Which date type can a project manager manually modify?

The planned date type is one that a project manager can manually modify because it typically represents a target date that has been set for the beginning or completion of a project or a project task. This date is established during the planning phase and can be adjusted based on project needs, timelines, and resource availability.

By design, planned dates are flexible, allowing project managers to respond to changes in project scope, resources, or timelines. When a project manager assesses how the project is progressing, they can update the planned dates to reflect realistic expectations, ensuring that all stakeholders have an accurate understanding of the project schedule.

On the other hand, estimated, projected, and actual date types serve different purposes. Estimated dates are generally used for forecasting and are based on assumptions rather than direct modification. Projected dates might adjust based on trends and analysis but are not directly editable in the same way as planned dates. Actual dates are automatically populated in relation to completed tasks and represent the real time that a task or project has taken. Thus, they reflect historical data and cannot be manually changed by project managers.
