When is Google I/O Developer Conference Start?

Next estimated start date: Tuesday, May 18, 2027.

The next Google I/O Developer Conference is estimated to start on May 18, 2027. Google has not announced the official 2027 dates. The estimate follows the recent third-Tuesday schedule: Google I/O began on May 20 in 2025 and May 19 in 2026. Only the estimated opening date is listed until Google publishes its next save-the-date announcement.

Google I/O 2027 Date Status

Google has not yet confirmed the start date, end date, keynote times or registration arrangements for Google I/O 2027. May 18 is the third Tuesday of May 2027 and matches the opening pattern used for the two most recent conferences.

The estimate should not be treated as a confirmed booking date. Google announced its 2025 conference on February 11, 2025, and announced the 2026 conference on February 17, 2026. A similar announcement window would place the first official 2027 details in early 2027, although Google is not required to follow that schedule.

Could the date change?

Yes. Google I/O has no permanent calendar rule. The conference is usually held in May, but its exact week, duration and format may change. The shortcode will need to be updated when Google publishes the official 2027 date.

Expected Google I/O 2027 Location

The 2027 venue has not been announced. Google held its 2026 conference at Shoreline Amphitheatre in Mountain View, California, with online access through the official Google I/O website. Earlier editions have also used Shoreline Amphitheatre, but this does not confirm that Google will return to the same venue in 2027.

Anyone planning to attend in person should wait for Google to confirm the location before arranging flights or accommodation. Access to the physical event may be limited even when the online program is open to a wider audience.

When Will the Google I/O 2027 Program Be Released?

The session schedule is normally published after the initial date announcement. The 2027 program is expected to identify the opening keynote time, developer keynote time, livestream schedule and any sessions released separately for on-demand viewing.

For Google I/O 2026, the official livestream schedule placed the Google keynote at 10:00 a.m. Pacific Time on the first day and the Developer keynote at 1:30 p.m. Pacific Time. Live sessions continued across two days, followed by additional sessions and codelabs released online. These times describe the 2026 event only and should not be used as the confirmed 2027 schedule.

What usually opens Google I/O?

The main Google keynote normally opens the public conference program. It is used for company-wide product announcements and demonstrations. A separate Developer keynote focuses more closely on tools, platforms and services used by software developers.

Session categories vary each year. Recent programs have included material related to Gemini, Android, Chrome, Google Cloud, web development and developer tools. The official 2027 topics will not be known until Google publishes the program.

Google I/O 2027 Registration and Tickets

Registration for Google I/O 2027 is not open. Google will publish the attendance rules, eligibility details and registration process on its event website after the conference is announced.

Online registration and in-person attendance should be treated separately. Registering for digital updates or livestream access does not necessarily provide entry to the physical venue. When registration opens, check whether the confirmation refers to online participation, an in-person invitation or another event format.

Where will registration be announced?

The primary registration page is expected to appear on io.google. Date announcements may also be published through the Google technology and developer news section and the Google Developers Blog.

Third-party conference listings can be useful for reminders, but registration details should be checked against a Google-owned page before any travel or payment decision.

How to Watch Google I/O 2027

Google has not released viewing links for the 2027 conference. Based on recent editions, the Google keynote and Developer keynote are likely to be streamed through the Google I/O website and Google’s official YouTube channels. This remains unconfirmed until the next event page is published.

The Google I/O 2026 archive currently provides keynote recordings and on-demand technical sessions. That archive can be used to catch up on the previous conference while waiting for the 2027 schedule.

Will recordings be available after the event?

Google has provided keynote recordings, sessions, workshops and other technical material on demand after recent I/O conferences. The availability and release timing of 2027 recordings will be confirmed with the official program.

Google I/O 2027 Time Zone Information

Live keynote times are generally announced in Pacific Time because the event has recently been hosted in Mountain View, California. Viewers outside the United States should convert the published time using the date-specific Pacific offset.

California observes Pacific Daylight Time during May. Under the current time-zone rules, a 10:00 a.m. opening keynote in Mountain View would begin at 1:00 p.m. in New York, 6:00 p.m. in London and 8:00 p.m. in Türkiye. These examples are not the confirmed 2027 broadcast time.
