Abstract in brief

The study investigates how social factors influence sleep patterns, using a smartphone app called ENTRAIN to collect global sleep data.
The research reveals that societal pressures can delay bedtimes and reduce overall sleep duration, with average bedtimes being a key predictor of sleep length.
Additionally, findings indicate that age significantly impacts sleep timing and habits, with women generally getting more sleep, and outdoor light exposure leading to earlier bedtimes.

Ironic mascot given @duolingo's unfriendly to night owls. Days are divided at midnight, though biological midnight is ~3am for most adults. Also use lesson end time instead of start to decide which day, even if most was done before
