It's Dec. 12, 2012 also know as 12/12/12, or 12-12-12 depending on whether you prefer backslashes or dashes.
It's the last time we will experience a sequential day, month, and year combination in our lifetimes. The next time will be 10/10/10 in 2110.
Mathematics and superstition
The number 12-12 is one of the combinations that can bring good luck and fortune in China, according to the Bangkok Post. Dec. 12 stands for love so there will be a lot of weddings and scheduled births. A greater urgency to have children was felt on 11-11-11 (eternal love) and 10-10-10 (perfection).
Fans of the number 12, also known as "dozenalists," say the real time to celebrate is 2016 because they are counting in base 12, also known as the duodecimal, according to Wikipedia. The number twelve, a highly composite number, is the smallest number with four non-trivial factors (2, 3, 4, 6). As a result of this increased factorability and its divisibility, it is sometimes considered the most optimal number system.
