If you thought Mondays were bad – it turns out Tuesdays are even worse, the Daily Telegraph reported.

A study by the London School of Economics monitored the mood swings of more than 22,000 people using an iPhone application called “Mappiness.”

Over a two-month period, an alert was sent to the study volunteers twice a day asking them how they felt, who they were with, what they were doing and whether they were at home. And the results showed that people felt at their lowest on Tuesdays.

“It seems plausible that on Monday, the weekend has not quite worn off,” study author, George MacKerron, said. “By Tuesday, [people] are well into the working week and the following weekend is not in sight.”
