It must be said that many argue that Blue Monday does not exist, and they are probably right. To reach this conclusion Cliff Arnall, the psychologist who is credited with the scientific study on which the Blue Monday thesis is based has developed an equation that considers several variables. They range from the weather conditions to the money spent during the Christmas holidays, coming to the sudden senses that derive from it, and the motivational decline due to the period after the holidays. But will it all be true?
However, we also owe Arnall the calculation that produced the happiest day of the year. It is the third Friday of June. In a similar way, but in the opposite way, it seems that the psychologist’s reasons are outdoor activity, social relationships, nature, and temperature. But even the Happiest Day of the year can be considered a hoax. The Wall’s ice cream company paid Arnall around 1,650 pounds to support the creation of this day on a mathematical basis.
