Constraints

Example
“We want to launch this by Friday so please complete this on staging by Wednesday. The client has one hour left in their budget so let’s try to spend at most 30 minutes on this.”
Mandatory?

We use the Time Constraints field to lay out a full picture of what the calendar requirements are for the delivery of this task.

Note that this is distinct from the task due date. The due date is when the current task assignee needs to complete their part by, while the Time Constraints field should have a more holistic picture.
