October 31st is All Hallow's Eve, or Halloween. However, did you know that, depending on where you are located, people call the night before Halloween by different names? Why October 30th even has alternative names is a question all in itself, but as Mental Floss lists here, it is subject to varying regionalisms. For example, if you were living in Philadelphia or New Jersey, then you might be familiar with the term "Mischief Night" which is what they called October 30th in those parts. The reason for this is that people would go out and about doing some harmless pranking on the night before the official trick-or-treating begins.
Another very intriguing nickname for October 30th is "Cabbage Night" which is unique to New England. The term is used to refer to delinquency, and alludes to something that happened in the 1800s when people still had cabbage farms. Young hooligans would uproot cabbages and throw them at people's houses. It's a bit similar to what Nebraskans called October 30th, "Corn Night", and as you've guessed, it's because some youth would throw ears of corn at people's porches. For the rest of the regional names of the night before Halloween, check it out on Mental Floss.
