Etymology
Origin of midnight
before 900; Middle English; Old English midniht. See mid-, night
Explanation
Midnight is the moment at which one day ends and the next begins — it's twelve o' clock at night. Follow the Fairy Godmother's advice to Cinderella, and always get home before midnight. At midnight, the date changes, and the time changes from PM to AM. It's no surprise that midnight is the very middle of the night, the word itself stemming from the Old English mid-niht, from mid, "among" or "in the middle of," and night, from niht, which appropriately means both "night" and "darkness."
