The end date the calendar pulls in the original end date set by the user. The task displays the actual end date, and the original end date is hidden. It is visible if you unmark complete which is not helpful to us.

I would ask that both the original end date and actual end date be visible in the task itself. The business use case is we need to track postmortem both dates to discover why tasks were late or finished early and the impact this has on our project planning.

We ask for the calendar to reflect the actual end date of a task. We are trying to create an enterprise level calendar, and it does not help us to show the original end date that was entered. Especially if it was missed or finished early. Then it appears to not match the end date in the task and causes confusion. To further clarify, we want to see the date it went out (actual end date), not the date that was planned (original end date).
