Spring Equinox or the Vernal Equinox is a signal that Northern Hemisphere of Earth is tilting towards the Sun. Thus, causing longer days and shorter nights. This equinox extends to USA, Central America, Canada, Europe, Asia and northern Africa. India celebrates ‘Holi’ to mark this day and the season. The Southern Hemisphere will experience the fall season.

The day is referred to as fall or autumnal equinox in the Southern hemisphere and Google has a separate doodle for that as well called the Fall 2019 (Southern Hemisphere).

The Google doodle marks the start of Spring season with an image that shows a flower blooming on the Earth and portrays the sunlight falling on it. The doodle, according to Google, has its reach spanning the North and South America, several parts of Europe, Russia, India and few other Southeast Asian countries. In rest of the world, Google showed the Fall 2019 doodle marking the Southern Hemisphere. The sky-watchers will also witnessed “Super worm moon” for the first time in 19 years.

Why is it special this year?

Apart from the Spring Equinox, on March 21 the world will also witnessed Supermoon. This co-incidence last occurred in the year 2000. According to National Geographic, the moon of March 20 will reached its full phase and the full lunar disk will appeared 14 percent larger and 12 percent brighter than usual.

This March Supermoon was the last for 2019. The previous two Supermoons happened on January 21 and February 19. This Supermoon is called the ‘Super worm equinox moon’, simply because it coincides with equinox.


A Supermoon basically happens when the full moon coincides coincides with perigee- the moon's closest approach to Earth in its orbit. Supermoons make the moon appear a little brighter and closer than normal.

Google Doodle, on March 20, celebrated Spring Equinox 2019, a celestial event that marks the beginning of spring in many cultures. Spring Equinox is the first day of the season when the day and night are in equal length. An equinox is regarded as the instant of time when Earth’s equator passes through the center of the Sun, making it visible directly above it. This phenomenon occurs about twice a year, once on March 20 and then on September 23. It is called the Spring Equinox or the Vernal in the northern hemisphere. The word equinox finds its origin in Latin and means equal and night. Which means almost everywhere in the world, night-time and daytime will be 12 hours long.

This event marks the change of seasons and the how the light shifts to make the day time longer than the nights, meaning the end of winters and the beginning of warmer days or summers. On the day of the equinox, the sun rises directly in the east and sets directly in the west. One may also be able to witness the Super worm moon for the first time in 19 years. This phenomenon happened last time in 2000 when the fall moon landed close to the first day of the spring and it won’t happen again until 2030.


At 1:15 AM IST on March 20, the moon was 2,23,309 miles away from Earth and appeared larger and brighter than usual.
