Last year's recession is now the shortest on record:

The COVID-19 recession is now the deepest, but also shortest, in U.S. history, according to the National Bureau of Economic Research (NBER). Officials found that the contraction lasted just two months, from February 2020 to the following April.

While the nation's GDP plunged 31.4% during that two month span in the second quarter, it also epically rebounded the next period, rising 33.4% on the back of unprecedented fiscal stimulus.

"In determining that a trough occurred in April 2020, the committee did not conclude that the economy has returned to operating at normal capacity," the NBER said in a press release. "The committee decided that any future downturn of the economy would be a new recession and not a continuation of the recession associated with the February 2020 peak. The basis for this decision was the length and strength of the recovery to date."
