Adding New Milestones
- Start with a Microsoft Project plan that contains a few tasks. In this example, our simple project plan contains four tasks, but no milestones yet:

- To insert a milestone in the middle of existing Microsoft Project tasks, select the task below where you want to insert the new milestone. In this example, we want to insert a new milestone between "Task B" and "Task C", so we'll make sure that "Task C" is selected:
- Press the INSERT key on your keyboard:
- You should now have a blank row in Microsoft Project, which will give you space to enter the new milestone:
- Type in the name of the milestone, set the duration to "0 days", and then set the start date of the milestone:
Notice that Microsoft Project automatically sets the finish date and the start date equal to each other. This is because the milestone is zero days in duration.
- Because "Milestone 1" is zero days in duration, it should automatically be marked as milestone in Microsoft Project, but it's always good to double-check. To do this, click on Add New Column and then choose "Milestone" from the dropdown:
- With the "Milestone" field showing, we can now clearly see which lines are marked as milestones in Microsoft Project and which aren't:
In most cases, if you insert a task so that it zero days in duration, Microsoft Project will be smart enough to assume it's a milestone. On the other hand, if you create a one-day task and want it to be considered a milestone, you may need to manually change the "Milestone" flag from "No" to "Yes" to force Microsoft Project to treat it as a milestone, instead of treating it as a task with a very short duration.
