Meteorological seasons differ from astronomical seasons. For example, meteorological spring is based on annual temperature cycles, whereas astronomical spring is based on Earth’s rotation around the sun, WCNC reports.
In 2022, in the northern hemisphere, astronomical spring, also known as the spring or vernal equinox, when there are equal hours of sunlight and night, occurs on Sunday, March 20, at 11:33 AM EDT, according to almanac.com. After this date and the northern hemisphere, the Earth begins to tilt more toward the sun, bringing increased daylight and warming temperatures. It’s the opposite in the southern hemisphere, marking the start of autumn.
