Twelve hours later a third of the nation is on the job, and by eleven at night leisure has drawn its largest crowd of the day. Measured across all of 2024 and laid end to end, six ordinary activities trace a single national day — its long exhale at dawn, its working plateau, its evening handoff, and the slow return to bed.
