On April 30th, Google Netherlands celebrated Queen’s Day with the above logo.

Queen’s Day is a national holiday in the Netherlands, the Netherlands Antilles, and Aruba on 30 April. Queen’s Day celebrates the birthday of the Queen of the Netherlands and is supposed to be a day of national unity and “togetherness”. […] During the celebrations as reference to the colours of the House of Orange-Nassau, people dress in the colour orange, which is sometimes called “orange craze”. [Wikipedia]

Google had celebrated the holiday previously, in 2003 and 2005 (the logos look pretty much the same though).
