# Schedule
The "Schedule" section in the Voyage drawer shows three different sub-sections:
**Schedule:** a timeline of port calls on a voyage, where the left side shows *ETA* and *ETD* time- and dates, as well as *Days Extra* and *Waiting Days*, and the right side shows the *port calls*, their *reason for calls*, *Port Costs* and *Total Days*. You can *create*, *rearrange*, *delete* and *edit* port calls directly from this screen.
**Edit Schedule:** a list of all the port calls of the voyage, with their respective reason for calls. You can open/close the collapsable items to find the port call's *Port Cost*, *Days L/D,* Fix *and Extra.* You can also find the cargo port's *Quantity, L/D Rate, Rule, Laytime Term, HC Rate, Currency, Measurement* and *HC Lumpsum*. All of these fields are *editable*. The cargo highlighted in **blue** in the Cargo List section will also have its port calls highlighted correspondingly in the Edit Schedule section.
**Routing:** TBA.
### 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 Waiting Days
Within the Schedule section, you will find a checkbox for *locking* the update of *voyage start date* and *Waiting Days*. This checkbox is not visible while the voyage has status **Estimate** or **Unallocated:**
