The fall equinox (and also the spring equinox) is at a time/day/date in the year when, in all parts of the earth, the length of the day is the same as the length of the night.
Although technically this is not absolutely and precisely so, the general principle of equal hours of sunlight and darkness on that day holds true for all parts of the globe, regardless of latitude or longitude.
