It may come as a surprise to many, but Halloween used to be an actual State holiday here. Schools, banks, and other businesses were closed in observance of that very important date. Ok, maybe it wasn’t specifically because it was Halloween, although Vegas makes it seem like that was the reason! October 31, 1864, was the day Nevada became the 36th state of the Union. The official title is “Nevada Day” and is now celebrated on the last Friday of the month. But don’t tell the Vegas tourists that!
