What is a Milestone?
A Milestone marks a key moment or event in your Timeline.
Unlike regular Timeline Items, Milestones have no duration — they represent a single day.
When you set an item’s duration to 0 days, it automatically becomes a Milestone.
How to Create a Milestone
1) Changing Duration
- Set the Duration to 0 — it will convert to a Milestone
2) Right-Click to Convert
- Select Convert to Milestone from the menu
