I use the Worldometer stats. Not sure if their days ends at 00:00 GMT or EST. Either way, it's a 24 hour day measure.
I would also add that we are 13 days into the mitigation. COVID-19 infected people on average die about 20 days after infection. We'll see what happens, but no way will it be even close to 1000.
Death at day 20 is incorrect
