# Blue Monday, the saddest day of the year according to science

Between the cold and the debt left over from the December holiday, the third Monday in January arrives, also known as ‘Blue Monday‘ As for ‘Blue MondayIt promises to be the saddest day of the year.

The concept of “Blue Monday” arose in 2005 thanks to a psychologist Cliff Arnallwho developed a mathematical equation to calculate it.

The formula uses qualitative factors that include the idea that by the third Sunday in January, many people haven’t recovered from some of the economic, dietary, or emotional excesses of year-end parties.

It also states that by that date, people have realized that the resolutions set for the new year can be very difficult to achieve, causing deep sadness.

In addition, the idea was added that Monday is considered the most unpleasant day of the week.

The mathematical formula developed by Arnal is as follows:

(C + (Dd) 3 / 8xTI MxNA) = The saddest day of the year

C = is the climatic factor.

D = Debt earned during vacations.

D = Money to be collected until the end of January.

T = is the time elapsed since the December holiday

I = indicates the period since the last failed attempt to break a bad habit or start a new one

M = remaining drivers.

NA = Need for action to change lives.

Arnall states that all of the above can lead to specific depressive symptoms such as lack of energy, fatigue, and sadness.

However, the concept of “blue Monday” is considered pseudoscience because it does not correspond to any approved scientific method and has been highly questioned in the scientific community.

In addition, the concept is known to be used by companies and advertising campaigns to make money, as was the case with the advertising campaign launched by the tourism agency which suggested that to counter grief, it was better to take a trip with the company’s services.
