Cornell researchers analyzed mood content in 2.4million tweets (based on word choice) and found that Saturdays and Sunday garnered the most positive expressions and Mondays the most negative – well, during the day anyway. Interestingly, Saturday and Sunday nights were way up (down) there too. On a design note, perhaps the lower graph should have inverted the scale?  (related article)

Interesting stats. At we’ve been tracking the mood of our users for 18 months and Wednesday seems to trend as the most unhappy day of the week from our research

Saturday at 11pm is both the happiest AND the angriest time of day? To declare which day is the best / worst, I suggest that they look at the net positive / negative comments. So +1 for positive and -1 for negative. Maybe the results would be the same, but the two charts don’t tell the full story

Good catch Brian. There’s too much multicollinearity between variables. The volume of tweets dictates these results and not the actual sentiment felt at a given time. Brian’s input may reveal more insight though..
