Never Miss a Milestone: Auto-Sync Project Dates to Calendar
Update a project milestone date in Linear, and it instantly appears on your calendar. Milestones stay visible across your entire workflow.
Trigger
Project Properties Updated
Fires when properties on a Linear project change (status, lead, target date, priority, etc.). Covers projects in both public and private teams — polls with the connected user's token.
Action
Create Event
Creates an event on a google calendar, needing rfc3339 utc start/end times (end after start) and write access to the calendar. by default, adds the organizer as an attendee unless exclude organizer is set to true.
Why this helps
Project milestones live in Linear but don't surface on your calendar until late, leaving teams scrambling at the last minute instead of planning ahead.
- Gives milestones calendar visibility so they guide your weekly planning
- Prevents last-minute scrambles by surfacing milestones early
- Centralizes project timeline visibility in your calendar
- Enables better cross-team coordination on deadlines

Questions about this workflow
Should milestone events be all-day or specific times?
By default, they're all-day events. You can customize: 'Create all-day milestone events' or 'Set milestone reminders for 9am'.
What if a milestone date changes multiple times?
Notis updates the existing calendar event, so no duplicates pile up. Your calendar stays accurate with each date change.
Can I include only specific projects?
Yes. Add filters to your prompt: 'Only for projects in the Product team' or 'Skip archived projects'.
