Date precision

Expected single-date signal; useful for monitoring, but not strong enough for irreversible plans.

Schema posture

Precise Event startDate schema is withheld so the page does not overstate an expected or windowed date.

This is an expected date. Use reminders and monitoring, but verify the source before making travel, purchase, publication, or staffing decisions.

Primary citation

The current date signal points to build.microsoft.com. The source URL is shown visibly on the page so readers can verify late changes instead of relying only on the timer.

Freshness and review

Source policy was reviewed on 2026-04-30. Live countdown values are render-time snapshots; editorial source fields update when the tracked event dataset changes.

Operational detail

The record includes a source-local time and timezone, so city conversion pages can show a real local start time.

Weak-date handling

The page stays crawlable and useful, but confidence copy and schema posture are deliberately weaker than a confirmed event page.

What this countdown tracks

The clock above counts down to Microsoft Build 2027 from Tuesday, May 18 to Thursday, May 20, 2027, Microsoft's flagship developer conference, expected to run as a hybrid in-person and digital event in the Seattle or San Francisco Bay Area.

About this event

Microsoft Build is the company's annual developer conference and the second-most-watched dev keynote on the calendar after Apple WWDC. Founded in 2011 as the successor to PDC and MIX, Build is the venue where Microsoft sets the developer narrative for Azure, Copilot, GitHub, Visual Studio, .NET, Power Platform, Windows, and the broader Microsoft AI Platform. The event combines a Satya Nadella opening keynote and a Kevin Scott / Scott Guthrie technical keynote with three days of breakouts, demos, certifications, and partner sessions.

Build 2027 lands in a year of significant AI and platform expansion: by early 2027, Microsoft's Azure AI Foundry, Copilot Studio, the GitHub Copilot agent, and the Windows AI Foundry runtime introduced at Build 2025 will be in their second or third generation. Build 2026 was held at Fort Mason in San Francisco with a 2,500-attendee in-person cap; the 2027 venue is to be confirmed by Microsoft, with rotation between SF and Seattle expected to continue.

What to expect

Per Microsoft's stated cadence, expect Satya Nadella's opening keynote to anchor announcements across Azure infrastructure, Copilot platform expansions, GitHub Copilot agent updates, Microsoft Fabric and the data platform, .NET 11 (timed to Build 2027 if the cadence holds), and Windows AI APIs. Anticipated themes include continued investment in AI-agent orchestration, deeper Anthropic, OpenAI, and Mistral integration in Azure AI Foundry, expanded support for the Model Context Protocol (which Microsoft adopted across Copilot in 2025), and developer-tooling launches in VS Code, GitHub, and Visual Studio. Per organizer practice, expect 600+ breakout sessions, hands-on labs, and a developer expo across the venue.
