Is Blue Monday real?

Despite some very official-looking algebra, Blue Monday was actually invented by Sky Travel in a bid to boost summer holiday bookings.

In 2010 Dr Arnall revealed that he had simply picked a date when asked to work out the most depressing day of the year.

He said: “I was originally asked to come up with what I thought was the best day to book a summer holiday.

“When I started thinking about the motives for booking a holiday, reflecting on what thousands had told me during stress management or happiness workshops, there were these factors that pointed to the third Monday in January as being particularly depressing.

“But it is not particularly helpful to put that out there and say ‘there you are’ – it is almost a self-fulfilling prophecy that it is the most depressing day.”
