Well the definition of a technical recession is two or more consecutive quarters of negative GDP growth. We hit that in the first and second quarters of the year with approximately -1.3% and -9% respectively (on a non-annualized basis). Every major bank is expecting robust growth in third quarter around 7-9% (non-annualized) and a modest increase in the fourth quarter. So on in this vein, we will no longer be in a technical recession as of the end of the third quarter.
A recession more generally (and not technically) can compare year-over-year quarterly results. From this perspective, 3rd and 4th quarter of this year are very likely to be lower than 3rd and 4th quarter last year, which could qualify as a recession (even though the economy is technically growing quarter over quarter). Barring a setback, we would expect this "recession" to have ended by the end of the first quarter of 2021, since (again barring a setback) Q1 2021 GDP will be higher than Q1 2020.
However, even if that were the case where no way you look at it is the economy in "recession," I think it will be clear that the economy is likely to be pretty poor at that point given where we were before Covid happened, so the classification of recession or not is missing the forest for the trees.
I think the NBER's criteria (the basis by which the US is "officially" in recession or expansion) is relevant here. They don't use the commonly held definition about 2 consecutive quarters in contraction:
While the popular definition of a recession is “two consecutive quarters of negative real gross domestic product (GDP) growth,” the NBER does not strictly abide by this designation (note 2). Instead, the committee broadly defines a recession as a “significant decline in economic activity spreading across the economy, lasting more than a few months.”
This is what they said about the current recession, as of 7 weeks ago:
The committee's view is that while each of the three criteria—depth, diffusion, and duration—needs to be met individually to some degree, extreme conditions revealed by one criterion may partially offset weaker indications from another. For example, in the case of the February 2020 peak in economic activity, we concluded that the drop in activity had been so great and so widely diffused throughout the economy that the downturn should be classified as a recession even if it proved to be quite brief.
