According to some shrewd scientists, today is the Day of Gloom. Namely, the dire convergence of all our seasonal woes, the most depressing day of 2006 is today, January 23, as identified by psychologist Dr Cliff Arnall of Cardiff University's Centre for Lifelong Learning.

Taking into account factors such as foul weather, Christmas debts, the lingering effects of seasonal overindulgence, failed New Year's resolutions and generally reduced motivation, Arnall's worst day "formula" is ([W + (D-d)] x TQ) ÷ (M x NA). (W: weather, D: debt, d: money due in January pay, T: time elapsed since Christmas, Q: time since failed New Year's resolutions to quit smoking, drinking etc, M: general motivational levels, NA: the need to take action.)
