What is Blue Monday?

The concept of Blue Monday (or “Blue Monday” in French) considered to be the most depressing day of the year, was popularized by a advertising campaign from the English television channel Sky Travel. According to the channel, this day would constitute the convergence point of several negative parametersleading to a drop in morale or even temporary depression such as:

• a short day, with a lack of light
• the cold weather which has lasted for several weeks,
• the post-Christmas holiday period,
• the salary which has not yet been paid,
• stopping good resolutions,
• Monday which for some represents the day they return to work…

All these parameters would be likely to modify the circadian rhythms responsible for regulating our mood. So we would feel a little more depressed, less motivated and more passive this day, even if scientificallyno study has confirmed what a postulate.

What is the exact origin of Blue Monday?

The date of Blue Monday was first calculated in 2005 in a press release reporting the words of Dr Cliff Arnall, psychologist and at that time, tutor at the Center for Lifelong Learning at Cardiff University (Wales). . In this document there was a formula (see below) allowing you to calculate the date of the most depressing day of the year (with parameters such as the temperature outside, the time since Christmas, etc.). The formula has since been considered to be more anecdotal than scientific by Dr Arnall.

To calculate the most depressing day of the year, Dr Arnall used this formula (remember that there is no scientific basis):

[W + (D – d)] x T(Q) / M x N with :

• W: the weather
• (D – d): the difference in debts contracted during the holiday period with the ability to repay before the next payday
• T: the time since Christmas
• Q: How long has it been since New Year's resolutions?
• M: lack of motivation
• N: the need to act
