Google Doodle welcomes the first day of spring

Today Google dedicates a special animated doodle to celebrate a celestial event, The Spring Equinox, which denotes the beginning of spring.

The first day of the season is known as the spring equinox, which generally falls on Thursday. During this time, the day and night are in equal length.  Equinox is regarded as the instant of the time when Earth’s equator passes through the center of the sun, making it visible directly above it. This rare phenomena occurs two times in a year, once on March 20th and the other on September 23rd. On this special day, the sun rises in the east and sets in the west.      -Akhila kakarala
