Change Year

Seasons split the year into four unique periods: Spring, Summer, Autumn/Fall, and Winter. Each season is characterized by its own weather patterns, daylight hours, and changes in plant and animal behavior. These shifts occur due to the Earth's yearly journey around the Sun and its tilted axis. Here are the astronomical dates for the year 2020, accounting for both the northern and southern hemispheres.
