovering the mouse over a port call in the schedule, a toolbar in the upper right will appear. * [View](https://docs.dataloy.com/release-8.16/voyage-management-system/step-by-step-guides/voyages/maintain-voyages/overview/schedule/find-a-port-call) and [maintain](https://docs.dataloy.com/release-8.16/voyage-management-system/step-by-step-guides/voyages/maintain-voyages/overview/schedule/maintain-port-calls) port costs for the selected port. * To *insert* a port call before or after the port call you are editing, click the **Create** button and select **Before** or **After.** A window to create a new port call then pops up. * To *edit* a port call, click the **Edit** button. * To *delete* a port call, click the **Delete** button. * To *change* the order of port calls, simply *hover over* a port call to move it into place.
