Due Date Types
Tasks support three types of due dates:
Fixed date — a specific calendar date you set manually
Relative to critical date — calculated as X days before or after a linked critical date (updates automatically if the critical date changes)
Relative to another task — calculated as X days before or after a linked task's due date
Using relative due dates is powerful for practice-area workflows — if a hearing date shifts, all tasks linked to it update automatically.
Business days: You can set the offset to count in business days (skipping weekends and England & Wales bank holidays) rather than calendar days.
