May 27th in the United States is Memorial Day. A Google Doodle Memorial Day message today will play a special bugle call at 3PM local time.
Google traditionally marks Memorial Day in the US with a flag on its homepage and gray version of the company logo. Update 5/30/22: Tapping the logo this year takes you to the “Memorial Day” Search results page with a row of flowers at the bottom. These long-headed poppies (according to Google Lens) move as if there’s a breeze, and are accompanied by “For all who sacrificed, Thank you.” You can replay (or share) after it finishes. Update 5/31/21: The Doodle this year is a gray Google logo (on a dark background in Discover and the mobile Search app). Tapping the American flag on the desktop homepage takes users to a Search results page that features an animation of three waving flags.
