Whatever Happened to Friday Night?
The week has a heartbeat, and its rhythm is changing.
When Neal Caren, a sociologist at the University of North Carolina at Chapel Hill, recently dug into data from the American Time Use Survey to look at when people were hanging with their friends over the course of a week, he mapped out a pattern that reminded him of an EKG. He saw steady pulses of friend time every weekday evening after work hours, and then bigger spikes on Friday and Saturday nights—like an arrhythmia caused by having fun.
