My bad, ran that date based on today's date, when it should have been from 2/27/33 until 1/6/21. 88 years less 52 days. Going back that amount of time from 2/27/33 brings us to April 20, 1845. Or within a couple of days of that, if one bothers with adding up the leap years and month lengths. April 10, 1845, there was a huge fire in Pittsburgh.
