How are the seasons of fortune telling divided?

Excuse me, what is the monthly order in fortune telling? What is the monthly order? I don't quite understand what this means. I hope someone can answer it.

The December season, also known as the December season, is the outline of everything. The month order is not only the dividing line between January and January, but also the standard to measure the rise and fall of the middle branch of the eight characters, so the month order is extremely important in calculating the eight characters.

December order: beginning of spring in the first month, Jingzhe in February, Qingming in March, Long Summer in April, Miscanthus in May, Little Summer in June, beginning of autumn in July, White Dew in August, Cold Dew in September, beginning of winter in October, Heavy Snow in November and Slight Cold in December.
