Defined by the Earth's position relative to the sun (solstices and equinoxes). Astronomical seasons usually start around the 21st of the month, making the seasons technically overlap with the next month.
The need for consistent record-keeping led to the creation of the . This is the "verified" month-based system you're asking about. Developed in the early 1900s, it breaks the year into four neat, three-month blocks that align perfectly with our calendar.
