The day is a festival of the single persons. “光棍“means single persons

光棍儿 = single person / bachelor So a single person's festival. Five years in China and I have never hear of this one.

"光棍"means that someone is a single person.Just as you see "11th of November "is11.11.And 1looks like a bark and it is slippy.So, 11th of November is a festival that for the singles.

I happened to find the following explanation when I was surfing the Internet. I hope this helps. ========================= An old story goes that once there were four single men, leading very boring lives. None of them were married, or had lovers, or did anything exciting. They just sat around all day and played Mahjong. One day they played Mahjong from 11 in the morning until 11 at night. During the game, no matter who won, the winning card was always the 'four columns' card (the card shows four independent, parallel columns in two lines). Even more of a coincidence, it was Nov 11, or 11/11. In order to commemorate the day, they nicknamed it Singles Day. Singles Day was first celebrated at various universities in Nanjing, capital city of Jiangsu Province during the 1990s. It got the name Singles Day because the date is comprised of four "ones". These college students have since graduated, and carried their university tradition into society. Singles Day is now a special day for all fashionable youths. The main way to celebrate Singles Day is to have dinner with your single friends, but it's important that each person pay their own way to show their independence. People also hold 'blind date' parties in an attempt to bid goodbye to their single lives. Many singles also choose to say goodbye to their single lives on this day. Many attend 'blind date' parties and many people choose to marry on this day. In addition to meaning 'single' the four 'ones' of the date can also mean 'only one' as in 'the only one for me.' Some people will use this date and this meaning to tell their special someone that they are the only 'one' in their heart.
