January 6, 2014
According to Cosmopolitan, January 6th is National Affair Day aka the supposed day when people are most likely to start an affair. This is based on the fact that IllicitEncounters.com, a British affair website sees the sharpest spike in people signing up. They also note that almost 6% of Britain's married population will be on this site by the end of January. Time to tell your boyfriend to watch his ass as apparently January is National Douchebag Month. I guess it's only logical that the only way to follow the most wonderful time of the year is the most adulterous time of the year.
