Mondays are considered to be the most depressing day of the week as people return to work; however, January 17 is said to be even worse.

The third Monday in January is considered to be the most depressing day of the year.

Dubbed “Blue Monday” by a professor at the University of Cardiff in Wales, it takes into account things like weather, Christmas debt and how we feel after the holidays.

About 20 per cent of Canadians will feel a touch of depression between November and March, while some feel seasonal effective disorder.

Experts said that the best way to deal with Mondays is to relax, try not to do anything too stressful and possibly treat yourself.
