To understand season dates, you must first understand the two different systems used to measure them: astronomical and meteorological. 1. Astronomical Seasons (Based on Earth's Orbit)
If you notice the astronomical dates changing slightly from year to year, it is due to the physics of Earth's orbit. It takes the Earth roughly 365.24 days to complete one full trip around the sun.
Astronomical seasons are the traditional seasons most people are familiar with. Because a year is not exactly 365 days, the precise dates of the solstices and equinoxes can shift by a day or two each year. Spring (Vernal Equinox to Summer Solstice) March 19–21 Ends: June 20–22 What's your favorite thing to do during each season

The meteorological system was created by scientists and weather forecasters for statistical consistency. Instead of dealing with shifting dates in the middle of a month, meteorologists break the year down into four neat, three-month periods based on the annual temperature cycle. Each season starts on the first day of a month and lasts exactly three calendar months. When Do the Seasons Start and End? (Northern Hemisphere)
