anthropic can now see what you're using claude for, down to the hour. the pattern is exactly what you'd expect.

from the june 26 anthropic economic index report. they changed their data pipeline to sample usage at the hourly level instead of weekly snapshots. now they can see the daily rhythm.

what they found:

sleep advice peaks around 5am. news questions peak at 7am local time. business email drafting traces the arc of the workday and hits a slight plateau at 10-11am. recipe requests are 2.3x more frequent at 6pm than the daily average. media recommendations concentrate in the evening.

on weekdays about 65% of claude conversations are work-related. on weekends that drops to around 50%. and the topics shift: business correspondence, marketing copy and slide decks give way to emotional support, medical questions and investment advice.

the tax day finding is the most striking one. on april 14, the day before the US filing deadline, tax-related conversations were 8x more common than on a typical day in May. on april 16 they dropped back to baseline.

claude code and the API follow a similar weekday/weekend rhythm but with a lower baseline of personal use. on weekends when people do use claude code, the tasks that fall the most are backend architecture and API debugging. the tasks that go up: AI agent design, quant trading and gaming.

people with technical jobs apparently use claude to work on evenings and weekends. and they use it to game on weekends too.

the whole thing reads like a heartbeat monitor for how people actually spend their time.
