Jan 18 Word of the Day
1. Blue Monday is the most depressing day of the year, calculated by Dr. Cliff Arnall, a researcher at the University of Cardiff's Center for Lifelong Learning.
Factors used to calculate the date included weather conditions, debt level, time since Christmas, time since failing our New Year's resolutions, low motivation and feeling the need to take action.

In 2005 the date was calculated as January 24th, in 2006 it was January 23rd, and in 2007 it was January 22nd.

2. A song by the hard rock band Orgy from their album Candy Ass.
1. Guy: "Aw man, I feel like absolute shit today."
Friend: "Yeah, same here. I hate Blue Monday."

2. "I wish I could sing Blue Monday to my ex-girlfriend, she's such a bitch."
