Today is the worst day of the year, according to maths

It's cold, it's January, we have a hangover and crippling work fear - and it looks like things are only getting worse.

With the festivities and movie days a distant memory, we have thoroughly settled back to the daily grind and we're battling through January one day at a time. While you might have the feeling this is the worst time of the year, it's nice to have some scientific evidence to back you up - and justify the bottom lip. According to a formula created by psychologist Dr. Cliff Arnall, today - January 18 - is the most depressing day of the year. Here's the formula: W is weather, D is debt, d is monthly salary, T is the time passed since Christmas, Q is the time since the failure of an attempt to give something up, M is low motivational level and Na is the need to take action. You add all that to the fact that today is a Monday, and you've got the perfect cocktail for a sh*tty day. The formula was created back in 2005, and while some claim it was merely an airline PR stunt to get people to book flights, we completely agree that mid-January is the WORST and today is the day we feel it most. But don't worry, there is a bright side - things will be better from tomorrow.
