Can we figure out how long schools and businesses were closed in affected areas in 2009? It might give us a clue as to when things will return to normal this year, since most of us who do not get a serious case of the virus will be most affected by how long our lives are on hold.
Wuhan was closed January 23 - March 14, 52 days. 7 1/2 weeks.
If, unironically, you want to start with March 14 here, then the end date is Tuesday, May 5, 2020.
