Milestones Have a 0-Day Duration

A milestone is a special type of action card that represents a key date or checkpoint in your project — for example, a launch date, a review deadline, or the end of a phase.

You can spot milestones in a few ways:

Gantt view — milestones appear as diamond shapes on the timeline

Action card — a flag icon appears on the card

Table view — milestone rows are highlighted in light yellow, and you can show a Milestone column

Tip

To see all milestones across your projects at once, create a milestone summary view from the Views menu.

All milestones now have a 0-day duration. This means a milestone represents a single point in time — it has a due date but no start-to-end range.

Previously, milestones defaulted to a 1-day duration and could be stretched to span multiple days. That is no longer the case. Milestones are strictly 0 days.

Milestones without dependencies

If a milestone stands alone (no dependencies or predecessors), its due date stays the same. The only change is that the duration becomes 0, and any previously set start date is removed.

Milestones with dependencies

If your project uses auto-scheduling (On or Strict) and a milestone has dependencies, some dates on your timeline may shift.

Here's how:

Strict mode schedules everything "as soon as possible." When a milestone's duration drops to 0, it snaps to the earliest available date after its predecessor finishes. Any actions that depend on the milestone then shift earlier too, since the milestone no longer occupies a full day.

When auto-scheduling is set to On, the milestone's due date adjusts for the removed duration, and dependent actions shift accordingly — typically by one day earlier.

If you want to keep your current timeline exactly as it is, you can convert milestones back to regular actions before the change takes effect. This preserves the original duration and dates.

1. Open the milestone action card

2. Click More (the three-dot menu)

3. Select Unmark as milestone

1. Show the Milestone column in your table

2. Double-click the milestone icon on the row you want to change

3. Select Not milestone

Milestones with sub-actions

If a milestone has sub-actions, we recommend removing the milestone flag and converting it to a regular action to avoid unexpected date shifts.

Save a baseline first

If you're concerned about timeline shifts, take a baseline snapshot of your project beforehand. This gives you a reference to compare against. Go to your project settings to create one.

This update aligns Hive's Gantt view with how milestones work in other project management tools. The industry standard is that milestones are zero-duration markers — they represent a point in time, not a span.

This also means you can now set a milestone as dependent on an action and have them share the same date, without needing to adjust predecessor formulas.
