From National Bureau of Economic Research:
The Business Cycle Dating Committee of the National Bureau of Economic Research maintains a chronology of the peaks and troughs of the US business cycle. The committee has determined that the U.S. economy will experience a monthly low in economic activity in April 2020. The previous peak of economic activity occurred in February 2020. The recession lasted for two months, which made it the shortest recession in the history of the United States.
This is the result graph (monthly) showing some key indicators:
