If you are wondering as to why there is a change of Google logo on its homepage today, its because today is the longest day of the year aka Summer Solstice, and the beginning of summer in the Northern Hemisphere.
Today, the sun is directly overhead at noon at the Tropic of Cancer and on the day of Winter Solstice, around 22nd of December, the sun is overhead at noon at the Tropic of Capricorn, which marks the beginning of winter in the Northern Hemisphere.
