The Chinese words for “520” sound very like Wo Ai Ni, the Chinese words for “I love you.” And thus May 20 has become an unofficial “Internet Valentine's Day” in China. May 20 has a very different meaning in the tiny unincorporated town of Codell Kansas, where May 20 is “Cyclone day,” commemorating the day on which tornadoes struck the town in three consecutive years from 1916 - 1918. Clearly there are a variety of reasons that May 20 is a date in history that deserves to be remembered.
