Canonical US business cycle peaks and troughs as dated by the National Bureau of Economic Research (NBER) Business Cycle Dating Committee. Returns 35 cycles spanning December 1854 through the April 2020 trough. Each record includes the peak and trough months (YYYY-MM), the same dates as full ISO 8601 UTC timestamps (day 1 of the month), and the recession duration in months. Sourced from the static JSON file at data.nber.org/data/cycles/business_cycle_dates.json. No new recession has been declared by the BCDC since the April 2020 trough, so this dataset changes only when the committee announces a new peak or trough.
