There are 24 seasons in a year. Is Dreadwind one of them?

The 24 solar terms are: beginning of spring, Rain, Sting, Equinox, Qingming, Grain Rain, Changxia, Xiaoman, Mangzhong, Summer Solstice, Xiaoxia, Daxia, beginning of autumn, Early Summer, Bailu, Autumn Equinox, Cold Dew, Early Frost, beginning of winter, Light Snow, Heavy Snow, Winter Solstice, Slight Cold and Severe Cold. Each solar term is about half a month apart and divided into twelve months. The beginning of the month is called the solar term, and the middle of the month is called "Zhongqi". The so-called "qi" refers to meteorology and climate.

"Evil" refers to the legendary evil spirits and so on.

"Dreadwind" refers to the evil spirits in the sky.

The reason why Independence Day was translated into "Dreadwind" should be that the translator compared aliens to evil spirits from outer space.
