A researcher from Cardiff University claims that the third Monday in January is the most depressing day of the year based on an equation that factors; weather, credit card debt from the holidays and failed New Year’s resolutions. While I’m all in favor of a good formula, I was a little skeptical that our emotions could be reduced to these three variables. In this week’s TIME column I discuss some interesting findings. The chart below didn’t make it into the column.

You can see that spikes in searches on “depression” that happen in late November (we drew this chart limiting it to “depression” searches to the Health and Medical category to account for “great depression” searches). Visits to the official websites of leading anti-depressant medications show that they spike a few weeks in advance of “depression” searches, possibly a sign of pre-medication before the holidays? And the good news — depression (based on searches and visits to drug sites) appears to be on the decline.
