When does Spring start in 2021?

In the Northern Hemisphere, the astronomical Start of Spring is also known as the Spring equinox, and in 2021 it happens on March 20, at 5:37 a.m. EDT.

This year, Spring will last from March 20 until June 20, when Summer officially starts. 

What is the Spring Equinox?

The Spring Equinox, which is also called the Vernal or March Equinox, happens when the Sun heads north and crosses the equator line. When this happens, the Northern Hemisphere of the Earth starts to tilt more towards the Sun, which results in longer and warmer days. 

So, the Spring Equinox signals the arrival of Spring in the United States, and with it the nicer weather, and the blooming of flowers and plants. In the Southern Hemisphere, the Vernal Equinox signals the start of Autumn, as this hemisphere becomes tilted away from the Sun.

During the equinox, the day and night are nearly the same lengths, approximately 12 hours long each. It is at this point that the change happens when the days become longer and the nights become shorter. 

The end of Spring is signalled by the Summer Solstice, which happens in June, and marks the arrival of Summer in the Northern Hemisphere. 

Characteristics of Spring

It is during Spring that the temperature starts getting warmer, after months of cold and snow. Spring is also one of the wetter seasons. This is the reason why during Spring the snow begins to melt, and trees and flowering plants start blossoming again. 

One of the most identifying characteristics of Spring is its colors. Because plants and flowers start to bloom, the world becomes green and colorful again, after being bare and grey for so long during Winter. 

This season is also often connected with rebirth and regrowth. Farmers sow their seeds ready for harvest in the Summer, and animals awaken from their hibernation periods and others have their babies. 

However, Spring in the United States is not all flowers and sunshine. It is also during this season that tornadoes become more frequent in the Tornado Alley area. With Spring, there are also more thunderstorms and hail storms.

Important Dates associated with Spring

Spring has always had a big significance when it comes to dates and celebrations. In ancient times, it was during Spring that many pagan rituals and ceremonies took place, mainly weddings and other fertility-related rites. These traditions have, in one way or another, been passed on through to modern times, and today some of the most important dates we celebrate take place during Spring:

  • Mardi Gras and Carnival - In some cultures this is the festival of the new year.
  • Easter - The most important feast day in Christianity, celebrating the resurrection of Jesus Christ.
  • Passover - Where Jewish people celebrate their escape from slavery.
