Singles' Day.

Singles' Day is the world's biggest shopping day, occuring on the 11th of November every year. In Chinese, the name is originally referencing "bare sticks holiday" because of how the date looks numerically (11:11). Singles' Day's popularity as a commercial event was created by Alibaba's founder Jack Ma in 2009. On November 11, 2018, Alibaba hit a new record of $30.8 billion in sales.
