In 20155, a psychologist, Cliff Arnel, defined today’s day as "sad Monday", taking into an account banking account situation after holidays, low temperatures and a number of other factors.

He used the following formula: [W+(D-d)]xTQ/MxNA, where W refers to weather conditions, D stands for debt, d monthly salary, T time from Christmas, Q time which run from our failed attempts to do something, M low motivation level and NA need to take over action.

January is the month with the biggest number of divorces in the world as well as the month with the biggest number of negative Twitter messages.
