Twitter Knows When You're Going To Be Sad, Hungover, And Late For Work

Data from the social network proves that we're all in pretty bad shape come Monday morning.

Posted on March 10, 2014, at 4:40 p.m. ET

Monday mornings for the average worker are pretty brutal, and Twitter has some compelling data to back it up. Twitter's data editor, Simon Rogers, combed through millions of tweets to try and define the network's collective mood at a given time and found that when it comes to feeling terrible at the beginning of the week, you're probably not alone.

In a blog post on the site Rogers explains his methodology:

Looking at the usage of different words and phrases in 2013 by day of the week and month tells you a lot about how the world tweets. We turned that data set into a ratio of Tweets containing those words in English per million posted.

The results are both disturbing and heartening. Twitter proves that "the Mondays" are, in fact, very real. Turns out all those whiny tweets might be good for something after all.

Twitter users are "feeling happy" in unusually high numbers on Fridays and Saturdays in March...

Users indicate they are at their happiest on Tuesdays in December and January, but given that Christmas Eve was on a Tuesday last year (as was New Year's Eve), the data is likely skewed (since Tuesdays in December and January are usually bleak and miserable). It seems users are least likely to publicly declare their happiness on Sundays in April. Maybe because they're too busy outside enjoying the winter thaw on their day off.

...which may account for why so many people are tweeting they're "hungover" on Sundays in March.

Sundays in March are big hangover days. Tuesdays and Wednesdays in January can be rough (New Year's Day 2013 probably accounts for some of this) as well as people trying to drink away the winter doldrums. And Thursdays and Fridays in November are no picnic, due in part to a little excess at Thanksgiving.

You're most likely to be "late for work" in the summer. How convenient.

Just look at that solid block of blue in midweek during the summer months. Slackers.

Lots of blue in the month of December proves seasonal depression is very real.

People start tweeting that they're "feeling sad" as summer gives way and falls and the dead of winter. December is, without a doubt, the "saddest" month of the year — I blame the holidays. And it would appear nobody wants to go back to work after a weekend off in July.
