What Is a Change Calendar?
A change calendar is a coordinated schedule recording when changes, maintenance, and releases are planned or prohibited across teams. It marks freeze windows, blackout dates, and approved deployment slots in one place. Pipelines or reviewers can consult it to confirm a change is permitted at a given time.
Why it matters
A shared calendar prevents conflicting or ill-timed deploys, such as shipping during another team maintenance. It makes freeze windows and coordination visible rather than tribal knowledge.
