For much of history, and in many cultures today, the seasons are defined by the Earth's tilt on its axis relative to the Sun. This is known as the astronomical definition.

The seasonal cycle is punctuated by four significant events: the spring equinox, summer solstice, autumnal equinox, and winter solstice. These dates mark the beginning and end of each season, and are a result of the Earth's tilt on its axis (approximately 23.5 degrees) and its orbital path around the Sun. when the seasons start and end
