Everything You Need to Know about "Blue Monday"

Blue Monday is believed to be the gloomiest and most depressing day in the whole year.

It usually falls on the third Monday of January every year, a time to embark on new endeavors and challenges. It can also fall on the second or fourth.

For many people, that day is completely miserable as their bodies would be still recovering from Christmas.

The first Blue Monday was marked in 2005 when the idea was conceived by life coach and happiness consultant Dr. Cliff Arnall.

Cliff published a formula to work out the most depressing day of the year, using factors such as the weather, debt, the amount of time elapsed since Christmas.

Arnall believed this formula could be used to predict when people would be poking trips to sunny holiday destinations.

Since coming up with the formula, Dr. Arnall has urged Brits to "refute the whole notion" of Blue Monday.

In 2013, he told The Daily Telegraph that "it is not particularly helpful to put that out there and say ‘there you are’,” going on to describe Blue Monday as a self-fulfilling prophecy.

Many have affirmed that there is no way you could assign numerical values to factors such as "weather".

Stephen Buckley, mental health charity Mind’s head of information, previously said: “There is no credible evidence behind the concept of a most depressing day of the year."
