Got a case of the Tuesdays? People tend to be happier on the weekend than during the week, according to new research published by the National Bureau of Economic Research.

Interestingly, while happiness increases somewhat on the weekend, declines in worry, anger and stress are much larger. Stress is one-third less common on the weekend, the largest effect the weekend has on one of seven emotions measured in the study.

John Helliwell, with the University of British Columbia, and Shun Wang, with the Korea Development Institute, authored the study.

Helliwell and Wang looked at the Gallup/Healthways United States Daily Poll from 2008-12. The survey asked respondents about seven emotions: happiness, enjoyment, laughter, worry, sadness, anger and stress. Respondents said "yes" or "no" to questions about whether they felt an emotion during the previous day.

The authors found that full-time workers were more likely to feel emotions on the weekend than part-time ones.

Workers in offices without trust or partner-like bosses were more likely to have a change in emotion on the weekend. Having more social time is the other largest factor creating happier people on weekends.

"Taken together, the quality of the social contexts on and off the job are the primary forces behind weekend effects in the subjective well-being of the working population of the United States," Helliwell and Wang wrote.
