Final answer:
During the Halloween season, Earth is positioned after the autumnal equinox and before the winter solstice in the Northern Hemisphere, which happens around September 21, marking a period of equal day and night length.
Step-by-step explanation:
The Earth's position during the Halloween season in the Northern Hemisphere is after the autumnal equinox and before the winter solstice.
During the Halloween season, which occurs at the end of October, the Northern Hemisphere experiences autumn. The autumnal equinox typically occurs around September 21, when the Sun crosses the celestial equator. This marks the point when the day and night are approximately equal in length, leading to the term 'equinox' from the Latin words for 'equal night.' After this point, days start to become shorter, and nights longer as the Earth progresses on its orbit towards the winter solstice in December when the North Pole is tilted furthest away from the Sun, leading to the shortest day and longest night of the year.
