In the middle of winter, Blue Monday emerges as the saddest day of the year, in contrast to Yellow Day (considered the happiest day). According to a mathematical formula, on that day, the overall conditions are the worst of the entire year, and we’re filled with more sadness, pessimism, and uncertainty for various reasons. In this article, we’ll explore what Blue Monday is all about, why it’s considered the saddest day, and how Culmia can help you brighten up this gloomy day.
Where does “Blue Monday” come from?

Given that Mondays are already tough enough on their own, the third Monday in January is also known as “Blue Monday”—a term that some people aren’t even familiar with.
The term was coined by Cliff Arnall, a psychologist and professor at Cardiff University, who first used it back in 2005 after reportedly devising a mathematical formula to determine the saddest day of the year. This date is calculated based on a number of factors, such as the weather, holiday debt, motivation, and the time that has passed since the holidays.
The formula would be [C+(D-d)]TI / MNa, where each of the parameters is as follows: C stands for the weather, D represents the expenses and debts incurred during Christmas, d represents the money received in January, T is the time that has elapsed since Three Kings’ Day, and “l” denotes the period since the last unsuccessful attempt to quit a bad habit. The result of this calculation should be divided by M (level of motivation) over Na (need to take action).
Why is it the saddest day of the year?
All of the factors mentioned above influence people’s mood and disposition on that day, considered the gloomiest Monday of the entire year.
A combination of factors—from unmet New Year’s resolutions to the gloomy winter weather and the financial hangover after the holidays—contributes to the melancholic atmosphere of that day. It’s all just one calamity after another. Furthermore, everyone’s overindulgence in food and drink, combined with the fact that a new year is symbolically beginning, creates not only the common post-holiday blues but also a rebound effect of wanting to make changes.
Why Blue?
On a mental level, the color “blue” is associated with low moods. It is directly linked to feelings of passivity and situations that can trigger processes leading to sadness and even depression.
In this case, this mood tends to be prevalent mainly in areas of the Northern Hemisphere that experience very harsh winters and have a significant lack of sunlight for quite some time.
There is a theory that suggests this association with the term “blue” is related to the “blues” genre of music, since it is characterized by its melancholic and pessimistic tone, and most of its lyrics deal with personal or social problems.

In short, in English, the word “blue” is used to refer to both sadness and the color blue. This coincidence has led to blue being commonly used as the color of sadness in many fields, such as advertising, film, and society in general.
