Based on the rate of increase of the tweets, I picked the following dates.

• July 13th, 2020 (3.6M tweets),
• Sept 9th, 2020 (3.1M tweets),
• Oct 2-3rd, 2020 (3.8M tweets)
• Dec 21st, 2020 (2.4M tweets). We need to check if the dates above are worth using for our analysis and find more days from 2021.

An update on the dates I chose based on the rate of tweet number increase: I made a quick research and why a peak happened in the number of tweets and found the following information:

• July 13th, 2020 (3.6M tweets) President Donald Trump makes his first public appearance wearing a face-mask. WHO reports that the United States and Brazil made up half of the daily increase in coronavirus cases globally.

• Sept 9th, 2020 (3.1M tweets) More than 500,000 U.S. children have been diagnosed with COVID-19. The United States announces it will stop screening international arrivals for COVID-19

• Oct 2-3rd, 2020 (3.8M tweets) President Trump announced that he tested positive for Covid-19.

• Dec 21st, 2020 (2.4M tweets). The European Union approves the Pfizer-BioNTech vaccine. U.S. President-elect Joseph R. Biden receives the Pfizer-BioNTech coronavirus vaccine on live television.

I believe Oct 2-3rd and Dec 21st are the dates we can be interested in more but I will leave it up to the whole team to decide which dates are worth considering in our research.
