These holidays all have to do with food or other things that one would associate with Halloween, or they just happen to occur on the same day as the spookiest day of the year.

Frankenstein Friday is the last Friday in October of each year. In 2012, it falls on October 26. This day celebrates the birth of Frankenstein and his creator, Mary Wollstonecraft Shelley, who wrote Frankenstein when she was 21. How should one celebrate Frankenstein Friday? Have fun by watching a Frankenstein movie or by reading the book. You could even do both.
Devil's Night occurs on October 30, the night before Halloween. Since the 1930s, it has been a night of vandalism. Otherwise known as “Mischief Night”, it is full of pranks such as toilet papering trees and shrubs, soaping, and egging.
October 30, Haunted Refrigerator Night, is the night to find out what terrifying, horrible things lurk in the unopened containers that have been hiding in the back of your refrigerator for far too long. It is time to face up to the demons of mold and unknown, hair-sprouting foods of past dinners and show them who is boss.
October 30 is also National Candy Corn Day. So, after you have conquered your terrifying refrigerator, reward yourself by indulging in a handful of this sweet treat that consists mainly of corn syrup, honey, and sugar.
Beggars' Night, which occurs on October 31, is a regional term that describes the Halloween activity of trick-or-treating. This term is used in parts of Ohio, Iowa, Massachusetts, New Hampshire, and New York.
Books for Treats Day is also on October 31. Instead of candy, people are encouraged to give books for treats. Candy causes obesity and tooth decay, whereas books stretch a child's imagination and open the door to learning.
Halloween is the holiday observed annually each October 31. This day normally includes such activities as watching scary movies, telling bloodcurdling stories, visiting haunted houses, playing pranks, bobbing for apples, building bonfires, carving jack-o-lanterns, attending costume parties, and trick-or-treating.
October 31 is also National Caramel Apple Day. This is the day to put your apple on a stick, then roll it in hot caramel and perhaps sprinkle some nuts on it before you sink your teeth into it.
October 31, National Knock-Knock Jokes Day, is a day when most people are focused on things haunted and scary. Why not surprise them? Start every conversation with a knock-knock joke and make this a day full of laughs for everyone you meet.
National Magic Day, celebrated on October 31, is recognized by magicians worldwide as the day to honor Harry Houdini. This great magician died on this day in 1926 from peritonitis in a Detroit hospital.
Samhain, also on October 31, is what Wiccans call the holiday most of us know as Halloween. Sometimes called the Witch's New Year, it is a time when they honor those who have crossed over into the spirit world and it also celebrates the beginning of winter. This is not pronounced the way you might think it is, so before trying to say this one, you might want to look it up in the dictionary.
