Is this why I’m having such a terrible day?

January 22 is the most depressing day of the year, according to one headline-grabbing psychologist who, among other things cites fading memories of holidays as one reason for this being a particularly gloomy start to the working week.

Who is this headline-grabbing psychologist? A quick outbreak of hot, Google action turns up this:

Dr Cliff Arnall, a Cardiff University psychologist, devised the formula that shows today is the most depressing.

His equation takes into account six factors: weather, debt, time since Christmas, time since failing our new year’s resolutions, low motivational levels and the feeling of a need to take action.

Taken together they pinpoint today as ‘Blue Monday’.

So now you know.
