Halloween explains October and also, as one commenter mentioned, Orange. The proximity to Thanksgiving and the end of a time (day, work week, year) creates a sense of uniformity across these. And lastly, sunset and twilight can bring out the orange color of the landscape more, leading to more meaningful moments and a stronger connection to the time of day.

Also the oct in October is a prefix that means 8 so like 8:00pm. Fun fact: before the Julian calendar was established, October was the 8th month
