Automate GitHub + Google Calendar with GAIA

Schedule sprint reviews from milestones and track PR deadlines in Calendar

Engineering teams manage their schedules in Google Calendar and their code in GitHub, but the two rarely inform each other. A milestone due date set in GitHub has no corresponding calendar block. A sprint review meeting gets scheduled without checking when the milestone actually lands. Developers have no calendar reminders for PRs that need attention before a release, and project managers schedule planning meetings without visibility into the current state of the backlog.

GAIA bridges GitHub and Google Calendar so your development timeline and your schedule stay synchronized. Milestone due dates automatically create calendar events with the list of open issues. PR review requests can generate calendar blocks so reviewers have protected time for code review. When a milestone shifts, GAIA can update the corresponding calendar event so the team's schedule reflects the new reality.

This integration is particularly valuable for engineering managers and tech leads who are responsible for both code quality and on-time delivery. Instead of maintaining a project timeline in both GitHub and Calendar manually, GAIA keeps the two in sync so your calendar always reflects what is actually happening in the codebase.

5 things you can automate

Everything GAIA can do when GitHub and Google Calendar are connected.

1

Auto-create calendar events from GitHub milestones

When a GitHub milestone is created or updated, GAIA creates a corresponding Google Calendar event on the due date, including the milestone title, a summary of open issues, and a link to the GitHub milestone page for quick reference.

2

Schedule sprint review meetings from milestone completion

GAIA monitors GitHub milestones and automatically creates a sprint review calendar invitation for the team when a milestone approaches completion, including an agenda pre-populated with merged PRs and any remaining open issues.

3

Add PR review deadlines as calendar reminders

When you are requested to review a pull request on a time-sensitive branch, GAIA adds a calendar reminder so you have a dedicated review slot before the PR's target merge date, preventing last-minute bottlenecks.

4

Block calendar time for on-call from GitHub schedules

GAIA can read on-call rotation schedules defined in GitHub repository wikis or files and create corresponding Google Calendar events so engineers always know when they are on-call without checking a separate document.

5

Update calendar events when milestone dates shift

When a GitHub milestone due date is edited, GAIA automatically updates the corresponding Google Calendar event to reflect the new date and sends update notifications to all invited attendees so the team is always working from accurate dates.

How to set it up

Connect GitHub and Google Calendar to GAIA in three steps.

  1. 1

    Connect GitHub and Google Calendar to GAIA

    Link your GitHub organization and Google Calendar account in GAIA's integration settings using OAuth. Select which repositories to monitor for milestones and which Google Calendar should receive the generated events.

  2. 2

    Configure your scheduling preferences

    Tell GAIA how far in advance to create calendar events, which team members to invite to milestone reviews, how to handle time zone differences, and whether to create individual events or add milestone dates to a shared team calendar.

  3. 3

    GAIA keeps your schedule and codebase aligned

    GAIA continuously monitors GitHub milestone changes and PR activity, updating Google Calendar events in real time. Your engineering schedule stays accurate without any manual calendar management from the team.

Frequently Asked Questions

Yes. GAIA can be configured to add milestone events and sprint reviews to a shared Google Calendar that the entire engineering team subscribes to, making it easy for everyone to see the development timeline without individual calendar management.

GAIA can be configured to automatically delete or mark the corresponding calendar event as cancelled when a milestone is deleted, and to notify invited attendees of the cancellation. You can also choose to keep the event and have GAIA add a note about the deletion.

GAIA primarily syncs GitHub milestones with Google Calendar. GitHub Projects v2 roadmap dates can also be used as a source for calendar events depending on your configuration, but milestone-based sync is the most reliable and fully supported path.
