Google on Saturday celebrated the onset of spring in the northern hemisphere with an animated graphic. March 20 marks the vernal equinox, which is celebrated as the start of the spring season.
In the southern hemisphere, the day is seen as the autumnal equinox, marking the advent of autumn. The tech giant has also introduced a similar doodle marking autumn in the southern hemisphere.
During the spring equinox, the sun moves from the southern to the northern hemisphere while passing the equator. On this day, both day and night have roughly the same length, that is, 12 hours each.
The sun rises directly in the east and sets directly in the west. Post the spring equinox, days tend to be longer than nights.
Spring in the northern hemisphere starts on March 20 every year and ends on June 21, which marks the summer solstice. The season is associated with the earth recovering from the harsh winters, bringing back flora and fauna in full glory.
Welcoming the new season, the Google Doodle today showed a hedgehog with flowers of different colours and leaves on its back instead of its spines. A hedgehog hibernates in the winters and wakes up in spring.
Red and blue flowers complete the word Google. One can also see honeybees buzzing around. This doodle is active only in the northern hemisphere.
The doodle for the southern hemisphere, Google has used the hedgehog with brown leaves, giving an impression of autumn. Here, the hedgehog seems to be gearing up for hibernation, which helps it to survive the harshness of winters.
The second equinox of the year, which marks the advent of autumn in the northern hemisphere and spring in the southern hemisphere, takes place on September 22-23 of every year.
