Understand How Microsoft Project Milestones are Calculated

A Milestone normally has a zero duration and is used to mark the start or finish of a major event. A Milestone is a Start Milestone when it has no predecessors and is scheduled at the start of a work day, and a Finish Milestone when it has no predecessors and is scheduled at the end of a work day.

Other products allow the user to choose if a Milestone is a Start or Finish Milestone but Microsoft Project does allow this option.

Milestones ignore their assigned calendar and are always scheduled at the same date and time of their driving predecessor irrespective of the calendar that the milestone is assigned. When a predecessor is assigned lag, then the lag acknowledges the Milestone calendar and the Milestone start date and time will be within the Milestone calendar.

Microsoft Project Milestones calculate like Oracle Primavera P6 Finish Milestones but are imported from Microsoft Project into Oracle Primavera P6 as Start Milestones.
