How many days until spring starts 2021 - opinion

Sunday, March 20, A.

Times are based on Eastern time ET. Subtract 3 hours for Pacific time, 2 hours for Mountain time, 1 hour for Central time, and so on. More specifically, the start of each season is marked by either a solstice for winter and summer or an equinox for spring and autumn. Because of leap years, the dates of the equinoxes and solstices can shift by a day or two over time, causing the start dates of the seasons to shift, too.

In contrast, the meteorological start of a season is based on the annual temperature cycle and the month calendar. According to this definition, each season begins on the first of a particular month and lasts for three months: Spring begins on March 1, summer on June 1, autumn on September 1, and winter on December 1. As the Earth progresses through its orbit during the year, the tilt causes different parts of the Earth to be exposed to more or less sunlight, depending on whether we are tilted towards or away from the Sun.
