# Schedule
The "Schedule" section in the Voyage drawer shows a timeline of port calls on a voyage. You can create, rearrange, delete and edit port calls directly from this screen.
## Managing port calls
When hovering the mouse over a port call in the schedule, a toolbar in the upper right will appear.
To insert a port call before or after the port call you are editing, click the **Create New**
button and select **Before** or **After.** A window to create a new port call then opens.
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, click and drag the **Move**
button to move the port call into place.
## Locking voyage start date and ballast port
In the voyage drawer at the schedule section you will find a checkbox for locking the update of voyage start date and ballast port. This checkbox is not visible while the voyage has status Estimate or Unallocated.
