Massachusetts' Daily Dashboard (where I get the information for these posts) will be taking Christmas Day and New Year's Day off. As the COVID-19 Response Reporting page notes:
COVID-19 dashboard reports will NOT be published on Christmas Day, Friday, December 25th or on New Year's Day, Friday, January 1st. Reports published on December 26 and on January 2 will each include two days of COVID-19 data.
